Multi Projection (like Module8)
hello
I would like to programm a multi projection patch for jitter.
You can see what i mean in module 8:

In attached file, you can see my aim. I would like to define the red rectangle which is the workspace for video stuff, like position, rotation…
As you can see, when the videoprojector is not in the axe, there is a "matrix overlap". So I need to be able to define the position and form of every videoprojector's matrix.
Do you have any ideas, tricks or tips to do that ?
Maybe something between the render and the window ?
Thank for your help!

great idea, (and drawings too)
are you planning to integrate some funky parameters for perspective correction?
did you have a look at hc gilje’s VPT patches?

search the Jitter forum for "edge blend" or something similar.
andrew benson posted a great example patch a while back, but i think it got lost in the forum shuffle.
here is what i have from him on my computer. i’ve never actually used this, but it should get you started.
Here’s the link to the thread where Andrew posted his shader-based solution. It also includes a link to my "clumsy but working" 2-screen solution called "Edge Blender" with adjustable fade contour. You could hack that to add other transformations…
Thank you all for answers…
i’m back for this project!
I’ve take a look to the display3proj attached by Robtherich (thx!)
It seem to be good to do what i have to do.
BUT.
Of course, i’ve some trouble with adaptation…
The patcher only allow an Y’s corner pin correction. But in the case expose in my first post, i’m needing an X correction too.
I’ve tried to merge it with an old patch with corner pin (X and Y) correction, but it doesnt work.
Do you think it is possible ? Any tips ?
Thank you again!
i would post what you have with detailed comments about what is supposed to happen and what is not happening as expected.
