Showcase of getting data into and out of GLSL compute shaders using Push Constants, Specialization Constants and Storage Buffers in Godot.
See https://1hue.dev/storage-buffers-compute-shaders-godot for further reading.
Example use of Specialization Constants — which are more efficient than Push Constants for input data that need not change during runtime — is included.
UI that demonstrates the concepts:
Scripts of interest:
Tested with:
- Godot 4.5
- Godot 4.4
- Vulkan API
Compute shaders are not supported in WebGL/Compatibility mode.
