--
-- == Description
--
-- 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 'AccelerationStructureGeometryMotionTrianglesDataNV' and
-- providing multiple transforms in the instance using
-- 'AccelerationStructureMotionInstanceNV'.

-- == Issues
--
-- (1) What size is VkAccelerationStructureMotionInstanceNV?
--
-- -   Added a note on the structure size and made the stride explicit in
--     the language.
--
-- (2) Allow arrayOfPointers for motion TLAS?
--
-- -   Yes, with a packed encoding to minimize the amount of data sent for
--     metadata.
