OptionalresolutionDepth-buffer resolution along the longer (u, v) axis of
the projection plane (the shorter axis is scaled to match
the AABB aspect). Default 2048. Higher gives finer
occlusion boundaries at proportionally higher build cost.
OptionalsamplesNumber of points sampled along each edge for the
visibility test. Default 5. Higher catches edges that
cross visibility boundaries between samples; lower is
faster.
OptionaltoleranceDepth-bias tolerance, in world units. An edge sample is
considered visible when its depth is within this much of
the buffer depth. Default 0.01 (1 cm) — large enough to
keep crease edges of the model itself from self-occluding
under floating-point noise, small enough that real
occluders still hide what they should.
Tuning parameters for hidden-line elimination. All optional; defaults work well for typical BIM geometry.
