3D-object loader

This is an Java object loader applications to *.obj files.
it is a well know code to load teabot.obj or any other .obj file as a 3D- object

To run the file you must do the following :
1. You must have the Java3D package
if u don't have it you can download is from this link :


2.Compile the Following file :
java code
