Perhaps not boasting the most descriptive of names, BabyGL is an OpenGL learning experiment that renders geometries illuminated via adjustable point-lights.
Note that although the running demo only features spherical geometry, the other parametric surfaces within par_shapes are also supported.
It is worth mentioning that there is a single green directional light pointing upwards in this scene. Future work may expand on this, or simply have it removed.
A pre-built binary is available within the build folder.
./build/main.exe
To build a new binary on a Windows environment, first run the appropriate 64-bit
vcvarsall.bat, then ./build.bat.

This project was created as a way of learning opengl, and graphics programming in general. The amount of learned material is both varied and vast, and that list is best discovered via a peek over the project source. For the sake of brevity, a list of each shader with a notable highlight are included below.
| Shader | Notable Highlight |
|---|---|
| GPass | Writing geometry information to texture. |
| LPass | Passing information via uniform buffer object. |
| Bloom | Altering shader via subroutines. |
| GUI | Building geometry from information passed via vertex buffers. |
| Outline | Working with stencil buffers. |
| PerlinTexture | Precomputing a texture via shader for future use. |
