Title :
Basic Multiple Orthographic Camera Views
Author :
_PJ_
Posted :
1+ years ago
Description :
Gives a working, orthographic projection of a scene in wireframe with separate camera viewports fro Top View, Side View and Front View, but also adding a rendered, elevated camera view.
The code is quite static as is, but should be easy to incorporate the principle to any given scenario.
