You might find some suggestions in my addons. There shapes are also dynamically changed. I used self defined Geometry, indexed BufferGeometry and non-indexed BufferGeometry.

> For the first time, I came across three.js in January 2016. Since September I have been working on this issue. In three.js core elementary geometries are defined. When designing my “Bumblebee Mara” I needed other shapes and produced them by deformation of sphere and cylinder.

> updated NOTE: Modular bundling of multiple geometry definitions has some advantages, but also disadvantages if the overview and maintainability suffers. Therefore I created newer geometry creations in extra files and collect them on Github at [GitHub - hofk/threejsResources: Resources for three.js](https://github.com/hofk/threejsResources) There are also extra posts about it here in the forum. The THREEg addon is used to create special / extended geometries. [20180208-2112-21658] The addon generates non indexed BufferGeometries. Th…

Try it out 🙂
