## Name

VkGeometryNV - Structure specifying a geometry in a bottom-level acceleration structure

Loading… please wait.

## 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
