Vue Stereo Image Camera Creation Script

impworks — Sat, 15 Aug 2009 23:02:35 +0000

This python script creates a pair of cameras for rendering stereo images in Vue. It’s pretty easy to do without the script but this just speeds things up a bit. Christina has two tutorials about making stereo camera’s on her web site. Its a basic solution that doesn’t generate an animated camera and it won’t work with cameras that aren’t flat and level. Originally created after a request from Jim Coe.

Note: This script does not render the scene. Once you have used it you will need to render the scene from each camera yourself and do whatever magic you need to do with the output.

So glad I switched this site to WordPress – adding new pages is so much easier.

Tonight I’ve added a new page for the simple Vue Stereo Image Camera Creation Script I wrote back in 2007.

I was asked by Jim Coe if I knew of a script for creating a pair of cameras for rendering stereo images in Vue. I didn’t but writing one wasn’t particularly difficult. It isn’t a complete solution as it won’t generate an animated camera and it won’t work with cameras that aren’t flat and level. So here is a quick Vue python script to do just that…

Edit: Of course you don’t need a script to create stereo images using Vue. Christina has two tutorials about this on her web site.
