// I modified Aras Pranckevičius's awesome shader code to be able to handle Infinite and Not A Number numbers
// Tested on Unity 2023.1.0a15 with ShaderGraph 15.0.1.


// Quick try at doing a "print value" node for Unity ShaderGraph.
//
// Use with CustomFunction node, with two inputs:
// - Vector1 Value, the value to display,
// - Vector2 UV, the UVs of area to display at.

// Native queue collection with fixed length. FILO.
// NativeStack<T> supports writing in IJobParallelFor, just use ParallelWriter and AsParallelWriter().
// Not tested to much, works for me with integers and unity 2019.3
//
// Assembled with help of:
// - NativeCounter example (https://docs.unity3d.com/Packages/com.unity.jobs@0.1/manual/custom_job_types.html)
// - How to Make Custom Native Collections (https://jacksondunstan.com/articles/4734)
// - source code of NativeQueue and NativeList

Vercidium

// Code ported from https://0fps.net/2012/06/30/meshing-in-a-minecraft-game/

// Note this implementation does not support different block types or block normals
// The original author describes how to do this here: https://0fps.net/2012/07/07/meshing-minecraft-part-2/



const int CHUNK_SIZE = 32;

// These variables store the location of the chunk in the world, e.g. (0,0,0), (32,0,0), (64,0,0)
