lawnjelly	512b0f16a3	Tight shadow culling - increase epsilon to prevent flickering ... Near colinear triangles were still causing inaccuracy in culling planes, so the threshold for colinearity is bumped up.	2024-05-18 14:14:27 +01:00
lawnjelly	70cd25f3eb	Tighter shadow culling - fix light colinear to frustum edge ... In rare situations if a light is placed near colinear to a frustum edge, the extra culling plane derived can have an inaccurate normal due to floating point error. This PR detects colinear triangles, and prevents adding a culling plane in this situation.	2024-03-20 16:47:54 +00:00
lawnjelly	4577dfdb67	Shadow volume culling and tighter shadow caster culling ... Existing shadow caster culling takes no account of the camera. This PR adds the highly encapsulated class RenderingLightCuller which can cut down the casters in the shadow volume to only those which can cast shadows on the camera frustum.	2024-01-30 08:38:31 +00:00
