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

If I understood correctly you are updating vertices here:

else{
        theObjects[i].mesh.geometry.vertices = theObjects[i].geo.vertices;  
}

Try to change this code to :

else{
         theObjects[i].mesh.geometry.dynamic = true;
         theObjects[i].mesh.geometry.vertices = theObjects[i].geo.vertices;  
         theObjects[i].mesh.geometry.verticesNeedUpdate = true;
    }

In if(){} you create a mesh and in else{} you update so dynamic = true and verticesNeedUpdate = true you need to set to mesh which is in else{}.
