Hi,

I must create a software which will display a tooth in 3D, this tooth should transparent.

There should be an object that slides inside and
outside it and this object's edge apperance should be changable.

The tooth must be rotatable in Z axis.

I am a total noob to graphics, and don't sure whrere to begin.

I think that I should use some kind of game engine because it should be part of an application... I checked Blender, because it's free and it is a game engine, but don't sure if it suits my needs.

I don't need a fancy graphics and I'm looking for as simplest solution as possible.

It should be a little similar to this demo:

I'm a total nube to 3D graphics so I will be happy to get as much information as possible...

Thanks in advance.
