During week 7 of KKB210: Computational Arts 1, we were introduced to Quartz Composer. Quartz Composer uses patches to create a composition framework of audio and video through different classes and protocols.
Our first exercise was to make a rotating cube and apply the provided Marilyn painting to each side in a different colour. This was reasonably easy as the colours could all be controlled just by changing the settings in the cube Patch Inspector.
As the final part of the week 4 KKB210: Computational Arts 1 tutorial, we were provided with a copy of the source code for a sketch/program/challenge that was originally written by Casey Reas. It is based on Pong, though it only partially works, as the challenge is to make it work completely.
We did not work on the challenge in class, instead we looked at bringing in a picture to use as the background and creating tints.
The final part of the KKB210: Computational Arts 1 week 4 tutorial was to import an image and make use of it. Processing supports .gif, .jpg, .tga and .png image formats.
Now that we have got the motion more controlled, we can go on to do other things with it such as add semi-transparent trails to the movement, change the speed of the colour changes and size changes, and plenty more. This is what the next part of the KKB210: Computational Arts 1 week 4 tutorial was focused on.
To start with we will be looking at having the changes to the variables being kept at the start of the next loop. IE, having the loop start with the box in the same position and the same colour as it was at the end of the previous loop.
The third part of the week 4 tutorial in KKB210: Computational Arts 1 continued the focus on motion from the second part. For this part we used many of the things we had already done in the previous parts, but modified slightly to create more controlled movement.
You can easily edit the previous sketch to do this, or you can write it up from scratch.
