C Specification

To dynamically set the rasterizationStream state, call:

// Provided by VK_EXT_extended_dynamic_state3 with VK_EXT_transform_feedback, VK_EXT_shader_object with VK_EXT_transform_feedback
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
