Over the past couple of day’s I have been playing around with Xcode and Quartz Composer, both of which are very powerful developer tools for the Mac and iOS platforms. This very simple ScreenSaver is the product of about 20mins work playing with Quartz Composer.
The scene shown by my webcam wasn’t very interesting but it gives you the idea of its capability, when loaded as a full screensaver, it also shows the time in various locations. Any feedback is welcome, I’m still just playing with the software, and any thing you would like to see improved or changed, drop me a comment and I’ll see what I can do.
Installation and System Requirements
Installation is very simple process, consisting of copying the 3D Webcam.qtz file from the zip to “MAC-HARD-DRIVE/System/Library/Screen Savers”. Once the file has copied, go to the ScreenSavers menu in System Preferences, and choose “3D Webcam” and Enjoy.
This ScreenSaver has only been tested on a MacBook Pro running 10.6.6, however it should run on any Mac running 10.5.1+. Please note, running this ScreenSaver on battery power, will drain the batteries quite fast (approx. 1hour continuos)
Version 2 is up – This version is only a minor update with a couple of improvements:
- The cube is now slightly smaller
- The cube now rotates slightly slower
- The cube now also moves around the screen, preventing black screen burn.
Today we looked at timecode with a substitute lecturer, the lecture today wasn’t very successful as they were trying to teach us directly from Martin’s note without reading over them before. We have been told to expect thatMartin’s absence will be for sometime, this could affect more of our BT lectures as well as our TV Systems and Signals Lectures, as he is our main course leader.
Today’s lecture was quite mismatched as he was just reading from the notes, and explaining the bits we did not understand, this still didn’t give us the full reason / story behind timecode and why we use it. I feel they could have gone into more depth on how it works technically and why its so crucial.
