OBJ2OPENGL Convert OBJ file to OpenGL format

OBJ2OPENGL?is a PERL script that reads an OBJ file describing a 3D object,and writes a C include file describing the object in a form suitable for use with Open GL.

To see how to use the include file created by this program,refer to the example in the?Open GL examples?directory.

The author wishes to point out that this script was developed for a specific purpose,and was not intended to be able to handle all variations of the OBJ file format.

Source Code:

Files you may copy include (for some loopy security reason,we must avoid the "PL" extension on the source code as distributed here:

• obj2opengl.perl,the source code (your copy will have a "PERL" extension,which you will probably want to change back to "pl");
• graphicsDefs.h,an include file that will be needed when the C file is compiled;

Examples and Tests:

CUBE?is a simple cube. Files you may copy include:

• cube.obj,an?OBJ file?of the shape;
• cube.h,the corresponding INCLUDE file created by obj2opengl.pl;

GOURD?is a complicated shape that represents a gourd. Files you may copy include:

• gourd.obj,an?OBJ file?of the shape;
• gourd.h,the corresponding INCLUDE file created by obj2opengl.pl;
