Place a piece fo tracing paper over the Wulff net and draw on it the index mark at the north pole of the net as well as the basic circle. Mark on this tracing paper all of the poles shown in order to obtain a 100 standard projection. Now rotate this standard projection about the north? south polar axis by 45°, so that the [110] pole moves to the center of the stereographic projection. In this rotation all of the other poles should also be moved through 45° alond the small circles, of the Wulff net, on which they lie. This type of rotation is facillitated by placing a second sheet of tracing paper over the first, and by plotting the rotated data on this sheet. This exercise shows one of the basic rotations that can be made with a stereographic projection. The other primary rotation
involves a simple rotation of the tracing paper around the pin passing through the centeres of both the tracing paper and the Wulff net. What will be an ideal response?
