Do you mind adding JSDoc for SubgroupFunctionNode?
For new modules, we should add documentation right from the beginning. Use FunctionNode as an orientation

For the class, how about this:
This class represents a set of built in WGSL shader functions that synchronously execute an operation across a subgroup, or 'wave', of compute or fragment shader invocations within a workgroup. Typically, these functions will synchronously execute an operation using data from all active invocations within the subgroup, then broadcast that result to all active invocations. In other graphics APIs, subgroup functions are also referred to as wave intrinsics (DirectX/HLSL) or warp intrinsics (CUDA).

It would be important if we had an example using this feature, just to be sure that this feature will be working release after release. |
Working on it 👍. Been busy with work. |
