## Name

VkAccelerationStructureGeometryDataKHR - Union specifying acceleration structure geometry data

Loading… please wait.

## C Specification

The `VkAccelerationStructureGeometryDataKHR` union is defined as:

    // Provided by VK_KHR_acceleration_structure
    typedef union VkAccelerationStructureGeometryDataKHR {
        VkAccelerationStructureGeometryTrianglesDataKHR    triangles;
        VkAccelerationStructureGeometryAabbsDataKHR        aabbs;
        VkAccelerationStructureGeometryInstancesDataKHR    instances;
    } VkAccelerationStructureGeometryDataKHR;

## Members

- `triangles` is a VkAccelerationStructureGeometryTrianglesDataKHR structure.

- `aabbs` is a VkAccelerationStructureGeometryAabbsDataKHR structure.

- `instances` is a VkAccelerationStructureGeometryInstancesDataKHR structure.
