Rendering objects over large distances is common for geospatial programs, and when done incorrectly, the objects may visually jitter. Here, an object is made up of any combination of triangles, lines, and points, like a 3D model. The problem becomes more noticeable as the viewer nears the object. The following video demonstrates this using STK. (Note that I had to modify STK as it does not ordinarily exhibit jitter.)
Rotating about the space shuttle from far away, there is no jitter. After zooming in, the jitter is readily apparent. In this blog entry, I'll discuss the cause of this problem and the solutions used in Point Break and STK.
