Updating a Mesh

[JohnK]

Just started to use babylon.js and am enjoying its potential.
 
I have successfully created a curved by adjoining a sequence of points as in

curve = BABYLON.Mesh.CreateLines("curve", path, scene, true);

and adjusted points on the path and updated the curve using

curve = BABYLON.Mesh.CreateLines(null, path, null, null, curve);

However when I add new points to the path updating the curve using the above code does not give the correct new curve.

 

Using

curve = BABYLON.Mesh.CreateLines("curve", path, scene, true);

once again draws the correct new curve but leaves behind the original curve.

 

Is there a method of adding points to a path and to update the curve?

 

How do you delete an existing mesh in a scene?

Hello and welcome!

 

You cannot add nor remove elements this way. You have to create a brand new curve (meaning without referencing the previous one with the latest parameter)

 

Under the hood, this is because we can easily update the underlying vertex buffer but we need to create a new one if we have to change its size

Maybe is it missing in the doc the fact that only the point positions can be updated, not the point number.

 

dispose() will delete the mesh
