panda3d EggNurbsSurface

the EggNurbsSurface apiref says:

how can i call push_back from python, or what would be the equivalent function call? i get the feeling that’s not exposed. addVertex doesnt seem to be right, because i get a assertionerror when i try to convert the egg into a nodePath.

is there any sample around howto use EggNurbsSurface?

Ah, that’s a very stale comment. The correct method name now is addVertex(). If you’re getting an assertion error, it’s likely that you’ve added the wrong number of vertices. What is the precise error you’re getting?
