#procedural-mesh

A decimated heightfield mesher renders carved cliffs as alternating sawtooth teeth; consistent diagonals and majority-vote corner snapping don't fix the crest. Sort the four corner samples, find the largest gap, and average only the cluster above it.

A voxel/heightfield world usually carries two surfaces: a fine render mesh and a coarser collision heightfield. Procedural character-facing geometry (climb grips, standoff nodes) must be sampled from the collision surface, or it floats off the real face the character actually touches.
