Re: [Celestia-developers] Light travel time support

Clint:

I have implemented the /manual/ subtraction for LT-delay exactly for the
reasons Chris mentioned above. If I consider the level and interests of the
average Forum member as representative, I conclude that most just like to
browse through space without looking much to LT-delays and the like. 

Notably with the introduction of the /multiview/ feature, you sure have noticed
that it can become quite CPU-intensive with several views active. So there does
not seem to be much room for vasting CPU power! 

But clearly the automatic incorporation of LT-delay is rather trivial once time
is moved to the Observer class, we may introduce an option in the GUI for
continuous implementation of LT-delay for an appropriate subset of selections.

Since you are not using the /most convenient/ KDE interface, you will also not
have noticed the handy implementation of the LT-delay subtraction in the time
setting dialog along the lines I proposed some time ago.
The idea being that observing time-critical events always will involve setting
the time somehow through this dialog. So no extra effort to hit the LT-subtract
button if desired. Also it is instructive to /see/ explicitly how long the
light actually travels...Have a click:
