# vkCmdSetPrimitiveTopologyEXT(3) Manual Page

## Name

vkCmdSetPrimitiveTopologyEXT - Set the primitive topology state

Loading… please wait.

## 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);

## Parameters

- `commandBuffer` is the command buffer into which the command will be recorded.

- `topology` specifies the primitive topology to use for drawing.

## Description

Valid Usage

- VUID-vkCmdSetPrimitiveTopologyEXT-None-03347
  The extendedDynamicState feature must be enabled

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

Command Properties

Command Buffer Levels | Render Pass Scope | Supported Queue Types | Pipeline Type
--- | --- | --- | ---
Primary Secondary | Both | Graphics |
