Title: GA Continuity

Abstract: Using geometric algebra, the outer product of two vectors yields a planar element (a bivector) that readily characterizes tangent planes. One property of bivectors is that while they have an area, their shape is undetermined. This has the right feel for characterizing a form of tangent plane continuity between surface patches, where we would require that two patches have equal bivectors (tangent planes) along a common boundary. In this talk, I explore this idea of GA Continuity as it applies to triangular Bezier patches.
