class Geo::GeoEmbreeContext

└>Geo::IGeoRayTracingContext
└>Geo::IGeoReleasable

An IGeoRayTracingContext that implements the Intel Embree raytracer.

Note

Enlighten changes

We have changed the GeoEmbreecontext create and raytrace function implementation using Intel Embree 3.11.
We do not change the implementation of backfacing triangle and Level of Detail filtering.
Level of Detail filtering (required for baking) is only implemented in the Plücker Triangle4v Intersector, other paths are unavailable.
Prevent the TaskScheduler from being allocated at program initialisation, so we control when it uses memory.
