Implementation of catmull-clark subdivsion for quads

This program provides an implementation of Catmull-Clark's quad subdivision algorithm which is used to transform a continues quadmesh into a "smoother mesh".

USING THE PROGRAM:

This program uses JOGL, a java wrapper for openGL, to display the final mesh. As such this project must be compiled with the dependency jars within the "lib" folder.

For simplicity I have included an executable jar file that allows the program to be run from the command line.

The usage is as follows: java -jar Subdivider.jar infile [-subdivisions divisions] [-outfile outfile] [-show]

where: infile: is the file that contains the initial data -subdivisions: the number of times to subdivide the original mesh, where a value of 0 is no subdivisions -outfile: the file to write the newly subdivided mesh. Note: this file must not already exist. -show: if specified, the final mesh will show in a window, where the user can view the new mesh.

WHAT THIS PROGRAM IS CAPABLE OF: This program requires an input mesh's vertices to be in the form where each line in the file holds the vertices of a quad where every value is separated by spaces

Further the program will write out the data in the same way, with the inclusion of generated normals

For simplicity I have included 2 test files Cube.txt and Test.txt who define the mesh for a Cube and a T shape respectively.
