Do you know anything else about the ellipse? It's pretty tough if only the center is known.
Assume we have an ellipse (positioned somewhere in 3d space) and I also have a vector pointing towards the center of the ellipse. How can I specify in 3d rectangular coordinates the directions of the major and minot axes knowing the center of the ellipse?
Thanks for your reply. No I dont know anything else. I only know that there exists a vector that points towards the center of the ellipse. From this I would like to find out the major and minor axes directions.
Say for example that the center is at [1 0 0].
