Space Features

Most Important

• Narrow six-arc-second field-of-view sensor. Display condition to draw a polyline?
• Bent ellipsoids.
• Fuzzy ellipsoid lines. #899

Important

• Lighting conditions: umbra and penumbra cones
• Sun and moon labels? #1218
• Mouse wheel is slow for long view distances. #1011
• CZML support for stored views
• Draw two vectors with an arc for the angle and an annotation

Less Important

• Textured plane aligned with sensor boresight (use a model?)
• Draw individual stars from a database.

Done

• Ability to show Earth-centered view in ICRF instead of Fixed. - #825
• Viewing in LLVH - #531 #818
• Render sun.
• More precise sun position. #391
• Inertial frame
• Polyline - per-vertex color for passes. Will [materials] (https://github.com/AnalyticalGraphicsInc/cesium/wiki/Fabric) on polylines work?
• Ellipsoid improvements
  • Eliminate jitter - #392
  • Zoom inside - #390
  • Covariance interpolation (in czml-writer)
• Sun size. #769
• Render moon with right size and lighting. We already have the moon position, #677
• Night time. #1251
