If you are on OSX you can also try AR toolkit, there is a version for quartz. You have to mark your target with a fiducial (can be done with IR reflective material (you can train your own fiducials). The advantage of this is that is gives a homography matrix back that allows you to easily get a 3D rotation of the target on which to re-project. I have used this a few times and it works well.

this will be very helpful, thank you.

haha - Yeah its a bit of a beast :-)

I've done similar projects and its really just a matter of combining a Limit Scale Value for the ratio and a calculator for the offset for each dimension that's being manipulated and then tweaking the math until it works properly.

thanks fred, works great!

hello Peter

came across this testing the new syphon stuff in IsadoraCore, ok make sure you see the air-stream on your mac screen,(mirrored iPad), now use the syphon actors in Isadora, made some syphon list patch reads all available syphon servers (QuartzComposer)

Wow, Skulpture thanks so much that made it so easy. I just took a class with Mark in NYC and he said that they were working on the tutorial. My issue was with the OSC routing piece. Thanks for sending the link, it works very well now. I added the smoother actor to help with some of the shakiness and it works great!

Thanks stj!

i found a solution using evelope generator und videoFader.

See attachment... (trigger the envelopegenerators for showing the text)

Basically you freeze a picture, fade to the frozen picture, change the original picture player to a new picture, and fade back to the original picture player. Again, though, I can assure you with absolute certainty that there is no application for which it wouldn't be a better solution to use two seperate picture player actors.

Glad I could help!

Hello,

this is from a patch I was working on a few weeks ago; it's fairly similar to the one posted by Michel above. We were trying to recreate the effect of a long exposure picture taken with a stills camera but the principle is similar. Swap out the 'Video In Watcher' for a combo of the 'Stage Mouse Watcher' & 'Shapes' as in Michel's patch. It will give slightly different results to the motion blur patch, try playing with the frequency of the pulse generator to get different effects. Best, Crofty

Sound Flower is the way to go. Make Sound Flower your main sound output -- that will get the QT movies to send their sound to Sound Flower.

Then use the Core Audio "Sound Input" actor, and set the 'device' input to Sound Flower. Add your sound processing actors, and finally use the "Audio Device Output" to send the audio to whatever output device you'd like to use. Best Wishes, Mark

Merci à Pascal et Armando pour leur prompt réponse à mon interrogation.

Comme il y a des (Actors) que je ne maitrise pas, je vais faire quelques essais pour mieux comprendre le processus. Je vous tiens au courant. Encore merci

Ah, ok so you are working with the 'SYST3M ultraDMXpro' actor.
My guess is that some init setting is stopping it from running (did you browse the internals? if so did you save update the actor when you left? some minor change might have been saved into it.)
.. really hard for me to say, I haven't looked at it for sometime since I have it running very well for a few projects
.. I know I have tuned it a bit in a recent project, and should probably do an update to my site.
My suggestions would be to add the original one (as it was downloaded) to your global actors folder.. this way you have access to a clean starting point that has proven to work for you.

In anycase I am glad its working for you. Do let me know if you have any other issues with it.

A free downloadable tutorial showing the very basics of video mapping onto a cube. Hopefully this will help some new members get to grips with the basic concepts.

@armando i like your solution.

i'm going to consider if i can metaphorically build the bridge between what i perceive as the potential of the kinect to actually achieving it. to do this i first need to get beyond the frustrations that develop when attempting to work with the kinect.

please search this and old forum for tracking; there are many - even for background subtraction.
