Vulkan® 1.3.283 - A Specification

20. Drawing Commands

Drawing commands (commands with Draw in the name) provoke work in a graphics pipeline. Drawing commands are recorded into a command buffer and when executed by a queue, will produce work which executes according to the bound graphics pipeline. A graphics pipeline must be bound to a command buffer before any drawing commands are recorded in that command buffer.

Each draw is made up of zero or more vertices and zero or more instances, which are processed by the device and result in the assembly of primitives. Primitives are assembled according to the pInputAssemblyState member of the VkGraphicsPipelineCreateInfo structure, which is of type VkPipelineInputAssemblyStateCreateInfo:

// Provided by VK_VERSION_1_0
typedef struct VkPipelineInputAssemblyStateCreateInfo {
    VkStructureType                            sType;
    const void*                                pNext;
    VkPipelineInputAssemblyStateCreateFlags    flags;
    VkPrimitiveTopology                        topology;
    VkBool32                                   primitiveRestartEnable;
} VkPipelineInputAssemblyStateCreateInfo;

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
flags is reserved for future use.
topology is a VkPrimitiveTopology defining the primitive topology, as described below.
primitiveRestartEnable controls whether a special vertex index value is treated as restarting the assembly of primitives. This enable only applies to indexed draws (vkCmdDrawIndexed, and vkCmdDrawIndexedIndirect), and the special index value is either 0xFFFFFFFF when the indexType parameter of vkCmdBindIndexBuffer is equal to VK_INDEX_TYPE_UINT32, or 0xFFFF when indexType is equal to VK_INDEX_TYPE_UINT16. Primitive restart is not allowed for “list” topologies.

Restarting the assembly of primitives discards the most recent index values if those elements formed an incomplete primitive, and restarts the primitive assembly using the subsequent indices, but only assembling the immediately following element through the end of the originally specified elements. The primitive restart index value comparison is performed before adding the vertexOffset value to the index value.

topology must be a valid VkPrimitiveTopology value

// Provided by VK_VERSION_1_0
typedef VkFlags VkPipelineInputAssemblyStateCreateFlags;

VkPipelineInputAssemblyStateCreateFlags is a bitmask type for setting a mask, but is currently reserved for future use.

To dynamically control whether a special vertex index value is treated as restarting the assembly of primitives, call:

// Provided by VK_VERSION_1_3
void vkCmdSetPrimitiveRestartEnable(
    VkCommandBuffer                             commandBuffer,
    VkBool32                                    primitiveRestartEnable);

commandBuffer is the command buffer into which the command will be recorded.
primitiveRestartEnable controls whether a special vertex index value is treated as restarting the assembly of primitives. It behaves in the same way as VkPipelineInputAssemblyStateCreateInfo::primitiveRestartEnable

This command sets the primitive restart enable for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_PRIMITIVE_RESTART_ENABLE set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineInputAssemblyStateCreateInfo::primitiveRestartEnable value used to create the currently active pipeline.

20.1. Primitive Topologies

Primitive topology determines how consecutive vertices are organized into primitives, and determines the type of primitive that is used at the beginning of the graphics pipeline. The effective topology for later stages of the pipeline is altered by tessellation or geometry shading (if either is in use) and depends on the execution modes of those shaders.

The primitive topologies defined by VkPrimitiveTopology are:

// Provided by VK_VERSION_1_0
typedef enum VkPrimitiveTopology {
    VK_PRIMITIVE_TOPOLOGY_POINT_LIST = 0,
    VK_PRIMITIVE_TOPOLOGY_LINE_LIST = 1,
    VK_PRIMITIVE_TOPOLOGY_LINE_STRIP = 2,
    VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST = 3,
    VK_PRIMITIVE_TOPOLOGY_TRIANGLE_STRIP = 4,
    VK_PRIMITIVE_TOPOLOGY_TRIANGLE_FAN = 5,
    VK_PRIMITIVE_TOPOLOGY_LINE_LIST_WITH_ADJACENCY = 6,
    VK_PRIMITIVE_TOPOLOGY_LINE_STRIP_WITH_ADJACENCY = 7,
    VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST_WITH_ADJACENCY = 8,
    VK_PRIMITIVE_TOPOLOGY_TRIANGLE_STRIP_WITH_ADJACENCY = 9,
    VK_PRIMITIVE_TOPOLOGY_PATCH_LIST = 10,
} VkPrimitiveTopology;

