## Circular version of pictslider

Apr 10 2007 | 4:30 pm
I am making a control that converts X/Y of a pictslider to location and distance for a quad panner. When the control is rectangular, the corners come out further away than the edges. Is their a control around that limits the slider to a circle?

Hi,
If you want a circle it is good to go over the formulas for circles... pi(3.14) X r(squared) etc. and the pythagorean theorum... x(squared) X y(squared) = z(squared)
There is a quad panner that comes with max as well as others online. Is there a reason you are making one?

Hello,
jsui is probably the way to go nowdays, but if you like oldskool max, you can go the lcd way like in the cartopol helpfile, or use a combination of transparent button and pictslider:

I've already built the panner. What I need is something that reflects visually that I am dealing with a circle and not a square - like the panners in Digital Performer surround mixer.

Hi,
Sorry, I thought you wanted to do the calculation not the display...
Here is my solution for the display. I added speaker placement for my patch. You could make the lcd bigger and have a wider display of the circle.
Cheers,
Carey

i saw some really nice 4-8 channel panner with air dispersion and doppler and whatnot built in. It had a circle for its panner and you could control location of object and speaker :D
It was called ambeasonics http://www.icst.net/

Here's an example I found on my travels researching Doppler effect.
I think this might be the sort of thing your after....
Hope that helps,
Mike

Indeed, ambisonics is generally the best way to do this kind of thing, and if you don't want all of what the icst stuff offers, it is very simple to implement yourself. Just see the CMJ article by Malham and Myatt - Malham, D., and Myatt, A. 1995. "3-D Sound Spatialization Using Ambiosonic Techniques." Computer Music Journal, 19(4), 58-70.
That doesn't exactly solve the display issue, but I think it may make it easier to get there.
Best

You could also pull out the UI from this:
