3D Object reader and Mesh Decimator

.obj file reader and Mesh Decimator created as a final project for CS 4300 Computer Graphics

• This project implements the Edge Collapse algorithm for mesh decimation.

See Demo: https://www.youtube.com/watch?v=onctVXrx-0s

How to run

1. Python, OpenGL, and SDL are required to run
2. Navigate to ./ModelParserAndDecimator/part1 and in the terminal run python3 build.py
3. Then from the terminal run ./lab to run the executable.
4. A SDL window will pop up and display a mesh, allowing decimation functionality. See the window commands below.

Commands

1. Press w to toggle wireframe mode
2. Press number keys to decimate mesh by a percentage * 1 is 10%, 2 is 20%, and so on * 0 is 99%
3. Press spacebar to switch to a new model