VK_PRIMITIVE_TOPOLOGY_POINT_LIST specifies a series of separate point primitives.
VK_PRIMITIVE_TOPOLOGY_LINE_LIST specifies a series of separate line primitives.
VK_PRIMITIVE_TOPOLOGY_LINE_STRIP specifies a series of connected line primitives with consecutive lines sharing a vertex.
VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST specifies a series of separate triangle primitives.
VK_PRIMITIVE_TOPOLOGY_TRIANGLE_STRIP specifies a series of connected triangle primitives with consecutive triangles sharing an edge.
VK_PRIMITIVE_TOPOLOGY_TRIANGLE_FAN specifies a series of connected triangle primitives with all triangles sharing a common vertex.
VK_PRIMITIVE_TOPOLOGY_LINE_LIST_WITH_ADJACENCY specifies a series of separate line primitives with adjacency.
VK_PRIMITIVE_TOPOLOGY_LINE_STRIP_WITH_ADJACENCY specifies a series of connected line primitives with adjacency, with consecutive primitives sharing three vertices.
VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST_WITH_ADJACENCY specifies a series of separate triangle primitives with adjacency.
VK_PRIMITIVE_TOPOLOGY_TRIANGLE_STRIP_WITH_ADJACENCY specifies connected triangle primitives with adjacency, with consecutive triangles sharing an edge.
VK_PRIMITIVE_TOPOLOGY_PATCH_LIST specifies separate patch primitives.

Each primitive topology, and its construction from a list of vertices, is described in detail below with a supporting diagram, according to the following key:

Vertex

A point in 3-dimensional space. Positions chosen within the diagrams are arbitrary and for illustration only.

Vertex Number

Sequence position of a vertex within the provided vertex data.

Provoking Vertex

Provoking vertex within the main primitive. The tail is angled towards the relevant primitive. Used in flat shading.

Primitive Edge

An edge connecting the points of a main primitive.

Adjacency Edge

Points connected by these lines do not contribute to a main primitive, and are only accessible in a geometry shader.

Winding Order

The relative order in which vertices are defined within a primitive, used in the facing determination. This ordering has no specific start or end point.

The diagrams are supported with mathematical definitions where the vertices (v) and primitives (p) are numbered starting from 0; v₀ is the first vertex in the provided data and p₀ is the first primitive in the set of primitives defined by the vertices and topology.

To dynamically set primitive topology, call:

// Provided by VK_VERSION_1_3
void vkCmdSetPrimitiveTopology(
    VkCommandBuffer                             commandBuffer,
    VkPrimitiveTopology                         primitiveTopology);

commandBuffer is the command buffer into which the command will be recorded.
primitiveTopology specifies the primitive topology to use for drawing.

This command sets the primitive topology for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_PRIMITIVE_TOPOLOGY set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineInputAssemblyStateCreateInfo::topology value used to create the currently active pipeline.

Valid Usage

20.1.1. Topology Class

The primitive topologies are grouped into the following topology classes:

Table 20. Topology classes
Topology Class	Primitive Topology
Point	`VK_PRIMITIVE_TOPOLOGY_POINT_LIST`
Line	`VK_PRIMITIVE_TOPOLOGY_LINE_LIST`, `VK_PRIMITIVE_TOPOLOGY_LINE_STRIP`, `VK_PRIMITIVE_TOPOLOGY_LINE_LIST_WITH_ADJACENCY`, `VK_PRIMITIVE_TOPOLOGY_LINE_STRIP_WITH_ADJACENCY`
Triangle	`VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST`, `VK_PRIMITIVE_TOPOLOGY_TRIANGLE_STRIP`, `VK_PRIMITIVE_TOPOLOGY_TRIANGLE_FAN`, `VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST_WITH_ADJACENCY`, `VK_PRIMITIVE_TOPOLOGY_TRIANGLE_STRIP_WITH_ADJACENCY`
Patch	`VK_PRIMITIVE_TOPOLOGY_PATCH_LIST`

20.1.2. Point Lists

When the topology is VK_PRIMITIVE_TOPOLOGY_POINT_LIST, each consecutive vertex defines a single point primitive, according to the equation:

: p_i = {v_i}

As there is only one vertex, that vertex is the provoking vertex. The number of primitives generated is equal to vertexCount.

