Detailed Description

template<class Calculator>
class celeritas::optical::EnteringSurfaceNormalSampler< Calculator >

Sample a valid facet normal by wrapping a roughness calculator.

Some facet normal calculators might not produce surface normals valid for optical physics surface crossings (see is_entering_surface ). This functor will construct and repeatedly sample the distribution until the track is exiting the sampled facet normal.
