Either I have misunderstood your question, or there is no way, a circle in 3DOriginally Posted by kevd
is not determined by centre, radius and a point. You need at least two points.
I have a point a 3D space (say 0,0,0), a radius of the circle(say 2m), and know a single point that lies on the circle at a certain x co-ordinate, and have the corresponding y coordinate for the point on the circle. How can I calculate the Z co-ordinate for this point given the above parameters?
