Exponential Controls

Quick tip:
Use the Interpolation Patch to give your controls different curves.

The key is to right-click the Patch, and set the Timebase to ‘External’.
Then, use a Splitter with a range of 0.0 to 1.0 connected to the Patch Time in port. You can then set the Start and End values to anything you like to scale the output. You can even set the Start value to a number greater than the End value, to reverse the action of the slider.
You’ll need to set the Duration to 2 also, or you’ll find that you’re not able to use the complete range of the control.

Cylinder Iterator

New qcFX. Another variation on the Iterator theme, this time using QC 3s new Cylinder primitive.

Up to 50 cylinder objects are nested inside each other, with the input image mapped onto their surfaces. Controls allow rotation of the elements, and incremental offsetting and rotation of each cylinder. I’ve also made use of the option to set the top and bottom width of the cylinders seperately, so you can create cone shapes too.

No coding in this one at all, just lots of nested macros!

Meta-Image

Recreation of the classic ‘Meta-Image’ effect, where the image is recreated from tiny copies of itself. This basic version took me about an hour to create, as it’s essentially just a variation on the pixellation effects I’ve done before.

tb metaImage 1.0

The plan is to add the ability to zoom each tile (maybe with the option also to set the centre-point of the zoom), and maybe centre each row and column so the effect appears to scale from the centre, rather than the bottom-left of the image when the Cell Size parameter is tweaked. Not quite sure how to do that yet though.Oddly, I’ve had to flip the image tiles vertically, otherwise they come out upside-down in VDMX (but the right way-up in Quartz Composer, bizarrely).

This is a Tiger version, but it should also work in Leopard.