20.1.3. Line Lists

When the primitive topology is VK_PRIMITIVE_TOPOLOGY_LINE_LIST, each consecutive pair of vertices defines a single line primitive, according to the equation:

: p_i = {v_2i, v_2i+1}

The number of primitives generated is equal to ⌊vertexCount/2⌋.

The provoking vertex for p_i is v_2i.

20.1.4. Line Strips

When the primitive topology is VK_PRIMITIVE_TOPOLOGY_LINE_STRIP, one line primitive is defined by each vertex and the following vertex, according to the equation:

: p_i = {v_i, v_i+1}

The number of primitives generated is equal to max(0,vertexCount-1).

The provoking vertex for p_i is v_i.

20.1.5. Triangle Lists

When the primitive topology is VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST, each consecutive set of three vertices defines a single triangle primitive, according to the equation:

: p_i = {v_3i, v_3i+1, v_3i+2}

The number of primitives generated is equal to ⌊vertexCount/3⌋.

The provoking vertex for p_i is v_3i.

20.1.6. Triangle Strips

When the primitive topology is VK_PRIMITIVE_TOPOLOGY_TRIANGLE_STRIP, one triangle primitive is defined by each vertex and the two vertices that follow it, according to the equation:

: p_i = {v_i, v_i+(1+i%2), v_i+(2-i%2)}

The number of primitives generated is equal to max(0,vertexCount-2).

The provoking vertex for p_i is v_i.

Note

The ordering of the vertices in each successive triangle is reversed, so that the winding order is consistent throughout the strip.

20.1.7. Triangle Fans

When the primitive topology is VK_PRIMITIVE_TOPOLOGY_TRIANGLE_FAN, triangle primitives are defined around a shared common vertex, according to the equation:

: p_i = {v_i+1, v_i+2, v₀}

The number of primitives generated is equal to max(0,vertexCount-2).

The provoking vertex for p_i is v_i+1.

20.1.8. Line Lists With Adjacency

When the primitive topology is VK_PRIMITIVE_TOPOLOGY_LINE_LIST_WITH_ADJACENCY, each consecutive set of four vertices defines a single line primitive with adjacency, according to the equation:

: p_i = {v_4i, v_4i+1, v_4i+2,v_4i+3}

A line primitive is described by the second and third vertices of the total primitive, with the remaining two vertices only accessible in a geometry shader.

The number of primitives generated is equal to ⌊vertexCount/4⌋.

The provoking vertex for p_i is v_4i+1.

20.1.9. Line Strips With Adjacency

When the primitive topology is VK_PRIMITIVE_TOPOLOGY_LINE_STRIP_WITH_ADJACENCY, one line primitive with adjacency is defined by each vertex and the following vertex, according to the equation:

: p_i = {v_i, v_i+1, v_i+2, v_i+3}

A line primitive is described by the second and third vertices of the total primitive, with the remaining two vertices only accessible in a geometry shader.

The number of primitives generated is equal to max(0,vertexCount-3).

The provoking vertex for p_i is v_i+1.

20.1.10. Triangle Lists With Adjacency

When the primitive topology is VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST_WITH_ADJACENCY, each consecutive set of six vertices defines a single triangle primitive with adjacency, according to the equations:

: p_i = {v_6i, v_6i+1, v_6i+2, v_6i+3, v_6i+4, v_6i+5}

A triangle primitive is described by the first, third, and fifth vertices of the total primitive, with the remaining three vertices only accessible in a geometry shader.

The number of primitives generated is equal to ⌊vertexCount/6⌋.

The provoking vertex for p_i is v_6i.

20.1.11. Triangle Strips With Adjacency

When the primitive topology is VK_PRIMITIVE_TOPOLOGY_TRIANGLE_STRIP_WITH_ADJACENCY, one triangle primitive with adjacency is defined by each vertex and the following 5 vertices.

The number of primitives generated, n, is equal to ⌊max(0, vertexCount - 4)/2⌋.

