GBT Visualization

The following four images were produced using the new AVS "network", which allows the displaying of lines in the structural model as tubes while simultaneously displaying the "quads" (four-sided polygons) which are also present in the original dataset.

This first scene is looking almost straight down, from the tip of the prime focus boom (i.e., the focal point of the primary), toward the roof of the feedroom and the inner edge of the big dish. We see that the line of sight to the innermost panels passes close to the front top edge of the room, and that the proposed rangefinders will be even further from the edge of the beam. The tubes projecting from the top of the feedroom are modelling the turret, and the secondary focal point. Note how the new AVS network has the curious side-effect that the lines are rendered along the axes of the tubes.

The second scene is an oblique view of the feedroom area from below. The prime focus boom and the subreflector actuator model are above the room, and there are four 0.5 m cubes on the edges of the roof of the feedroom, representing suggested locations for the rangefinders.

The third scene is an overview of the telescope model from the side, as seen from several hundred meters distance and a height of about 100 meters. There are 18 cubical objects in the scene, with sides 20 inches (0.5 m) long. The telescope is pointing at the zenith. The pseudocoloring of the panels of the dish is coding the magnitude of the displacement vector of the nodes due to gravity acting on the dish. The grid spacing 1000 inches.

The fourth scene is another oblique view of the feedroom area, but this time from a point at about the same height as the room. In this scene the two cubes at the rear corners of the feedroom have been moved downward and outward slightly, so that they are at the edge of the roof, and about a meter from the front of the feed legs.
