TinyPBR - A small & simple PBR rasterizer

This is a small renderer that is able to load in a (single) chosen model and uses a PBR pipeline to present it.

There are a few scenes to pick from:

• Sphere | Simple Color: presents a sphere with some properties the user can edit like 'Color' or 'Metallic'
• Model | Simple Color: the user can select a model, then manipulate it's shading with some properties.
• Model | Load Texture(s): the user can select a model and all bound (PBR) textures to that model will be loaded in and used.
• Model | Select Texture(s): the user can select a model and then select textures per (PBR) texture type. Use this when you've textures that could be used on any sort of model (e.g. ground or rock textures ).

Why did I make this?

I made this project since I was learning about Physically Based Rendering for the first time. So I wanted a fresh environment with just a straightforward way of using it so I could test my PBR implementation and see if it worked. Afterwards once it was working I added some extra UI so I could play around with it more, basically making it a toy renderer. The project overall took around 10-20 hours of work. Mind that the code quality is quite low, this project wasn't made to be a robust or performant but to test out the things I learned/researched.
