Function Documentation

◆ gsd_coarse_surf_map()

int gsd_coarse_surf_map ( geosurf surf)

Draw coarse surface.

New (TEST) wire routine that draws low res surface Based on new Trinagle Fan routine Resolution is a function of current surface resolution times wire resolution

Todo:
normals have to be recalculated before proper low res surface can be drawn

In window optimization has been removed
