Hi,
I was watching this line tutorial by paketa12 (line transfer in Touchdesigner - YouTube). He is explaining about finding the vector direction of pixels(time: 3:35 - 3.57). As far as I understand, he is using polar coordinates to find the direction. The angle value(theta) is various values of “R” channel and by taking cosine and sine of those values to get the “point” (x, and y values). But where is the distance between the (0,0) and the pixel (“r” in polar coordinates)? Kindly clarify the portion from 6.51 to 11.04 where he is explaining these position and direction of pixels.
Thank You
