--------------------------------------------------------

This archive contains 5 source code files that implements a
ray tracer with lightweight bounding volumes:

	Geometry.h, Geometry.cpp, LBVH.h, LBVH.cpp and lbvhTrace.cpp. 

The LBVH implementation is contained in LBVH.h and LBVH.cpp.
The other source files are supporting code for the lbvhTrace.cpp
main program.

The archive also contains three example scenes:

	bunnyScene.txt, bunnies.txt and buddha.txt
	
as well as thumbnails of the scenes in jpeg format.
The scenes reference .ply files of the Stanford bunny
and happy buddha, available from the Stanford 3D scanning
repository:

	http://graphics.stanford.edu/data/3Dscanrep/

Also note that the parsing capabilities of the ray tracer
are extremely limited.
