Hello,
I was wondering if anyboday can clarify this for me. I am trying to project a sphere into a plane, I am using the stereogriphic projection which I believe in cartesian coordinates is:
x'=x/(R^2-z)
y'=y/(R^2-z)
where x' and y' are the coordinates in the plane, (x,y,z) the coordinates in the sphere and R is the radius of the sphere. Am I correct using this projection?
Also if I want to have x' and y' in terms of x and y ONLY can I rewrite z=sqrt(R^2-x^2-y^2)
Thank you in advance!
