Volumetric scattering is proposed for v1.0. To implement it requires a complete re-implementation of the volume integration system. This would be a significant API change and would require cherab's materials to be rewritten. See #357.
Dear Raysect team,
currently rays fired by observers are of rectilinear trajectory, which could potentially be reflected/scattered by material surfaces (call it "superficial scattering").
Adding "volumetric scattering", i.e. simulating non-rectilinear ray trajectories within the volume of a material, could potentially be interesting. The scattering probability would generally depend on local material properties, specified by the user via a
scattering_function_3d()
. If material properties vary in space, then relying on adaptive integration (see this issue) would be a necessary conditon.Quoting the wise strategy suggested by @vsnever (from this issue):
What do you think? Thank you! Cheers, Matteo
