I have a question about exporting a 3d model that has been posed so that it retains that new popse for 3d printing. Right now we have a single animation clip that has all the different poses and we can go between all of them. It is my understanding that animations in three.js happens using shaders…

Is there a discrete number of static poses you need to export? Or does the animation blend between poses, and you need to be able to stop the animation at any point and still get the data (on the CPU) for that in-between state?

There are a discrete number of static poses and there isnt any blending. I use that custom PR you submitted for splitting a single animation into multiple clips. Each pose is a single frame and I stop the animation once in that pose. So I know it would be possible to get the data. But I’m not su…

If you can bake your poses into morph targets (or “shape keys” in Blender) then I think you should have a relatively easy time replacing the base geometry of the mesh on the CPU, using the morph targets. See: https://blenderartists.org/t/is-it-possible-to-bake-armature-poses-into-shape-keys-morph-ta…

We are currently baking the animations in blender. Are you saying that this should be sufficient or do I need to handle the animations differently ? Let me ask that a different way. Does this mean that instead of using animationclips/actions, I need to execute the animations by applying the morph …

It sounds like you’re going to have to apply either a skinned animation or a morph target to the base geometry. Since both are normally computed on the GPU, it will require some manual work to do so on the CPU and get the resulting data back out. Doing this with morph targets will be significantly e…

I have a couple questions before I go down this path. Will this mess with current skinning? i.e. if I use shape keys to pose the model, will that also move the armature and all other bound objects somehow? I’m thinking about how to get gloves to fit a hand correctly. Also, it seems like this migh…

Each shape key will be the same size as the base geometry, yeah. If your model’s size is primarily geometry, that could be an issue. On a closer look, it might not be as much work as I thought to implement skinning on the CPU. See this thread and this PR for some example code that can compute the (…

I’ve implemented the bounding box solution described here: https://jsfiddle.net/fnjkeg9x/1/ , but the problem I’m running in to has to do with async code. Because they are discrete changes in pose, I really just want to update the AABB once per pose change. If I call the function to update the AA…

If I call the function to update the AABB in the pose function, the async action.play() function doesnt complete prior to the call to the update function, so the updated AABB is always one pose change behind. Calling mixer.update( delta ) should apply your animation synchronously.
