The latest 3DRad (based on the 3Impact engine) has a new function called "Imposters" which allows many objects on screen without crashing.One user has posted a screenshot of 10,000 buggys on screen although he can only get 2fps not surprisingly,but imagine being able to have dense forests and the like.

Not sure if these objects are "real" 3d or really just billboard imposters.

nvidia has a nice instancing example.

billboard imposters are used first in the video game far cry (I guess).

That means you draw a complex object to a texture and use this cached texture to draw the object in the world.

So only need to update the imposter infrequently rather than drawing it every frame.


But yeah a cool feature for lots of trees, grass, stones and so on :)

They're real, you can do skinned meshes as well. FPSC X10 has this, too.


Pretty impressive product 3drad, and it's being improved very quickly as well.

mmh, I haven't tested 3drad so can't test it but my understanding from imposters are still this -> LINK (http://www.ericrisser.com/TrueImposters.html)

That's interesting. I'm not sure what method 3drad is using but this could be it. I was under the impression that they were instanced meshes, however this may only be possible in dx10.:confused:

Hm, that's the problem. It is impressive and promising as long as i know it. But nobody comes with a result. Has somebody finally made at least a small game with it?

They are not real, try to imagine the memory management of the situation....

10,000 or so objects with a relatively high polycount would eat so much memory you would have insane framerate issues if you did not freeze or crash.

If I am proven wrong I will surely admit it, not that I am not impressed, but I am uber skeptical.
