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.
