How to create shape from vertices in code side?

I wrote class which inherit from ShapeBase, and it is available from script side, so I can create objects of that class but shape is only creating when I specify shapeFile in dataBlock. Is it possibility to create shape hierarchy in ShapeBase basing class from list of vertices, put on it material, and change texture coordinates in C++, not in torque script? How to do that?

Thanks in advance
