In general, conic curves are defined by their radius R_0 and the conic constant k in the following way:
y^2 + (k+1)*x^2 -2R_0*x = 0, with x/y being the points on the conic curve.
The conic parameter k defines the shape of the curve with e.g.,
k=0: circle
k=-1: parabula
etc.
How does the Fusion parameter Rho relate to the conic parameter k and the radius R_0?
Alternatively, is there a way to use mathematically defined curves in Fusion?
