Our computer graphics lecturer asked us to make a walking simulation using OpenGL. This is an OpenGL 4.3 application using only low level libraries:
- GLEW for OpenGL loader
- GLFW for windowing and OpenGL context creation
- GLM for mathematics.
We didn't use game engine like Unity and whatnot. We made our own engine.
Features include: model loading using OBJ Wavefront, third-person camera, Blinn-Phong shader, walking animation, simple collision handler, nameplate rendering, and a scripting system running on a different thread.
See documentation/user/main.pdf for more information.
