Creating a Modelling tools with jPCT-AE

[mazataza]

I have a plan to create an android APP which allow modelling of Building (a simple tools for architicture).
my question is how to modify all vertics in an Object3D after build it?
my tool will definitiv need a mesh subdivision which work on modifiy/adding vertics.
using IVertexController allow me only to change already exists vertics, but adding.

an example of modeling.
the user create a line , the user then add a point to to line and move this point, which mean the line will be splited to two lines which are joints with this new point.

Adding vertices usually requires to create a new object. In some special cases, you could get away with creating an object with lots of unused vertices (i.e. their coordinates are so way off, that they won't be rendered) and moving them into way at runtime, but that's limited and hacky.
