C Specification
Acceleration structure motion instances can be built into top-level acceleration structures. Each acceleration structure instance is a separate entry in the top-level acceleration structure which includes all the geometry of a bottom-level acceleration structure at a transformed location including a type of motion and parameters to determine the motion of the instance over time.
An acceleration structure motion instance is defined by the structure:
// Provided by VK_NV_ray_tracing_motion_blur
typedef struct VkAccelerationStructureMotionInstanceNV {
VkAccelerationStructureMotionInstanceTypeNV type;
VkAccelerationStructureMotionInstanceFlagsNV flags;
VkAccelerationStructureMotionInstanceDataNV data;
} VkAccelerationStructureMotionInstanceNV;Members
-
typeis a VkAccelerationStructureMotionInstanceTypeNV enumerant identifying which type of motion instance this is and which type of the union is valid. -
flagsis currently unused, but is required to keep natural alignment ofdata. -
datais a VkAccelerationStructureMotionInstanceDataNV containing motion instance data for this instance.

If writing this other than with a standard C compiler, note that the final structure should be 152 bytes in size. |
