Computational Arts by Matthew Brown

The second exercise of the week 7 KKB210: Computational Arts 1 tutorial was to have a look at a couple of files, cube-marilyn.qtz and 5-marilyn.qtz and effectively combine the two. The first file, cube-marilyn.qtz has a rotating cube, with a single Marilyn image on each side similar to what we had to make in the first exercise, except that it has two extra interpolations, so it now has one for each axis that it can rotate on. It also has a different duration on each axis, so it creates the appearance of changing speed. The second file, 5-marilyn.qtz contains a grid of four Marilyn images. They are all the same original image, but each of the four runs variations of exposure adjustments, gamma adjustments, alpha masks, colour inverts and other effects.

Now, the actual exercise is to take the image variations from the grid of the second file and apply them to each side of the rotating cube in the first. So each side of it will have the same four images with all of the effects and so on applied to them.

For me, rather than playing around with it, the best way to do this was to look at how each of the images had been done on the second file and then apply the same things to the images on the cube. It could easily enough be done using different effects on each side as well as each image, by duplicating the “Render in Image” patch a few times and applying each one to a different side (rather than the same one to each side), and then editing the image effects for each one individually.

The full size screenshots of the macro patches are available by clicking the above thumbnails. The .qtz file is available here, and the Quicktime movie is available here. There is one thing not shown in the above screenshots. When you double click the Render in Image patch, it takes you to four Macro Patches. These patches are the ones that contain the information in the second screenshot above. Each one of them applies to a different image in the grid.
