Support for ellipsoid(s) (to trace earth) (original) (raw)

I would like my program to (ray)trace Earth. however Earth is more like an ellipsoid then a sphere.

The program needs extensive zoom-in zoom-out capabilities, down to meter or centimeter level.

It may require 64 bit floating points.

Intersection points between ray and ellipsoid, normals on intersection points.
