C Specification

The primitive topology is specified by the VkPipelineInputAssemblyStateCreateInfo::topology property of the currently active pipeline, if the pipeline was not created with VK_DYNAMIC_STATE_PRIMITIVE_TOPOLOGY_EXT enabled.

Otherwise, the primitive topology is set by calling:

// Provided by VK_EXT_extended_dynamic_state
void vkCmdSetPrimitiveTopologyEXT(
    VkCommandBuffer                             commandBuffer,
    VkPrimitiveTopology                         primitiveTopology);


  • commandBuffer is the command buffer into which the command will be recorded.

  • topology specifies the primitive topology to use for drawing.


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

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

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

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

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

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