core imageFace Off (Quartz Builder Interaction patch App Test) (Composition by gtoledo3)
This is a simple test app. The basic idea is this: -Make 4 points on the viewer by clicking with a trackpad (haven't tested with mouse), in a clockwise or counterclockwise manner. -"Grab" the area in between the 4 points (this is where the new SL interaction patch is implemented). -Move it out of the way to reveal a backing scene. -Put two fingers to trackpad and click to clear points and reset. The one caveat in operation of this is that the next time you select four points after your initial run, the x/y offset of the Interaction patch "window cutout" will be the same as the last run. This being the case, the idea is to return the "piece" back to cutout window before clearing points. The cutout area will track to motion, more or less. This is a 10.6 app, and will not work in Leopard, 10.5. Motion Tracking CI Dissolve (App) (Composition by gtoledo3)
This is a test application that allows one to set 4 (or more) points, using trackpad or mouse, that define an "intelligent", motion tracking, dissolve region, 2 finger (or secondary) click for a reset of the points. The concept is that one can have a video feed, or picture, and intelligently select regions that one wants to have effected by various CI filters. This is a basic implementation. Let me know if anyone runs into any trouble with it - It should work fine in Leopard or Snow Leopard. |
