How to use the Texture2DRD object to enhance compute shader visualizations and simulations in Godot!
This advanced tutorial covers the steps to take a basic compute shader and supercharge it using Texture2DRD.
Includes details on using it with the Godot main rendering device and the rendering thread.
This isn't the only use for Texture2DRD, but it fits great with the work we're doing on the channel.
Most of the simulation projects on GitHub have been updated with this technique - improving framerates by over 2x (in some cases). There is still a memory leak that I need to fix because I'm not clearing RIDs so watch for that.
