Modifying 3d model using code

Question

I am building a piece of software that uses Kinect to measure a user. I want to roughly display these results on screen in the form of a 3d Model.

Essentially what I want to do is modify a 3d model using parameters (waist, height, chest, hips) to make it represent the user.

I am using XNA and ideally would like to make the modifications in xna

Any ideas how to go about this, or any pointers as to where to start researching would be greatly appreciated.

Answer 1

The technique you're after is often referred to as "rigging", where a 3D model is attached to a skeleton which can be manipulated to animate it.

If you have the time, I'd recommend downloading the very good open source 3D modelling tool blender. Once you've got your head round the idiosyncratic interface, there are many tutorials out there, plus info on how to export from blender in a format XNA can use.

Creating a good rigged model is tricky though - you might want to get an experienced 3D animator to help.
