C Specification

The vertex stream used for rasterization is specified by adding a VkPipelineRasterizationStateStreamCreateInfoEXT structure to the pNext chain of a VkPipelineRasterizationStateCreateInfo structure.

The VkPipelineRasterizationStateStreamCreateInfoEXT structure is defined as:

// Provided by VK_EXT_transform_feedback
typedef struct VkPipelineRasterizationStateStreamCreateInfoEXT {
    VkStructureType                                     sType;
    const void*                                         pNext;
    VkPipelineRasterizationStateStreamCreateFlagsEXT    flags;
    uint32_t                                            rasterizationStream;
} VkPipelineRasterizationStateStreamCreateInfoEXT;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags is reserved for future use.

  • rasterizationStream is the vertex stream selected for rasterization.

Description

If this structure is not present, rasterizationStream is assumed to be zero.

Valid Usage

  • VUID-VkPipelineRasterizationStateStreamCreateInfoEXT-geometryStreams-02324
    VkPhysicalDeviceTransformFeedbackFeaturesEXT::geometryStreams must be enabled

  • VUID-VkPipelineRasterizationStateStreamCreateInfoEXT-rasterizationStream-02325
    rasterizationStream must be less than VkPhysicalDeviceTransformFeedbackPropertiesEXT::maxTransformFeedbackStreams

  • VUID-VkPipelineRasterizationStateStreamCreateInfoEXT-rasterizationStream-02326
    rasterizationStream must be zero if VkPhysicalDeviceTransformFeedbackPropertiesEXT::transformFeedbackRasterizationStreamSelect is VK_FALSE

Valid Usage (Implicit)

  • VUID-VkPipelineRasterizationStateStreamCreateInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_PIPELINE_RASTERIZATION_STATE_STREAM_CREATE_INFO_EXT

  • VUID-VkPipelineRasterizationStateStreamCreateInfoEXT-flags-zerobitmask
    flags must be 0
