SamplerCache

The sampler of an item's loaded mesh, built once for the last few meshes (field-presentation §FVS-1, §FVS-2).

In the namespace construct::rendering. Declared in src/libs/libconstruct/construct/rendering/SamplerCache.hpp.

Detailed description

A locator of a million tets takes a few hundred milliseconds to build, so a plan of many samples, a probe table and a line probe share one. The face table comes from the asset's boundary when it is there. The cache holds the mesh, so a sampler outlives a replaced asset. Thread safe. The hover keeps its own, which refits to a deformed part.
