Resample and optimize imported animation curves (similar to Unity's built-in FBX importer) #663

Open kodra-dev opened 11 months ago

Is your feature request related to a problem? Please describe. Unity's built-in FBX has options to resample imported animation curves, which reduces the amount of keyframes by a lot.

The sample animation as .fbx: Screenshot 2023-12-20 180554

And as .glb: Screenshot 2023-12-20 180545

See the huge difference in the number of keyframes.

Describe the solution you'd like Something similar to Unity's FBX importer settings: Screenshot 2023-12-20 180648

Describe alternatives you've considered Uh... using FBX instead...?

Thanks for the suggestion.

Although I see the value in this feature request, I don't think glTFast should put effort into fixing corrupt or sub-optimal input data (at least before other more essential features are implemented first).

The FBX feature cannot be easily re-used, as it stems from the FBX SDK itself.

I suggest to use other third party tooling to optimize the animation clips.
