Geodesic Domes with Shell and Frame
A triangle is geodesated to form a segment, which is then duplicated times around a circle to form the dome. The shell is established by the triangles, while the frame is created by laying bars along the triangles and by stellation inward. The shell can be truncated. You can vary the number of segments, degree of geodesing, distance of segments, proportion of levels and height of the dome.
