A playground project I used to explore computer graphics with OpenGL. I had fun with it for about 8 months while working at my first computer-graphics-related job.
It features several fundamental real-time rendering techniques, most of them enabled, but some of them (SSAO, instancing) you have to dig a bit into the code to enable.
- Normal/parallax mapping
- Shadows (from directional and point lights, using shadow maps)
- Post-processing (tone mapping, bloom)
- Deferred shading
Disabled/work-in-progress features include:
- SSAO
- PBR lighting
- Normals in the G-buffer seem to have an incorrect orientation
I do not plan to clean up this project anytime soon, as it was mostly used for self-teaching at a time I did not know much about computer graphics. It is, however, quite a big project, with a fairly complex scene graph, some game programming patterns, OpenGL helpers, and even a homemade "Vulkan-like" (big quotes) render graph that computes the order of subpasses based on inputs and outputs. It should be fairly easy to build and run if you want to take a look, and you don't mind the mess :)
