class Geo GeoEmbreeContext
class Geo::GeoEmbreeContext
  └>Geo::IGeoRayTracingContext
    └>Geo::IGeoReleasable
An IGeoRayTracingContext that implements the Intel Embree raytracer.
Note
Enlighten changes
We have removed the SSSE3 and SSE3 instructions from the common/simd header files. This breaks the bvh2 path completely (missing shuffle8 instruction).
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.
