FS#8 - Improve Radiosity "Cross-Talk" Rejection in Corners

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.

Christoph, I boldly assume this has been improved with all your radiosity changes?

No, even in its current state Radiosity still offers room for improvement. I don’t intend to address it prior to the 3.7.0 release proper though.

Now tracked on github as issue #249.
