..., +}. On the contrary, the vector T is ( Fig. 5.4 ) Δ T = {–, 0, –}; hence, k m will become positive. Traditionally, in 3-D geometry, positive curvatures are associated with convex bodies. Concave bodies (hollow shapes) correspond to negative curvatures. This practice is opposite to two-dimensional...
