## Realtime CPU Software Rasterizer

![rasterizer](https://github.com/maxbrundev/Rasterizer/assets/32653095/0c8099a7-6bdf-48cd-a0fb-d07e6d025843)

## 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`)
