This is called "culling," and I've understood that the GDK does it automatically in its rendering pipeline. But I can't be certain.

I think what you need to do is to look into LOD steps. LOD is for Level of Detail. There was a newsletter article about doing this quite easily, a year ago or so, written by Lee Bamber. I think it should introduce you in the right way.

Essentially what it means is that you only show the pretty tree when it's close to the camera and then exchange the detailed model for models with fewer details or even a sprite when it's farther from the camera.

culling and lod are both supported by gdk

culling works automatically, you have to write no code.

lod has an easy setup
