Create a plate and move its vertices

Hello all!
I’m very new to both panda3d and 3D programming.
Can someone explain how to create a plate with a grid of vertices and how can I get back the vertices and move one by one?
For example, create a plate like:

|----|-----|
|    |     |
|----|-----|
|    |     |
|----|-----|

And than move the center point a bit to the right to become:

|----|-----|
|     \    |
|------|---|
|     /    |
|----|-----|

Can it be done easily?

Best regards,
Andy

Direct control of vertices at runtime isn’t frequently done, but it’s possible. The manual has a whole chapter that describes this process, under Advanced operations with Panda3D’s internal structures.
