Overview

orthoscopic turns on and off the perspective handling. Turning on orthoscopic rendering removes the effects of perspective. To adjust perspective rendering see, the Field of View command.

Performance Notes

Turning on orthoscopic rendering improves the rendering speed by a factor of 2x-4x! So, if you have large images, or are rendering a movie that does not need perspective in the images, try turning off perspective by setting orthoscopic to 1.

Examples


Syntax

set orthoscopic, on
set orthoscopic, off
