C Specification

The custom sample locations used for rasterization when VkPipelineSampleLocationsStateCreateInfoEXT::sampleLocationsEnable is VK_TRUE are specified by the VkPipelineSampleLocationsStateCreateInfoEXT::sampleLocationsInfo property of the bound graphics pipeline, if the pipeline was not created with VK_DYNAMIC_STATE_SAMPLE_LOCATIONS_EXT enabled.

Otherwise, the sample locations used for rasterization are set by calling vkCmdSetSampleLocationsEXT:

void vkCmdSetSampleLocationsEXT(
    VkCommandBuffer                             commandBuffer,
    const VkSampleLocationsInfoEXT*             pSampleLocationsInfo);


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

  • pSampleLocationsInfo is the sample locations state to set.


Valid Usage
  • The sampleLocationsPerPixel member of pSampleLocationsInfo must equal the rasterizationSamples member of the VkPipelineMultisampleStateCreateInfo structure the bound graphics pipeline has been created with

  • If VkPhysicalDeviceSampleLocationsPropertiesEXT::variableSampleLocations is VK_FALSE then the current render pass must have been begun by specifying a VkRenderPassSampleLocationsBeginInfoEXT structure whose pPostSubpassSampleLocations member contains an element with a subpassIndex matching the current subpass index and the sampleLocationsInfo member of that element must match the sample locations state pointed to by pSampleLocationsInfo

Valid Usage (Implicit)
  • commandBuffer must be a valid VkCommandBuffer handle

  • pSampleLocationsInfo must be a valid pointer to a valid VkSampleLocationsInfoEXT structure

  • commandBuffer must be in the recording state

  • 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
