If I then have a point in the grid I want to test if that point is in one of the spirals. I acutally want to test if it within a certain range of the spirals but determining if it is on the point is a good start.

Witryna1 sie 2014 · The equation for exponential-style spirals is. r = a e b θ. What that means is that if we consider the angles θ, θ + k then. r ( θ + k) r ( θ) = e b k. Which means the ratio of the radiuses is a constant for fixed difference between the angle. So as an example lets say you had your radius at 1 cm and you draw a point.
