Hi all,
I am trying to find the surface normal of an ellipsoid, given a single xyz point on a surface. I am struggling to work out how to find the tangent of an ellipsoid. I couldnt find anything obvious on google, but I may have found a clue, and that is to somehow use a cone to calculate the tangent?
If I could work out how to find the tangent of the surface should easily be able to work out the normal vector on my own.
Are there any equations I should be aware of for calculating the tangent?
Regards
James
