Bug Description
After importing comet from MPC, it's position can be found with F3, but no actual object is shown.
Drawing is canceled in the following line :
if (!orbit-
[comet.cpp, line 463]
Further investigations tell us that time_at_pericenter for this object has negative value.
The comet is added to the ssystem.ini as usual:
[c2014q2(lovejoy)]
orbit_SemiMajorAxis = 582.1349
orbit_ArgOfPeri
orbit_Epoch = 2457000.5
slope_parameter = 8.4
orbit_AscendingNode = 94.9754
type = comet
orbit_MeanAnomaly = 359.9963
name = C/2014 Q2 (Lovejoy)
albedo = 0.04
orbit_MeanMotion = 7.02e-05
orbit_Eccentricity = 0.997783
tex_map = nomap.png
color = 1.0, 1.0, 1.0
absolute_magnitude = 4
orbit_Inclination = 80.3029
parent = Sun
lighting = false
coord_func = comet_orbit
radius = 5
There are two possible temporary solutions:
- add the following line:
orbit_
- replace
type = comet
with
type = asteroid
I cannot reproduce this in current trunk, comet is nicely rendered. What version do you use?
