vkCmdSetRasterizationStreamEXT

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

To dynamically set the rasterizationStream state, call:

void vkCmdSetRasterizationStreamEXT(
    VkCommandBuffer commandBuffer,
    uint32_t rasterizationStream);
  • commandBuffer is the command buffer into which the command will be recorded.
  • rasterizationStream specifies the rasterizationStream state.

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

Valid Usage

VUID-vkCmdSetRasterizationStreamEXT-None-09423

At least one of the following must be true:

VUID-vkCmdSetRasterizationStreamEXT-transformFeedback-07411

The transformFeedback feature must be enabled

VUID-vkCmdSetRasterizationStreamEXT-rasterizationStream-07412

rasterizationStream must be less than VkPhysicalDeviceTransformFeedbackPropertiesEXT::maxTransformFeedbackStreams

VUID-vkCmdSetRasterizationStreamEXT-rasterizationStream-07413

rasterizationStream must be zero if VkPhysicalDeviceTransformFeedbackPropertiesEXT::transformFeedbackRasterizationStreamSelect is VK_FALSE

::

Valid Usage (Implicit)

VUID-vkCmdSetRasterizationStreamEXT-commandBuffer-parameter

commandBuffer must be a valid VkCommandBuffer handle

VUID-vkCmdSetRasterizationStreamEXT-commandBuffer-recording

commandBuffer must be in the recording state

VUID-vkCmdSetRasterizationStreamEXT-commandBuffer-cmdpool

The VkCommandPool that commandBuffer was allocated from must support graphics operations

VUID-vkCmdSetRasterizationStreamEXT-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 ::
