How to make viewport in 2d?

Need make wiewport in 2d. Like Unreal Map Ed.



Standart viewport make visible deep of model.(Example:Back side of cube visually smaller on perimetr then forvard)

Or need another graphic engine7 But mogre is powerfull.

The '2D' viewports use something called orthographic (or orthogonal) projection.
You can change the projection type of a camera with:
camera.ProjectionType = ProjectionType.PT_ORTHOGRAPHIC;

The wiki has an article that might be helpful (but it's for Ogre and might be outdated):
