PolyVox improvements in code review


We are continuing the work on PolyVox and there is a PR up for review with some updates: https://github.com/highfidelity/hifi/pull/5706

The details of the update are:

  • PolyVox marching-cube entites can be stitched together so they make a continuous surface.
  • PolyVox setCuboid allows setting a rectangular region.
  • voxel.js supports setting / clearing “spheres” of voxels again.
  • Normals on PolyVoxs are now more correct.
  • Various PolyVox related bug-fixes.
