LWJGL 3.3.3 · org.lwjgl.vulkan.NVRayTracingMotionBlur

Ray tracing support in the API provides an efficient mechanism to intersect rays against static geometry, but rendering algorithms often want to support motion, which is more efficiently supported with motion-specific algorithms. This extension adds a set of mechanisms to support fast tracing of moving geometry:

A ray pipeline trace call which takes a time parameter
Flags to enable motion support in an acceleration structure
Support for time-varying vertex positions in a geometry
Motion instances to move existing instances over time

The motion represented here is parameterized across a normalized timestep between 0.0 and 1.0. A motion trace using OpTraceRayMotionNV provides a time within that normalized range to be used when intersecting that ray with geometry. The geometry can be provided with motion by a combination of adding a second vertex position for time of 1.0 using VkAccelerationStructureGeometryMotionTrianglesDataNV and providing multiple transforms in the instance using VkAccelerationStructureMotionInstanceNV.
