Updating a geometry inside a mesh does nothing

Question

I am using THREE.JS rev 49.

My program needs to update a mesh by changing it\'s geometry. Unfortunately the display does not seem to update.

Here is my code

Answer 1

When changing the entire geometry, I think the easiest way is to remove the old one (scene.remove(geometry), then add the new one (scene.add(geometry)). I think the cost of modifying the mesh and geometry parameters and properties is the same as adding a new one, although adding is much easier and saves a lot of headache!
