Picking and Selection.

I am creating a 3D city. I am loading in 3ds models into the city’s for buildings. I want the models to turn Red when the user clicks on it with the left mouse button. I am unsure of how to work picking and selection so that each model I create is an object that can be clicked on.

I have found some code, but it will crash about a good portion of the time and point me the bit of code that determines if the object has been hit.

Any ideas?

This site has a good tutor on it.
