CAI of Stereographic Projection

Abstract

Stereographic projection is widely used in mineralogy, structural geology, geophysics and rock mechanics. However, it may be very difficult for the students who have not been learned solid geometry to get the three dimensional image from the stereographic net. Then the author coded the CAI program showing visually both spherical projection and the Wulff's net. This program is applied to the CAI for the paleo-stress fields calculated from the conjugate fault sets.
