glitter OpenGL Iterative Tutorial Tasks on Efficient Rendering

About

glitter is composed of tutorial tasks designed to build a lightweight OpenGL API. It is written in C++ and runs on Linux, and Mac OS. It provides a foundation for the homework assignments in the course titled Bases of Image Synthesis taught at ENSICAEN. The framework is inspired by NORI, a ray tracer originally designed by Wenzel Jakob for tutorials at ETH Zürich.

While glitter provides much support code to simplify your development work as much as possible, the code that you will initially receive from us does very little: it initializes an openGL context and launches a main loop. What is lacking is the actual OpenGL routine calls (state variable, and openGL settings, draw call, etc.).

Your task will precisely be to extend this system to a full-fledged OpenGL renderer as part of programming assignments and your final project. To do so, you are going to implement classes that are very simple facades to basic OpenGL objects (Buffers, VAO, Shaders, ...). More sophisticated abstraction have been discarded on purpose for pedagogical reasons.

Core features

The glitter base code provides a few features that would be tedious to implement from scratch. The following features are included:

• Window management and context initialization (glfw)
• OpenGL entrypoints loading library (glew)
• Basic matrix vector algebra (glm)
• A loader for Wavefront OBJ files (tinyobjloader)
