Orthographic projection

What's it useful for?

Slowing your game down and messing up your Z-Buffer.

Ohhh you mean good stuff? Games without perspective. Completely flat top down in 3d, or isometric. Stuff like that.

Editors.

Ok thanks. Just wondering as it completely confused me, to be honest.

I use it to generate anim strips for 2d art from 3d models.

Create Lightmaps for terrains.

I use it for Editors as well.

I use it for headaches.

Orthographic projection - the fun community projection ;)

Orthographic projection is a feature from directx. Blitzbasic based on directx.

I mean... it isnt senseless..

(hmpf.. my english isnt good)

Orthographic really shines in it's use in editors for lining things up. Other than that, it's use is much less appealing.
