QC Stereoscopic Recorder is my first Cocoa app! It is part of my work towards an MA in Computer Arts. The app is a component of a larger project called “Anamorphica” in a class called “Experimental Digital Media”. Further documentation of this project will appear over the next few weeks. Basically, I am aiming to make a low-cost open source anaglyph recording and ‘performance’ system.

To use it you will need two firewire cameras.

Performance is improved if each camera comes in on a separate firewire bus. To effect this, I use a Lacie firewire PCMCIA card in my G4 laptop.

I needed a simple application that would capture dual camera input, export to quicktime and make an anaglyph.

I have included “stereo-pair” generation. Stereo-pair generation will come into it’s own when the application can handle full-screen and dual monitor support. Then I may create a ‘Wheatstone’ device (see http://www.stereoscopy.com/library/wheatstone-paper1838.html).

QCStereoscopic Recorder would not have happened if it wasn’t for the wonderful “Quartz Composer”. Easy and a joy to use. As I am learning Cocoa and Objective-C, the project is indebted to sample code and open source initiatives.

• demo code from Apple - QCTV / Pierre-Olivier Latour
• the wonderful “Sparkle” by Andy Matuschak (www.andymatuschak.org) handles software updates from within the applications.

To Do

• full screen mode
• improve image contrast quality
• fully implement Apple help
• export print resolution single frames
• implement VJing style performance control

Notes

• Built as a universal binary - untested on Intel
• tested on PPC - 10.4.4

Have fun!
