help plz: controlling four points with one in a circle
Hi,
my math isn’t so great, and I am assuming my problem is actually pretty simple — with the right formula:
I have four points in an ambisonics "ambimonitor" object, 1, 2, 3, and 4, rotating.
1 and 3 are opposites, as are 2 and 4, a half rotation away from each way.
I want to control one point (1) and have the other three mirror the movements through the middle (zero).
my coordinates are being sent through XYZ. from 1 I multiply X and Y by -1 to get the coordinates for 3.
but what’s the formula for 2 and 4, each a quarter rotation away from 1?
I guess I need some serious math tutoring, one of these days, in the meantime, maybe someone can help me wrap my head around this
OK, I think after some inspection of the Max window I found a solution that works for me:
I inverted X and Y for point number 2, then processed *those* XY coordinates the same way by multiplying them with -1 to get point 4.
The movement look pretty, too..;)
