hi, i want to create a very basic patch using jit.gl.sketch where a line rotates from the center point around a circle (where r=0.8). it's been years since i took math, and i'm really uncertain of how to calculate my x,y destination coordinates. here is my basic patch. any help is much appreciated.

use poltocar. note i've changed your right (angle) slider to send out float values from 0-2pi
and you need to use the trigger object to update the poltocar calculation when changing the angle
perfect! thx terry, interesting to see the use of the cartopol/poltocar objects outside of fft~ processing. i really wish my understanding of math was more thorough.
