I suggest you use morph target animation for this use case. In Blender they are called Shape Keys. You can then export to glTF
and import via THREE.GLTFLoader
. The twist can be controlled by modulating Mesh.morphTargetInfluences. It's even possible to animate a transition from on state of the mesh to another.
Note that loop cuts do not exist as an entity if you export a mesh from Blender to e.g. glTF
. It is of course possible to change the geometry in three.js
as you like but using morph targets seems the easier approach. Especially for a beginner in three.js
or computer graphics in general.
