3 years ago Yeah I did, but actually not yet with sokol-gfx.
TBH I would actually use ozz-animation these days, but if you want to do it yourself you can have a look at my Oryol-samples. However the character animation-system and renderer is a bit more complex then usual because it renders characters optionally via instancing and pulls the bone animation data from a texture. It doesn't use GLTF as file format though, but a custom binary format.
Here are the relevant demos:

- https://floooh.github.io/oryol-samples/wasm/Dragons.html
The skinning shader is here:
The toplevel C++ code:
...and the important part is this character-animation module (this is the main part that would be replaced by ozz-animation):
...oh, and this Dungeon-Crawler demo also seems to have skinned characters:
...maybe worth looking at the source code:

Hello!
First of all - I just love the sokol headers! I'm tinkering with a small game runtime combining sokol with the equally excellent QuickJS javascript engine and it works like a charm!
Now I'm trying to figure out how to support skinned mesh animation with sokol_gfx. The gltf sample is a great start, and I'm guessing I could add the vertex skinning part of the Khronos gltf viewer reference pretty easily but I'm struggling a bit with finding the best approach to do the actual bone animation. Using something like the ozz-animation library could work but seems a bit overkill?
Surely @floooh or someone have messed with skinned animations in the past? 😀
