vkCmdSetRasterizationStreamEXT(3)

C Specification

To dynamically set the rasterizationStream state, call:

// Provided by VK_EXT_extended_dynamic_state3, VK_EXT_shader_object
void vkCmdSetRasterizationStreamEXT(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    rasterizationStream);

Parameters

commandBuffer is the command buffer into which the command will be recorded.
rasterizationStream specifies the rasterizationStream state.

Description

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-08550
Either the extendedDynamicState3RasterizationStream feature or the shaderObject feature or both must be enabled
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
