Example for animation?

[jimver04]

Hi,
The provided samples are very limited .
is there a serialization example for exporting animated meshes in glb? Rough directions?
Thanks,
Dimitrios

Maybe try looking here: https://github.com/BabylonJS/BabylonPolymorph/tree/master/Morphs/Importers/Transcoders/Transcoders/Source

Hi,

the BabylonPolymorph was really a help.
I have achieved animation for the morph targets by replacing the VerticesArray per each step:

accessorIdPositionsTargets[stepidx] = bufferBuilder.AddAccessor(VerticesArray, accessorDescMorphingCoordinates).id;
meshPrimitive.targets[stepidx].positionsAccessorId = accessorIdPositionsTargets[stepidx];

Can I animate also Vertex colors ? From I what I see I can not put them in the TargetPath of the morph.

Best,
Dimitrios

Not with the core spec. There is this extension that animates other properties, but I still don't think you can animate vertex colors. That will be difficult to implement since vertex attributes will have to be updated every frame.

I agree - the examples need a ton of work. The Serialize/Deserialize should really fan through almost all parts of all the different type in a normal parsing way. They're too limited.
