Orion in 3D

This animation begins with a pan across the sky to Orion, and the lines of the 2D stick figure constellation are drawn in. As the point of view slowly begins to circle around the centroid of the stars, the stick figure quickly “distorts” into a  3D structure. The viewpoint backs up to keep the entire figure onscreen as it move through a complete circle. At the end of the circle, the camera zooms to finish at the location of the Earth/Sun (to avoid an obvious distraction, the Sun is not included in the visualization).

During the final zoom in, notice how Sirius grows in apparent brightness (bottom of frame, just left of center). While Sirius is the brightest star in our night sky, a major contribution of its apparent brightness comes from its proximity to the Sun.
