objtools contains tools to operate on SGO objects
SGO format is useful for representing 3D geometry. Each SGO object
is either a list of quadrilaterals, a list of triangles, or a list of
triangle meshes. The programs provided here provide various tools
for operating on these objects. These tools use various functions
from libgutil that support a simplified interface to describe
shading, automatic triangle mesh generation and efficient drawing
of geometry.

in a triangle or quadralateral object
