Editing Glome (section)

==GlomeTrace==
GlomeTrace is a library that provides ray-tracing algorithms and a variety of geometry primitives.  Originally, it was part of Glome, but now it is a stand-alone library.

Supported base primitives include: sphere, triangle, cone, cylinder, disc, plane, and box.

Composite primitives (those which are containers for other primitives) include groups, csg differenc and intersection, transformed instances, textured objects, and bounding objects.

In addition, there is an implementation of the BIH acceleration structure, which automatically builds a bounding volume hierarchy around unsorted lists of primitives.  This greatly improves the performance for large scenes.

GlomeTrace depends on GlomeVec, but it doesn't have any other unusual dependencies.
