Hi All!

 ![MicrosoftTeams-image (9)](https://canada1.discourse-cdn.com/flex035/uploads/threejs/original/3X/1/b/1b96e905acde460c055bafc73ce822615a812e19.jpeg)

the demo:

this is a project where I use a earth elevation map to have the vertex points explode radially. Really like the point cloud version of earth, where I used this for help

> Thanks! This is the shader/solution I was looking for. However, I need the concept to also work on geometries like: const geometry = new THREE.TorusKnotGeometry( 10, 3, 100, 16 ); Anyone know how the shader can be adjusted? I will also try myself

thanks!
