Find attached screen_ortho.inc, which extents the abilities of screen.inc in
order to use the orthographic camera. This is related to the thread


http://news.povray.org/povray.binaries.scene-files/thread/%3C4afccd8a%241%40news.povray.org%3E/?mtop=406850

started by SharkD, who is the one that wrote almost the entire code. The
attached version includes minor bug fixes and improved documentation.

Use
    Set_Camera(Location, LookAt, Angle, Ortho)
to define your camera instead of the traditional `camera { ... }`. The `Ortho`
parameter accepts `On` or `Off` and gives the expected results. Use e.g.
`Screen_Object` to add logos, watermarks, subtitles or any other object which is
meant to stay fixed in front of the camera. (Validated to work with animations.)

Best,
Carlo

Now, make a version that will also work with cylindrical (all 4 
varieties), spherical, fisheye, omnimax, panoramic, and ultrawhide_angle 
cameras...

Hi guys!

Note that the latest version of my screen.inc is located at my web page.

     http://isometricland.net/povray/povray.php

The main alteration IIRC is that

     Set_Camera(<+25,+15,-33,>, <+2,+2,+0,>, 060, on)

was changed to

     Set_Camera(<+25,+15,-33,>, <+2,+2,+0,>, 060)
     Set_Camera_Orthographic(on)

This was in order to make the script backwards compatible with the 
original screen.inc that is bundled with POV-Ray.
