C Specification

The VkAccelerationStructureGeometryTrianglesDataKHR structure is defined as:

// Provided by VK_KHR_ray_tracing
typedef struct VkAccelerationStructureGeometryTrianglesDataKHR {
    VkStructureType                  sType;
    const void*                      pNext;
    VkFormat                         vertexFormat;
    VkDeviceOrHostAddressConstKHR    vertexData;
    VkDeviceSize                     vertexStride;
    VkIndexType                      indexType;
    VkDeviceOrHostAddressConstKHR    indexData;
    VkDeviceOrHostAddressConstKHR    transformData;
} VkAccelerationStructureGeometryTrianglesDataKHR;

Members

  • sType is the type of this structure.

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

  • vertexFormat is the VkFormat of each vertex element.

  • vertexData is a device or host address to memory containing vertex data for this geometry.

  • vertexStride is the stride in bytes between each vertex.

  • indexType is the VkIndexType of each index element.

  • indexData is a device or host address to memory containing index data for this geometry.

  • transformData is a device or host address to memory containing an optional reference to a VkTransformMatrixKHR structure defining a transformation that should be applied to vertices in this geometry.

Description

Valid Usage
