All the program source files for the lab for CSO-351.

Computer Graphics

This directory contains all the relevant lab programs from the course Computer Graphics. This is meant to serve an a beginner's guide to OpenGL in C++ and implement the standard Graphic processing and rendering algorithms. You can find the screenshots of running all the binaries in the images directory.

About the repository structure

All the source code files are located in the programs directory, and the root level binaries directory is for the complied binaries generated from the source code.

To compile a source code file, use the following command:

g++ programs/FileName.cpp -o binaries/FileName -lglut -lGLU -lGL

This will create a file called FileName in the binaries directory. You can execute the same by executing the following:

./binaries/FileName

For the purposes of this repository, I would not be commiting the binaries folder.

Compiling all the binaries

You can compile all the binaries in one go by using the shell script.

chmod +x compile.sh
./compile.sh
