Fish eye lens effect.

Has anyone else noticed a 'Fish eye lens' effect with graphics rendered using Irrlicht? Take, for example, the image at http://irrlicht.sourceforge.net/images/shots/055.jpg. This shot clearly shows an unusual bending or warping of the graphics around the edges of the view. Any ideas why this happens with Irrlicht? I've used several other engines which don't have this effect. Is this a bug, or was Irrlicht designed that way?

Thanks!

This has been discussed several times before, e.g.

Please search the forums before posting.

Cheers.

On top of that, it's not a bug and all of those engines that you used before can do it if set "improperly" for the distances being rendered.

OGRE gets nasty if your nearplane and farplane are not within a certain ratio of each other.

By adjusting the FOV, Aspect Ratio, NearPlane and FarPlane, you can adjust the lens to get the perspective that you want.
