C Specification

The VkGeometryNV structure describes geometry in a bottom-level acceleration structure and is defined as:

// Provided by VK_NV_ray_tracing
typedef struct VkGeometryNV {
    VkStructureType       sType;
    const void*           pNext;
    VkGeometryTypeKHR     geometryType;
    VkGeometryDataNV      geometry;
    VkGeometryFlagsKHR    flags;
} VkGeometryNV;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • geometryType specifies the VkGeometryTypeKHR which this geometry refers to.

  • geometry contains the geometry data as described in VkGeometryDataNV.

  • flags has VkGeometryFlagBitsKHR describing options for this geometry.

Description

Valid Usage

  • VUID-VkGeometryNV-geometryType-03503
    geometryType must be VK_GEOMETRY_TYPE_TRIANGLES_NV or VK_GEOMETRY_TYPE_AABBS_NV

Valid Usage (Implicit)

  • VUID-VkGeometryNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_GEOMETRY_NV

  • VUID-VkGeometryNV-pNext-pNext
    pNext must be NULL

  • VUID-VkGeometryNV-geometryType-parameter
    geometryType must be a valid VkGeometryTypeKHR value

  • VUID-VkGeometryNV-geometry-parameter
    geometry must be a valid VkGeometryDataNV structure

  • VUID-VkGeometryNV-flags-parameter
    flags must be a valid combination of VkGeometryFlagBitsKHR values