If n=1, the primitive is defined as:

: p = {v₀, v₁, v₂, v₅, v₄, v₃}

If n>1, the total primitive consists of different vertices according to where it is in the strip:

: p_i = {v_2i, v_2i+1, v_2i+2, v_2i+6, v_2i+4, v_2i+3} when i=0
: p_i = {v_2i, v_2i+3, v_2i+4, v_2i+6, v_2i+2, v_2i-2} when i>0, i<n-1, and i%2=1
: p_i = {v_2i, v_2i-2, v_2i+2, v_2i+6, v_2i+4, v_2i+3} when i>0, i<n-1, and i%2=0
: p_i = {v_2i, v_2i+3, v_2i+4, v_2i+5, v_2i+2, v_2i-2} when i=n-1 and i%2=1
: p_i = {v_2i, v_2i-2, v_2i+2, v_2i+5, v_2i+4, v_2i+3} when i=n-1 and i%2=0

A triangle primitive is described by the first, third, and fifth vertices of the total primitive in all cases, with the remaining three vertices only accessible in a geometry shader.

Note

The ordering of the vertices in each successive triangle is altered so that the winding order is consistent throughout the strip.

The provoking vertex for p_i is always v_2i.

20.1.12. Patch Lists

When the primitive topology is VK_PRIMITIVE_TOPOLOGY_PATCH_LIST, each consecutive set of m vertices defines a single patch primitive, according to the equation:

: p_i = {v_mi, v_mi+1, …, v_mi+(m-2), v_mi+(m-1)}

where m is equal to VkPipelineTessellationStateCreateInfo::patchControlPoints.

Patch lists are never passed to vertex post-processing, and as such no provoking vertex is defined for patch primitives. The number of primitives generated is equal to ⌊vertexCount/m⌋.

The vertices comprising a patch have no implied geometry, and are used as inputs to tessellation shaders and the fixed-function tessellator to generate new point, line, or triangle primitives.

20.2. Primitive Order

Primitives generated by drawing commands progress through the stages of the graphics pipeline in primitive order. Primitive order is initially determined in the following way:

Submission order determines the initial ordering
For indirect drawing commands, the order in which accessed instances of the VkDrawIndirectCommand are stored in buffer, from lower indirect buffer addresses to higher addresses.
If a drawing command includes multiple instances, the order in which instances are executed, from lower numbered instances to higher.
The order in which primitives are specified by a drawing command:
- For non-indexed draws, from vertices with a lower numbered vertexIndex to a higher numbered vertexIndex.
- For indexed draws, vertices sourced from a lower index buffer addresses to higher addresses.

Within this order implementations further sort primitives:

If tessellation shading is active, by an implementation-dependent order of new primitives generated by tessellation.
If geometry shading is active, by the order new primitives are generated by geometry shading.
If the polygon mode is not VK_POLYGON_MODE_FILL, by an implementation-dependent ordering of the new primitives generated within the original primitive.

Primitive order is later used to define rasterization order, which determines the order in which fragments output results to a framebuffer.

20.3. Programmable Primitive Shading

Once primitives are assembled, they proceed to the vertex shading stage of the pipeline. If the draw includes multiple instances, then the set of primitives is sent to the vertex shading stage multiple times, once for each instance.

It is implementation-dependent whether vertex shading occurs on vertices that are discarded as part of incomplete primitives, but if it does occur then it operates as if they were vertices in complete primitives and such invocations can have side effects.

Vertex shading receives two per-vertex inputs from the primitive assembly stage - the vertexIndex and the instanceIndex. How these values are generated is defined below, with each command.

Drawing commands fall roughly into two categories:

Non-indexed drawing commands present a sequential vertexIndex to the vertex shader. The sequential index is generated automatically by the device (see Fixed-Function Vertex Processing for details on both specifying the vertex attributes indexed by vertexIndex, as well as binding vertex buffers containing those attributes to a command buffer). These commands are:
Indexed drawing commands read index values from an index buffer and use this to compute the vertexIndex value for the vertex shader. These commands are:

To bind an index buffer to a command buffer, call:

// Provided by VK_VERSION_1_0
void vkCmdBindIndexBuffer(
    VkCommandBuffer                             commandBuffer,
    VkBuffer                                    buffer,
    VkDeviceSize                                offset,
    VkIndexType                                 indexType);

commandBuffer is the command buffer into which the command is recorded.
buffer is the buffer being bound.
offset is the starting offset in bytes within buffer used in index buffer address calculations.
indexType is a VkIndexType value specifying the size of the indices.

