COMP3320 OpenGL Tutorials

This repository contains some example code for using OpenGL in a C++ environment using a CMake build system.

This code is heavily based on the tutorials provided at learnopengl.com.

Getting Started

https://learnopengl.com/

  1. Build 3rdparty dependencies
mkdir 3rdparty/build
cd 3rdparty/build
cmake ..
make
cd ../../
  1. Build the examples
mkdir build
cd build
cmake ..
make
  1. Run the examples (from the build folder)
./bin/movement
