Edge blending / masks
-
I am currently also playing around with soft-edge-blending possiblities to edge-blend two projectors with Isadora. Until now, my approch was using alpha-masks/ramps, which works so far, but it's not really handy and I am also afraid of getting a nasty brighter or darker center on the overlap as I cannot control the gamma curve this way.
Are there any news about the best practice on edge blending with Isadora?
I am developping the patch on a pc, but the final project will be running on a mac. So a solution which works for pc and mac would be the best. Unfortunately this also means I cannot test the Quartz-solutions, but If this is the best/only reasonable approach, I will be able to borrow a mac from somebody for the preparations.

Hello,
Read this old discussion... Will be great to edge-blending two projectors directly with Isadora ( and not have to tinker ). It seem to me not a creasy possibility for professional software at this day -
**I have moved this to a more relevant section @[bagarrett74](http://troikatronix.com/troikatronixforum/profile/4954/bagarrett74)**Hello again,
I wanted to upload the izzy file to see how I could do an edge blend with the SEB quartz composer. I didn't create the original izzy file so some of the effects are not IC or QC. The original dance performance only used 1 projector but for my performance I have other video in the show that will need to be projected with 2 projectors, edge blended. So I wanted to try and edge blend the live video to make it more interesting. I realize that I am only using a standard def signal so I would be stretching the image over the two projectors. How could I patch this so I can do an edge blend with this file?Thanks for everyone's help. I have my system up and running and I am excited to start using it. -
Also; try this... It's not complete but it will get you started. @bagarrett74 ;)2f2ef5-magneticfieldsedge-blend-1.izz

Thanks Skulpture. I appreciate you doing that. So with this file I should go through Blendy and Madmapper to do the edge blend. Also what do the fader actors do in this setup?
Thanks again. -
You had "Control Watcher" actor linked to each individual projectors intensity - presumably so you could fade each in/out each output? This does the same thing in essence.
There are a few options really. Edge blend seems to be the common method for the time being.You need to send this out via a syphon output. -
on a production in february i fell in love with Mapio - granted it was a bit of a pain to do back then since I had to do a work around to get mapio to work inside quartz (it was more a plugin than a stand alone application) so I was doing Isadora > Syphon > Quartz with Mapio output.
But mapio 2.0 lite is out and mapio 2 pro will be out soon... looks like you can just syphon right into mapio 2.0 and use that as the final output interface to do mapping/edge blending/cropping/warping in some kind of ready intuitive way. Anyways I will probably be going that route for the remount in the next few months.http://visution.com/mapio -
It can also be used as a FFGL plugin! @Mark, that's potentially very exciting for our future!
Cheers,
Hugh

Hello all,
SEB actor is not working for me, so I went hunting through the wide web.I've tested Millumin, Blendy, Mapio2lite.After that, I jumped on this thread: http://www.vidvox.net/forums/viewtopic.php?f=22&t=5863&p=21811&hilit=edge+blend#p21811I downloaded the edgeBlend-01.qtz which is intended to work with a TripleHeadToGo, and I modified it to blend for a Dual Head to Go.I will test it with 2 projectors tomorrow.Attached are the QC comp.Hope they can help.Regards Loïc369a34-edgeblend-01.qtz.zip 2ff725-dual-edgeblend-02.qtz.zip
