## Name

VkGeometryTypeKHR - Enum specifying which type of geometry is provided

Loading… please wait.

## C Specification

Geometry types are specified by VkGeometryTypeKHR, which takes values:

    // Provided by VK_KHR_acceleration_structure
    typedef enum VkGeometryTypeKHR {
        VK_GEOMETRY_TYPE_TRIANGLES_KHR = 0,
        VK_GEOMETRY_TYPE_AABBS_KHR = 1,
        VK_GEOMETRY_TYPE_INSTANCES_KHR = 2,
      // Provided by VK_NV_ray_tracing_linear_swept_spheres
        VK_GEOMETRY_TYPE_SPHERES_NV = 1000429004,
      // Provided by VK_NV_ray_tracing_linear_swept_spheres
        VK_GEOMETRY_TYPE_LINEAR_SWEPT_SPHERES_NV = 1000429005,
      // Provided by VK_NV_ray_tracing
        VK_GEOMETRY_TYPE_TRIANGLES_NV = VK_GEOMETRY_TYPE_TRIANGLES_KHR,
      // Provided by VK_NV_ray_tracing
        VK_GEOMETRY_TYPE_AABBS_NV = VK_GEOMETRY_TYPE_AABBS_KHR,
    } VkGeometryTypeKHR;

or the equivalent

    // Provided by VK_NV_ray_tracing
    typedef VkGeometryTypeKHR VkGeometryTypeNV;

## Description

- `VK_GEOMETRY_TYPE_TRIANGLES_KHR` specifies a geometry type consisting of triangles.

- `VK_GEOMETRY_TYPE_AABBS_KHR` specifies a geometry type consisting of axis-aligned bounding boxes.

- `VK_GEOMETRY_TYPE_INSTANCES_KHR` specifies a geometry type consisting of acceleration structure instances.

- `VK_GEOMETRY_TYPE_SPHERES_NV` specifies a geometry type consisting of spheres.

- `VK_GEOMETRY_TYPE_LINEAR_SWEPT_SPHERES_NV` specifies a geometry type consisting of linear swept spheres.
