Is there is a way to clean the canvas or the sean?

[zied sellami]

Hi everyone
I'm trying to change the same meshes values to a new one.
The problem that the old instance is still rendered in the scene over the new one.
Is there is a way to clean the canvas or the sean or to clean the old meshes state ?

Might be me @zied sellami but I do not understand what mesh values you want to change or why? If you could produce a playground example and explain what you want to happen then maybe I could help.

 @JohnK ,  @NasimiAsl I'm trying to generate forms  so for that i manipulate all the Matrix (positions,normal,indice) i used my_mesh.dispose; my_mesh=null ; but after a few time using the application it comes slow , so i need a method that it init my sean to a blank step without load memory for the meshes that are disposed.

@JohnK I'm sorry but i cannot put it in the playground or show any exemple because it is confidential. i wish that you understand that

This topic has come up before

Sounds like a garbage collection issue. Do you still have references to you mesh? If so mesh will not be garbage collected.

This might be worth a read http://stackoverflow.com/questions/742623/deleting-objects-in-javascript

Are there other ways of approaching what you need? Could you update positions, normals etc in existing mesh rather than create a new one?
