Showing the lines of curvature on a non-rotationally symmetric ellipsoid and the singularities at the umbilical points. The principal net appears as the intersection with the ellipsoid of its confocal family of quadrics.

Same as Confocal Quadrics 2 - but also showing the intersection with the XY-plane, which generates a system of confocal conics.

A triply orthogonal system of surfaces. Through each point in space there passes three surfaces from this system and they are mutually orthogonal.

In this video I discuss the sphere in the same way I will discuss other quadric surfaces later on. (The idea being that you already understand the sphere but may not be used to the idea of graphing it using a bunch of slices.)
We show how to compute the arrangement on an ellispoids induced by two other ellipsoids that intersect the former. The video show the steps taken by a sweep line paradigm.

The video is a description of our work "Manicone" - a Java application displaying a humanoid form in four spatial dimensions.
