Space Features

Most Important

• Sensor improvements. Test cases:
  • Narrow six-arc-second field-of-view. Display condition to draw a polyline?
  • Narrow sensor like a fan
  • Wide sensor with a cap
  • Custom sensors with 100s to a 1,000 points
• Sun size. #769
• Night time. Overlaps with night lights and atmosphere work
• Fuzzy ellipsoid lines. #899

Important

• Render moon with right size and right lighting. We already have the moon position, #677
• Lighting conditions: umbra, penumbra, and umbra cone
• Mousewheel 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?)

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)
