C Specification

To dynamically set primitive topology, call:

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

or the equivalent command

// Provided by VK_EXT_extended_dynamic_state, VK_EXT_shader_object
void vkCmdSetPrimitiveTopologyEXT(
    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 drawing using shader objects, or 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
  • VUID-vkCmdSetPrimitiveTopology-None-08971
    At least one of the following must be true:

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

  • VUID-vkCmdSetPrimitiveTopology-primitiveTopology-parameter
    primitiveTopology must be a valid VkPrimitiveTopology value

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

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

  • VUID-vkCmdSetPrimitiveTopology-videocoding
    This command must only be called outside of a video coding scope

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

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