Editing a vertex data in an egg model

[D_A_M_H]

Hello all.....

As I was surfing the manual I found a procedure to read the vertex data and primitive data of a model loaded

I found also a procedure for editing data of the vetices of the model using modifyVertexData() for making this but I couldn't find a completed code for this

Can someone give me a simple code on how to use this?

Thanks in advance
