8RadiosityUnimp. Feature/TODO3.70 beta 32DeferLowImprove Radiosity "Cross-Talk" Rejection in CornersTracked on GitHub
0%
Future release Task Description

Near concave edges, radiosity samples may be re-used at a longer distance away from the edge than towards the edge; there is code in place to ensure this, but it only works properly where two surfaces meet roughly rectangularly, while failing near the junction of three surfaces or non-rectangular edges, potentially causing “cross-talk”.

It should be investigated how the algorithm can be improved or replaced to better cope with non-trivial geometry.

Future release Task Description

Subsurface scattering must be made photon-aware.

4Subsurface ScatteringUnimp. Feature/TODO3.70 beta 32Very LowLowIntegrate Subsurface Scattering with standard lighting ...Tracked on GitHub
90%
Future release Task Description

Subsurface Scattering still uses its own rudimentary code to compute illumination from classic light sources; this must be changed to use the standard light source & shadow handling code, to add support for non-trivial light sources (e.g. spotlights, cylindrical lights, area lights), partially-transparent shadowing objects etc.
