Baking Animation

[manthrax]

I thought skinned animation vertex transformation happens on the GPU… how are you reading the transformed vertices out in bakeAnimation? I might be off base with this… but recall seeing code in threejs to do the vertex transformation in JS as well… I think i saw someone do something with that for computing accurate bounding boxes…

Box around a skinned mesh

Following this trope I’ve managed to get a bounding box of a skinned mesh: // simplified with boneTransform var aabb = new THREE.Box3(); var skinned = new THREE.Vector3(); var geometry = skinnedMesh.geometry; var position = geometry.attributes.position; aabb.makeEmpty(); for (let i = 0; i < position.count; i ++ ) { skinnedMesh.boneTransform(i, skinned) aabb.expandByPoint( skinned ); } aabb.applyMatrix4( skinnedMesh.matrixWorld ); (Seems to be working - fiddle). I’m having trouble In a situ…
