Voxel Raycaster (Voxlap-style) with baked cubic PBS/PBR lighting C#
- A voxel raycaster with baked cubic Physically Based Shading (PBS) and stylized outlines was created from scratch in C# with OpenTK.
- The renderer aims to capture the look of games like Jet Set Radio, Wind Waker, and PS1/PS2-era classics.
- Key goals include a stylized look, voxel-based 3D rendering, prebaked lighting to simulate advanced shading, post-processing outlines for style, portability, optimization, and compactness.
- The voxel texture is generated using procedural shapes like islands and crystals and employs multiple Global Illumination (GI) passes.
- Raycasting occurs inside a 3D texture with voxel color and alpha data using a fragment shader.
- An outline shader adds thick outlines around color or brightness changes, creating a cel-shaded, 'inked' look.
- Technologies used include C#, .NET 6, OpenTK (OpenGL bindings for C#), GLSL shaders (330 core), with no engine or Unity, just raw code.
- The project aims to be small, fast, customizable, stylized with an early-2000s console look, and fun to code and draw with.
- Future plans involve optimizing GPU performance, data compaction, and rendering tricks.
- This kind of project is ideal for those interested in rendering, graphics, or building stylized engines from scratch, requiring math, code, and creativity.