Possible values of vkCmdBindIndexBuffer::indexType, specifying the size of indices, are:

// Provided by VK_VERSION_1_0
typedef enum VkIndexType {
    VK_INDEX_TYPE_UINT16 = 0,
    VK_INDEX_TYPE_UINT32 = 1,
} VkIndexType;

VK_INDEX_TYPE_UINT16 specifies that indices are 16-bit unsigned integer values.
VK_INDEX_TYPE_UINT32 specifies that indices are 32-bit unsigned integer values.

The parameters for each drawing command are specified directly in the command or read from buffer memory, depending on the command. Drawing commands that source their parameters from buffer memory are known as indirect drawing commands.

All drawing commands interact with the robustBufferAccess feature.

To record a non-indexed draw, call:

// Provided by VK_VERSION_1_0
void vkCmdDraw(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    vertexCount,
    uint32_t                                    instanceCount,
    uint32_t                                    firstVertex,
    uint32_t                                    firstInstance);

commandBuffer is the command buffer into which the command is recorded.
vertexCount is the number of vertices to draw.
instanceCount is the number of instances to draw.
firstVertex is the index of the first vertex to draw.
firstInstance is the instance ID of the first instance to draw.

When the command is executed, primitives are assembled using the current primitive topology and vertexCount consecutive vertex indices with the first vertexIndex value equal to firstVertex. The primitives are drawn instanceCount times with instanceIndex starting with firstInstance and increasing sequentially for each instance. The assembled primitives execute the bound graphics pipeline.

void vkCmdDrawIndexed(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    indexCount,
    uint32_t                                    instanceCount,

    uint32_t                                    firstInstance);

commandBuffer is the command buffer into which the command is recorded.
indexCount is the number of vertices to draw.
instanceCount is the number of instances to draw.
firstIndex is the base index within the index buffer.
vertexOffset is the value added to the vertex index before indexing into the vertex buffer.
firstInstance is the instance ID of the first instance to draw.

When the command is executed, primitives are assembled using the current primitive topology and indexCount vertices whose indices are retrieved from the index buffer. The index buffer is treated as an array of tightly packed unsigned integers of size defined by the vkCmdBindIndexBuffer::indexType parameter with which the buffer was bound.

The first vertex index is at an offset of firstIndex × indexSize + offset within the bound index buffer, where offset is the offset specified by vkCmdBindIndexBuffer and indexSize is the byte size of the type specified by indexType. Subsequent index values are retrieved from consecutive locations in the index buffer. Indices are first compared to the primitive restart value, then zero extended to 32 bits (if the indexType is VK_INDEX_TYPE_UINT16) and have vertexOffset added to them, before being supplied as the vertexIndex value.

The primitives are drawn instanceCount times with instanceIndex starting with firstInstance and increasing sequentially for each instance. The assembled primitives execute the bound graphics pipeline.

To record a non-indexed indirect drawing command, call:

// Provided by VK_VERSION_1_0
void vkCmdDrawIndirect(
    VkCommandBuffer                             commandBuffer,
    VkBuffer                                    buffer,

    uint32_t                                    stride);

commandBuffer is the command buffer into which the command is recorded.
buffer is the buffer containing draw parameters.
offset is the byte offset into buffer where parameters begin.
drawCount is the number of draws to execute, and can be zero.
stride is the byte stride between successive sets of draw parameters.

vkCmdDrawIndirect behaves similarly to vkCmdDraw except that the parameters are read by the device from a buffer during execution. drawCount draws are executed by the command, with parameters taken from buffer starting at offset and increasing by stride bytes for each successive draw. The parameters of each draw are encoded in an array of VkDrawIndirectCommand structures. If drawCount is less than or equal to one, stride is ignored.

The VkDrawIndirectCommand structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkDrawIndirectCommand {
    uint32_t    vertexCount;
    uint32_t    instanceCount;
    uint32_t    firstVertex;
    uint32_t    firstInstance;
} VkDrawIndirectCommand;

vertexCount is the number of vertices to draw.
instanceCount is the number of instances to draw.
firstVertex is the index of the first vertex to draw.
firstInstance is the instance ID of the first instance to draw.

The members of VkDrawIndirectCommand have the same meaning as the similarly named parameters of vkCmdDraw.

