public class VkAccelerationStructureBuildRangeInfoKHR
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure specifying build offsets and counts for acceleration structure builds.
Description

The primitive count and primitive offset are interpreted differently depending on the VkGeometryTypeKHR used:
- For geometries of type GEOMETRY_TYPE_TRIANGLES_KHR, primitiveCount is the number of triangles to be built, where each triangle is treated as 3 vertices.
  - If the geometry uses indices, primitiveCount × 3 indices are consumed from VkAccelerationStructureGeometryTrianglesDataKHR::indexData, starting at an offset of primitiveOffset. The value of firstVertex is added to the index values before fetching vertices.
  - If the geometry does not use indices, primitiveCount × 3 vertices are consumed from VkAccelerationStructureGeometryTrianglesDataKHR::vertexData, starting at an offset of primitiveOffset + VkAccelerationStructureGeometryTrianglesDataKHR::vertexStride × firstVertex.
  - If VkAccelerationStructureGeometryTrianglesDataKHR::transformData is not NULL, a single VkTransformMatrixKHR structure is consumed from VkAccelerationStructureGeometryTrianglesDataKHR::transformData, at an offset of transformOffset. This matrix describes a transformation from the space in which the vertices for all triangles in this geometry are described to the space in which the acceleration structure is defined.
- For geometries of type GEOMETRY_TYPE_AABBS_KHR, primitiveCount is the number of axis-aligned bounding boxes. primitiveCount VkAabbPositionsKHR structures are consumed from VkAccelerationStructureGeometryAabbsDataKHR::data, starting at an offset of primitiveOffset.
- For geometries of type GEOMETRY_TYPE_INSTANCES_KHR, primitiveCount is the number of acceleration structures. primitiveCount VkAccelerationStructureInstanceKHR or VkAccelerationStructureMotionInstanceNV structures are consumed from VkAccelerationStructureGeometryInstancesDataKHR::data, starting at an offset of primitiveOffset.
Valid Usage
- For geometries of type GEOMETRY_TYPE_TRIANGLES_KHR, if the geometry uses indices, the offset primitiveOffset from VkAccelerationStructureGeometryTrianglesDataKHR::indexData must be a multiple of the element size of VkAccelerationStructureGeometryTrianglesDataKHR::indexType
- For geometries of type GEOMETRY_TYPE_TRIANGLES_KHR, if the geometry does not use indices, the offset primitiveOffset from VkAccelerationStructureGeometryTrianglesDataKHR::vertexData must be a multiple of the component size of VkAccelerationStructureGeometryTrianglesDataKHR::vertexFormat
- For geometries of type GEOMETRY_TYPE_TRIANGLES_KHR, the offset transformOffset from VkAccelerationStructureGeometryTrianglesDataKHR::transformData must be a multiple of 16
- For geometries of type GEOMETRY_TYPE_AABBS_KHR, the offset primitiveOffset from VkAccelerationStructureGeometryAabbsDataKHR::data must be a multiple of 8
- For geometries of type GEOMETRY_TYPE_INSTANCES_KHR, the offset primitiveOffset from VkAccelerationStructureGeometryInstancesDataKHR::data must be a multiple of 16
