Particles across different stages

spoynton

Hi, I am looking at producing an installation using isadora, one Mac Laptop and three projectors. I'd like to generate a particle field where the particles move across different stages. Is there a way to do this?I'm having trouble as the 3D particle actor has a Stage Target attribute and when projecting from different projectors each is given a different stage. Any thoughts?

Thanks

You need Matrox TripleHead2Go for your projectors(there is plenty of explanations how this device works). Then in Isadora you use scene that is 3 times wide(that will be split onto each projector) where you move the particles around.

I added a patch to show you how it is done. You have to set the destination of "3d particles" actor to renderer, then the image is sent to the "3d renderer".

@Michel: Thanks! This answered a slightly different question for me.

Seems like a gpu crop actor might be a very valuable edition.

@DusX

You can get the same result with the mapper, but not so quick.

It would be very helpfull to have control marks/lines in the mapper to know where is 1/3 or 1/4 of the image.
