javascript中的A-Frame顶点动画

Question

Is there anything like a formula-deformer animation for A-Frame? The Idea is that I have a geometry in A-Frame and a js-script which makes the geometry wobbble. I tried the noise-shader from the A-Frame-Extras but it breaks the vertexes and doesn t look good and I m not a good coder to do it myself!

I`m happy about any ideas! Cheers, Can

Here is a simpler example that might help https://glitch.com/edit/#!/equinox-rainstorm?path=shaders/grass-vertex.glsl:9:5

Basically using a vertex shader to bend the top half of the mesh.
