class Geo::GeoEmbreeContext

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

An IGeoRayTracingContext that implements the Intel Embree raytracer.

Note
titleNote

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.
