thicknessHeuristic property

double thicknessHeuristic
getter/setter pair

How quickly a horizon decays when the march walks past an occluder, from 0.0 (horizons never decay, thin occluders over-darken) to 1.0 (each farther sample fully replaces the horizon). Small values are enough. Only used by AmbientOcclusionMethod.groundTruth when visibilityBitmask is disabled.

Implementation

double thicknessHeuristic = 0.004;
