Shape Animation Examples using SDF. Shaders are written in MSL (Metal Shader Language) with SwiftUI.

## What's this?

本リポジトリは、書籍「[リアルタイムグラフィックスの数学 - GLSLではじめるシェーダプログラミング | 巴山 竜来](https://amzn.to/43tnJy7)」の [GLSLサンプル](https://github.com/yutannihilation/math_of_realtime_graphics_wgsl_version) を MSL (Metal Shader Language) で写経したものです。

主に第II部「距離が作りし世界」のSDF関連のサンプルを扱っています。

学習のため、最小限の構成にしたサンプルや、3Dだったものを2Dにしたサンプルを追加したりもしています。