Valid Usage

VUID-VkDrawIndirectCommand-None-00500
For a given vertex buffer binding, any attribute data fetched must be entirely contained within the corresponding vertex buffer binding, as described in Vertex Input Description
VUID-VkDrawIndirectCommand-firstInstance-00501
If the drawIndirectFirstInstance feature is not enabled, firstInstance must be 0

To record a non-indexed draw call with a draw call count sourced from a buffer, call:

// Provided by VK_VERSION_1_2
void vkCmdDrawIndirectCount(
    VkCommandBuffer                             commandBuffer,
    VkBuffer                                    buffer,
    VkDeviceSize                                offset,
    VkBuffer                                    countBuffer,
    VkDeviceSize                                countBufferOffset,
    uint32_t                                    maxDrawCount,
    uint32_t                                    stride);

commandBuffer is the command buffer into which the command is recorded.
buffer is the buffer containing draw parameters.
offset is the byte offset into buffer where parameters begin.
countBuffer is the buffer containing the draw count.
countBufferOffset is the byte offset into countBuffer where the draw count begins.
maxDrawCount specifies the maximum number of draws that will be executed. The actual number of executed draw calls is the minimum of the count specified in countBuffer and maxDrawCount.
stride is the byte stride between successive sets of draw parameters.

vkCmdDrawIndirectCount behaves similarly to vkCmdDrawIndirect except that the draw count is read by the device from a buffer during execution. The command will read an unsigned 32-bit integer from countBuffer located at countBufferOffset and use this as the draw count.

// Provided by VK_VERSION_1_0
void vkCmdDrawIndexedIndirect(
    VkCommandBuffer                             commandBuffer,
    VkBuffer                                    buffer,
    VkDeviceSize                                offset,
    uint32_t                                    drawCount,
    uint32_t                                    stride);

commandBuffer is the command buffer into which the command is recorded.
buffer is the buffer containing draw parameters.
offset is the byte offset into buffer where parameters begin.
drawCount is the number of draws to execute, and can be zero.
stride is the byte stride between successive sets of draw parameters.

vkCmdDrawIndexedIndirect behaves similarly to vkCmdDrawIndexed except that the parameters are read by the device from a buffer during execution. drawCount draws are executed by the command, with parameters taken from buffer starting at offset and increasing by stride bytes for each successive draw. The parameters of each draw are encoded in an array of VkDrawIndexedIndirectCommand structures. If drawCount is less than or equal to one, stride is ignored.

The VkDrawIndexedIndirectCommand structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkDrawIndexedIndirectCommand {
    uint32_t    indexCount;
    uint32_t    instanceCount;
    uint32_t    firstIndex;
    int32_t     vertexOffset;
    uint32_t    firstInstance;
} VkDrawIndexedIndirectCommand;

indexCount is the number of vertices to draw.
instanceCount is the number of instances to draw.
firstIndex is the base index within the index buffer.
vertexOffset is the value added to the vertex index before indexing into the vertex buffer.
firstInstance is the instance ID of the first instance to draw.

The members of VkDrawIndexedIndirectCommand have the same meaning as the similarly named parameters of vkCmdDrawIndexed.

Valid Usage

To record an indexed draw call with a draw call count sourced from a buffer, call:

// Provided by VK_VERSION_1_2
void vkCmdDrawIndexedIndirectCount(
    VkCommandBuffer                             commandBuffer,
    VkBuffer                                    buffer,
    VkDeviceSize                                offset,
    VkBuffer                                    countBuffer,
    VkDeviceSize                                countBufferOffset,
    uint32_t                                    maxDrawCount,
    uint32_t                                    stride);

commandBuffer is the command buffer into which the command is recorded.
buffer is the buffer containing draw parameters.
offset is the byte offset into buffer where parameters begin.
countBuffer is the buffer containing the draw count.
countBufferOffset is the byte offset into countBuffer where the draw count begins.
maxDrawCount specifies the maximum number of draws that will be executed. The actual number of executed draw calls is the minimum of the count specified in countBuffer and maxDrawCount.
stride is the byte stride between successive sets of draw parameters.

vkCmdDrawIndexedIndirectCount behaves similarly to vkCmdDrawIndexedIndirect except that the draw count is read by the device from a buffer during execution. The command will read an unsigned 32-bit integer from countBuffer located at countBufferOffset and use this as the draw count.
