SPHERE_STEREOGRAPH_TEST01 SPHERE_STEREOGRAPH maps from sphere to plane. SPHERE_STEREOGRAPH_INVERSE is the inverse map. Check that these two functions are inverses. Map points from sphere to plane to sphere. Maximum difference for 100 points was 0.000000 Map points from plane to sphere to plane. Maximum difference for 100 points was 0.000000 SPHERE_STEREOGRAPH_TEST02 SPHERE_STEREOGRAPH standard mapping from sphere to plane. SPHERE_STEREOGRAPH2 generalized mapping: (focus and center are arbitrary) Check that these two functions can agree. Map points from sphere to plane. Maximum difference for 100 points was 0.000000 Map points from plane to sphere. Maximum difference for 100 points was 0.000000 SPHERE_STEREOGRAPH_TEST03 SPHERE_STEREOGRAPH2 maps from sphere to plane. SPHERE_STEREOGRAPH2_INVERSE is the inverse map. Check that these two functions are inverses. Using radius = 0.687452 center = (0.841560,0.734230,0.571026) focus = (0.184100,0.725775,0.370363) Map points from sphere to plane to sphere. Maximum difference for 100 points was 0.000000 Map points from plane to sphere to plane. Maximum difference for 100 points was 0.000000 sphere_stereograph_test(): Normal end of execution. 08-Jan-2022 09:49:25
