How to dynamically update the geometry of a mesh?


Recommended Posts

I've created a BoxGeometry and assigned it to a Mesh, then when I click on the Mesh I would like to trigger an update of the geometry, for example change its "size" parameter. Is there a method I need to call on the Mesh to update it? I can see that the size property of the geometry gets updated, but the Mesh is still using the cached version.

This is probably an easy thing to do, but I'm struggling a bit as I'm very new to Babylon.

I've created a PG here: http://www.babylonjs-playground.com/#JTA9RH

Any help would be much appreciated :)

Hello everything is here:


Here is an example: https://www.babylonjs-playground.com/#1UZIZC#6


If you want to use pure shape functions, I recommend to directly use the MeshBuilder: http://www.babylonjs-playground.com/#JTA9RH#2


Ok so basically I need to reassign the "mesh" variable to a newly created mesh. Thought there was a method to explicitly trigger a mesh update, but that's fine too. Thx!

There is (the one I used in the playground I mentioned) but it forces you to build the geometry manually. If you just want to recreate a new geometry, then this is the best way :)
