Angle and distance in an XY Pad

2011-03-03T02:59:11+02:00

Thanks Senso,

It works !

The only thing, is that if you want to control angle with a value from 0 to 360 the formula should be :

x = distance * cos(angle/360*pi*2)
y = distance * sin(angle/360*pi*2)

ok, forget it , was experimenting too much thing in the same time ..
works fine

the script seems to be perfect!
to reverse the formula:

x = distance*cos(angle)
y = distance*sin(angle)

If you connect the pos-X, pos-Y out of a XY Pad to the in of the script, it should work.

It works on my side...

cool, but how do you use it..?
don't have anything from the out of the script...

Does anyone knows how I can reverse those formulas ?

Getting X-Y from angle and distance ?

I've found a solution. I don't totaly understand the maths (i've found the formula on the web), but it works.

Here is the script :

CODE:

var xIn : Tparameter;var yIn : Tparameter;var angleOut: Tparameter;var distanceOut: Tparameter;procedure init;begin  xIn := CreateParam('x',ptDataField); SetIsOutput(xIn,false);yIn := CreateParam('y',ptDataField); SetIsOutput(yIn,false);angleOut := CreateParam('angle', ptDataField ); setIsInput(angleOut,false);distanceOut := CreateParam('distance', ptDataField ); setIsInput(distanceOut,false);end;function sgn (a : real) : real;beginif a < 0  then  sgn := -1else  sgn :=  1;end;function atan2 (y, x : real) : real;beginif x > 0       then  atan2 := arctan (y/x)else if x < 0  then  atan2 := arctan (y/x) + pielse                 atan2 := pi/2 * sgn (y);end;Procedure Callback(n:integer);var x:single;var y:single;var angle:single;var distance:single;beginif (n=xIn) or (n=yIn) then beginx := (getValue(xIn) - 0.5);y := (abs(getValue(yIn) - 1) - 0.5);//angleangle := atan2(x,y) * 180 / pi;if angle < 0 then angle:= angle + 360;setValue(angleOut, round(angle));//distancedistance := sqrt(x*x + y*y);setValue (distanceOut, distance);end;end;

about the distance you can find an example in the addon named Morphusine
the match formula is

distance = /¯ [ (X1-X2)² + (Y1-Y2)²]

i will look if if i find about angle

Angle and distance in an XY Pad

Hi,

It's more a math question than an patching question, but here's the idea.

To control Ambisonic plugins, I want to get the angle (0 to 360) and the distance (0 to 1) of a ball in an XY pad, relative to the center.

Examples :
Ball at the middle = angle of 0, distance of 0.
Ball at upper left corner = angle of 135, distance of 1.
Ball at bottom right corner = angle of 315, distance of 1.

Anyone have an idea ?
