vkCmdSetRasterizationSamplesEXT

Specify the rasterization samples dynamically for a command buffer
primary / secondary
both
graphics
state

To dynamically set the rasterizationSamples, call:

void vkCmdSetRasterizationSamplesEXT(
    VkCommandBuffer commandBuffer,
    VkSampleCountFlagBits  rasterizationSamples);
  • commandBuffer is the command buffer into which the command will be recorded.
  • rasterizationSamples specifies rasterizationSamples.

This command sets the rasterizationSamples for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_RASTERIZATION_SAMPLES_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineMultisampleStateCreateInfo::rasterizationSamples value used to create the currently active pipeline.

Valid Usage

VUID-vkCmdSetRasterizationSamplesEXT-None-09423

At least one of the following must be true:

Valid Usage (Implicit)

VUID-vkCmdSetRasterizationSamplesEXT-commandBuffer-parameter

commandBuffer must be a valid VkCommandBuffer handle

VUID-vkCmdSetRasterizationSamplesEXT-rasterizationSamples-parameter

rasterizationSamples must be a valid VkSampleCountFlagBits value

VUID-vkCmdSetRasterizationSamplesEXT-commandBuffer-recording

commandBuffer must be in the recording state

VUID-vkCmdSetRasterizationSamplesEXT-commandBuffer-cmdpool

The VkCommandPool that commandBuffer was allocated from must support graphics operations

VUID-vkCmdSetRasterizationSamplesEXT-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 ::
