Display Hyperbolic orbita

Time ago there were discussions in this forum about enabling Celestia to display hyperbola, I just wonder if there has been any recent development toward this feature. By looking into the source code, it seems that there is code in place for eccentricity > 1.0, but hyperbolic orbits cannot be drawn yet (or I missed it). Anyone know anything about this topic? It will be a useful function for Celestia to draw a spacecraft's path or a comet's orbit changing from elliptic to hyperbilic.

Well, no response :( I guess this turns up a wrong topic or bad question being asked. Close up then :wink:

It's a good topic :)

I guess the problem is that hyperbolic orbits are unbounded. The biggest hurdle in drawing them is figuring out which part of the orbit to show. Suggestions?

I would suggest to a radius from the primary (in km?) settable in celestia.cfg

If we consider a hyperbola to present space object's path, as we did with a trajectory, then how about using a beginning and ending times, just like timeline in orbit phase definition?

Just a suggestion.
