UUUnmei / RenderLite

my first soft rasterizer

RenderLite

my first cpu rasterizer implement some basic technique

Features

• programmable pipeline, easy to switch shader
• right hand coordinate, like OpenGL
• perspective correct
• face culling
• cvv clip
• homogeneous clip
• orbit camera
• skybox support
• ASSIMP integrated，enable to load various model
• STB_IMAGE integrated, enable to load picture（texture）
• simple math class(vector, matrix)
• MSAA4x(deprecated)
• some extra 2d stuff in Draw2d
• wireframe or triangle topology

Limitations

• Windows only
• a few implementation may not easy to read
• performance relatively low(release build prefer), generally for only one model

Dependencies

• stb_image (included already)
• assimp 5.0.1 (NEED to config VS project settings; only use some basic functions, so maybe is ok to make a difference)
