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 Triangle 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

Parameters

surf	surface (geosurf)

Returns
