Trajectory path display #8

Closed gabrielfougeron closed 9 years ago

gabrielfougeron commented 9 years ago

I suggest a new (non-trivial) GUI feature : trajectory display. The trajectory of planets could be displayed, and remain on screen for a while. To acheive this, the following questions must be adressed :

Shape of trajectory (piecewise straight lines ? higher order polynomials ?). Visually pleasing result needs continuity (?), maybe even C¹ or higher.
Does the line fade away after a time ? What time (to be configured) ? Clear button ?
Interaction with zoom / movement of camera.
Interaction with rewind

Fixed. A bug remains, reported on #31.
