Drawing the human silhouette with bezier

Hello guys,

Sorry but I will try to ask something complicated again ... (laughs) ...

Below are two code snippets in the first example has a "silhouette" human, designed with bezier, the example I took in OpenProcessing.

Then there is another code, which like to do something similar, ie have the outline of the human body, but only in 3D, with proscene library could to facilitate rotacionamento, I got an example here in the forum.

Someone would know where I FIND tips on how to facilitate to mount coordinated the human body? (Build the mesh ...) to make these contours in 3D?

If anyone can help me with any tips, I thank the attention.

Thank you very much
