- are the ellipsoid's main axes arbitrary? or parallel to some coordinate axis? in world coordinates or in local coordinates?
- is the triangle specified by its three vertices or some other way?
What information exactly do you want to compute?
- a boolean "does (not) intersect" can be computed analytically, as described here:

- distance to an ellipsoid is surprisingly complex to compute:
