I try to build a reactable and , i really need some help for the visual feedback . Does somebody has a patch to show me ? Or some ideas …? Which nodes I’ve to use ?
I need some help to know how to create the “link” (the frequency signal) between two points…
If someone could help me , it could be great !
In order to deal with visual feedback you have to reinject the output of a renderer into the renderer input. Basiclly this is done in combination with the Group (EX9) (check it’s helpfile to look at the input drawing order)and DX9Texture (EX9.Texture) nodes.
@tonfilm made a patch demonstrating motion blur using visual feedback you can have a look here.
Is that what you are looking for ??

Thank you for the reply but , i think it’s not what i’m looking for .
But, you may could help me .
You can see a video of the reactable on dailymotion at : http://www.dailymotion.com/relevance/search/reactable/video/x2cxg6_reactable_creation
The “sound part” of the reactable is designed with Pure Data but, i’m prety sure that the graphical designed is made with 4V .
I think it’s not really hard to do this for someone who know 4V.
For the moment, I use the fiducialtraker node to know the coordinates of the fiducials .
But i don’t know how to represent the “sound signal” between two points like in the video…
What i call the “visual feedback” is all the graphical part of the reactable . The frequency , but also the round around the fiducial , the volume controller …
Someone tells me to use the “Roundrect node with the Rope node and some Transform 2D” but i’m a little bit lost …
I made my LinearInterpolotion thingy just for this purpose, now you have some points between 2 feducials, you can manipulate those points with the Scopespread, add some Circulairspread (factor 0.5, to make begin and end stick) and use my Points2Rope module and a Rope node. (for example).
I made this one with all things what you say here, actually it can handle the fiducials 0 and 1, just connect your camera and put in front of it these fiducials and put some music…
i dont know how produce sound, since the WavePlayer node is broken i trying to make something with Processing and PureData, and i guess what all excpetions for the relationships between other fiducials must be done by hand, reactable for the masses and for learning.
you must include the LinearInterpolationSpread node
