VkAccelerationStructureGeometrySpheresDataNV

If VkAccelerationStructureGeometrySpheresDataNV is included in the pNext chain of a VkAccelerationStructureGeometryKHR structure, then that structures defines the sphere’s geometry data.

The VkAccelerationStructureGeometrySpheresDataNV structure is defined as:

typedef struct VkAccelerationStructureGeometrySpheresDataNV {
    VkStructureType sType;
    const void* pNext;
    VkFormat vertexFormat;
    VkDeviceOrHostAddressConstKHR vertexData;
    VkDeviceSize vertexStride;
    VkFormat radiusFormat;
    VkDeviceOrHostAddressConstKHR radiusData;
    VkDeviceSize radiusStride;
    VkIndexType indexType;
    VkDeviceOrHostAddressConstKHR indexData;
    VkDeviceSize indexStride;
} VkAccelerationStructureGeometrySpheresDataNV;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• vertexFormat is the VkFormat of each sphere’s vertex element.
• vertexData is a device or host address to memory containing vertex data in form of pairs of centers of spheres that define all sphere geometry.
• vertexStride is the stride in bytes between each vertex element.
• radiusFormat is the VkFormat of each sphere’s radius.
• radiusData is a device or host address to memory containing sphere’s radius data value.
• radiusStride is the stride in bytes between each radius value.
• indexType is the VkIndexType of each index element.
• indexData is NULL or a device or host address to memory containing index data for vertex and radius buffers for this geometry.
• indexStride is the stride in bytes between each index element.
