Unity 2020.1+ Texture Access API examples

Unity 2020.1 added Texture2D.GetPixelData and related APIs for C# Jobs/Burst compatible way of reading & writing texture pixels (see documentation).

This repository contains a small example of that. Required Unity version is 2020.1 or later.

Procedural Plasma Texture

An example where a "plasma effect" texture is updated on the CPU every frame.

Assets/PlasmaSampleScene is the sample scene and code.

Time it takes to compute plasma and update a 512x512 texture, on 2019 MacBookPro (Core i9 2.4GHz, 8 cores / 16 threads):

SetPixels: 113ms,
SetPixel: 140ms,
SetPixelData w/ Burst: 17ms,
SetPixelData w/ Burst, parallel jobs: 1.7ms.
