FP3D was my undergraduate final year project. It's a strange combination of a realtime 3D graphics engine and a raytracing library. The core part of the project is a reusable library, which provides methods to set up a 3D scene either by programmatically generating primitives or by importing an OBJ file (basic models only). The scene can then be rendered using a realtime OpenGL-based renderer or a more complex raytracer.

The main challege I set myself for this project was to use as few external libraries as possible, so that I would have to learn the nitty-gritty details of several 3D graphics technologies and tools. The whole project uses only 3 external tools: GLAD for loading OpenGL function pointers, GLFW for creating the OpenGL demo window and wxWidgets for the GUI of the raytracing demo. This was good for giving me a low-level understanding of the techniques I used, but the final product is, by consequence, fairly useless: everything FP3D does can be done better by existing tools.

Being an undergraduate project, this is not exactly the most elegant or well-designed program ever. Although I enjoyed writing it, FP3D was only meant as an exercise and a playground in 3D graphics, not for any kind of real-world use.
