groundProjection

The shader module every groundMaterials shader includes: places textures by where each point stands on its object, in metres (real size on any box, plane or model, no UVs), projects from the side a surface faces, and hex-tiles each projection (random offset and turn per cell, cells meeting by mask height) so a field never shows its repeat. Also a slow macro brightness noise. After Brick and Mortar's masonryProjection (MIT).
