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.

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