Broken orbit rendering #8

Open petronius opened 8 years ago

petronius commented 8 years ago

Orbit.from_true_anomaly() will return a v_position with a flipped sign on the y axis in many cases. This likely due to calculating the eccentric anomaly from arctan() (and not arctan2, thus the angle ending up in the wrong quadrant), but I am not sure.

This is only a problem with the orbit plotting code, though, and doesn't affect actual spaceship movement.

Could also be related to the rendering of the orbit. Under certain cases broken orbits appear to rotate the camera when the focus isn't on the origin.
