Realtime CPU Software Rasterizer

Description

Basic and Advanced Rendering learning project.

Features

• Triangle Rasterization
• Line Rasterization
• Texture Mapping
• Clipping (WIP need cleaning)
• Mipmapping (WIP need cleaning)
• MSAA (WIP need cleaning)
• Vertex pass
• Fragment pass
• Depth Writting
• Depth Testing
• OBJ Parsing

To implement

• Improve architecture to mimic OpenGL API
• Profiling tools ...

⚠️ Optimization pass, architecture update and global project improvement is planned as soon as Mipmaps / Clipping / MSAA will be cleaned.

Software

• Visual Studio 2022

Dependencies

• SDL2 (Windowing and inputs)
• Assimp (3D model loader)
• GLM (Mathematics)
• stb_image (Image Loader)

Compiling sources

Premake5 is used to generate project files. To generate the project, execute GenerateProject.bat. By default, GenerateProject.bat will generate project files for Visual Studio 2022. If you want to use another version of Visual Studio you can execute GenerateProject.bat from the command line with the Visual Studio version as argument. (ex: .\GeneratedProject.bat vs2019)

Licence

This project is licenced under an MIT Licence.
