Storage Buffers Compute

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:

• /src/compute_worker.gd
• /src/compute_shader.glsl

Compatibility

Tested with:

• Godot 4.5
• Godot 4.4
• Vulkan API

Compute shaders are not supported in WebGL/Compatibility mode.
