The plane projection is now hard coded to target until it can be
returned from imagesequencer. The dynamic ephemeris is not used for
this at the moment but will come in handy later on.
- When loading SPICE kernels, coverage for each body is stored.
- If the body does not have spk coverage a position is estimated.
- Added "pulsating" transparency levels for renderableModels with
estimated position.
- Spice manager clean up, left a few unused methods but removed a lot of
dead code.
- To support multiple missins being loaded, some errors are simply
ignored in spicemanager, for better or worse.
- Added start time and stop time as dictionary keys for renderables.
- Made RenderableTrails only show the time between gaps.
- Added but out commented vesta coordinate system swich in renderengine.
NOTE: Renderables using spiceEphemeris will give errors if body keyword
is omitted in modfile (When checking SPK coverage in position update).
Instead of spheres, the planets are now created as triaxial ellipsoids
according to the corresponding radii values in the SPICE kernels (if such
values are available). Apart from being more scientifically accurate, the
planets are shaped as the intersection functions in SPICE expects.
The textures will now also be aligned in longitude as in reality (w.r.t.
UTC) when using a texture map ranging from -180 in the left end to +180 on the
right, with 0 longitude in the middle (such as Greenwich in Earth texture)
To make modelgeometry more ready for extension in reading other file
formats in subclasses. Some minor fixes including an out of bounds error
for texture mapping with several shapes in the same file.
Added _performShading as a property and modified a spicemanager call to be able
to work with models with different names for the rotation source frame and
ephemeris body (such as 67p).
