I got as far as making the the geometrical objects and aligning them and also with help of some patches I found on this side I can use several projectors for one or more objects.
What I cannot figure out is how to get this tracing effect etc.
Hi I ll try to post something later on although it s an idea in a very early stage, anyway beware that there may be less painful ways to achieve it (writing a dedicated shader maybe?) and that 90% of the work is not the patch itself but the selection of the vertices over the time ie: a way to control it.
cheers
Here a starter idea, as mentioned before I guess there are far better ways to accomplish it, and I ll post some more stuff soon so we can try to work it out together, anyway have a look at it maybe you can come out with something better.
And one more, this is the most flexible one, although you ll have to create your own animation with timeliner or a MIDI sequencer, or parsing and XML file, whatever.
