C Specification

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);

Parameters

  • 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.

Description

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.

    An index buffer must be bound

  • VUID-vkCmdDrawIndexedIndirectCount-robustBufferAccess2-07825
    If robustBufferAccess2 is not enabled, (indexSize × (firstIndex + indexCount) + offset) must be less than or equal to the size of the bound index buffer, with indexSize being based on the type specified by indexType, where the index buffer, indexType, and offset are specified via vkCmdBindIndexBuffer

  • VUID-vkCmdDrawIndexedIndirectCount-stride-03142
    stride must be a multiple of 4 and must be greater than or equal to sizeof(VkDrawIndexedIndirectCommand)

  • VUID-vkCmdDrawIndexedIndirectCount-maxDrawCount-03143
    If maxDrawCount is greater than or equal to 1, (stride × (maxDrawCount - 1) + offset + sizeof(VkDrawIndexedIndirectCommand)) must be less than or equal to the size of buffer

  • VUID-vkCmdDrawIndexedIndirectCount-countBuffer-03153
    If count stored in countBuffer is equal to 1, (offset + sizeof(VkDrawIndexedIndirectCommand)) must be less than or equal to the size of buffer

  • VUID-vkCmdDrawIndexedIndirectCount-countBuffer-03154
    If count stored in countBuffer is greater than 1, (stride × (drawCount - 1) + offset + sizeof(VkDrawIndexedIndirectCommand)) must be less than or equal to the size of buffer

Valid Usage (Implicit)
  • VUID-vkCmdDrawIndexedIndirectCount-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdDrawIndexedIndirectCount-buffer-parameter
    buffer must be a valid VkBuffer handle

  • VUID-vkCmdDrawIndexedIndirectCount-countBuffer-parameter
    countBuffer must be a valid VkBuffer handle

  • VUID-vkCmdDrawIndexedIndirectCount-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdDrawIndexedIndirectCount-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics operations

  • VUID-vkCmdDrawIndexedIndirectCount-renderpass
    This command must only be called inside of a render pass instance

  • VUID-vkCmdDrawIndexedIndirectCount-commonparent
    Each of buffer, commandBuffer, and countBuffer must have been created, allocated, or retrieved from the same VkDevice

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
