SharedArray Demo

A Unity project that visually demonstrates the use of the SharedArray library, to achieve more efficient integration with Unity's C# job system and newer math types.

Running

Clone this repo & open it as a project in Unity 2019.3+.

To run the demo, open the SharedArray Demo scene, inspect the Demo Mesh Drawer object in the scene, and click ▶.

What It Does

Arbitrary calculations for changing the position & color of mesh instances are performed, each frame.

These are done on worker threads, in C# jobs, using Unity.Mathematics types & the Burst compiler.

After the calculations are complete for a frame, we draw the updated mesh instances.

The same data / memory used in the calculation jobs is used as a normal array on the main thread, without copying.

This is so we can use that data as arguments to Unity methods like Graphics.DrawMeshInstanced that take normal C# arrays.
