Signed Distance Field generator for Unity with Burst support
/*
Based on the Anti-aliased Euclidean distance transform described by Stefan Gustavson and
Robin Strand. For further information, see https://contourtextures.wikidot.com/ and
https://web.archive.org/web/20220503051209/https://weber.itn.liu.se/~stegu/edtaa/
The algorithm is an adapted version of Stefan Gustavson's code, it inherits the copyright
statement below, which applies to this file only.
The rewrite with Unity Burst support makes the execution 40 times faster by default,
and 75 times faster if the passed in textures are both of type TextureFormat.RGBAFloat.

Last active August 11, 2023 08:15 — forked from ciro-unity/MainLightNode.cs
A custom node for Unity's ShaderGraph to capture lighting and use it into the shader. Works as of Dec 2018, but the APIs might change!
using UnityEngine;
using UnityEditor.ShaderGraph;
using System.Reflection;
// IMPORTANT:
// - tested with LWRP and Shader Graph 4.6.0-preview ONLY
// - likely to break in SG 5.x and beyond
// - for HDRP, add your own keyword to detect environment

/**
* PURPOSE:
*
* Polynomial Regression aims to fit a non-linear relationship to a set of
* points. It approximates this by solving a series of linear equations using
* a least-squares approach.
*
* We can model the expected value y as an nth degree polynomial, yielding
