This is a cone entity, and now it intersects with the ground, forming a circular intersection line. Is there a method to obtain the collection of points that make up this intersection line? If the entity has a more complex shape, would this approach still work?
One distinction is probably important: Are you looking for the intersection between the cone and the ellipsoid (that is used for approximating earth), or are you looking for the intersection with the actual terrain data?
Computing the intersection with the ellipsoid could be possible, analytically (it may be math-heavy, though). Computing the intersection with the terrain data will raise a bunch of questions (more on the ~“engineering level”).
(I probably cannot give “The Answer”, from the tip of my head, either way, but for those who are trying to answer, this will be a first, important question)
