26 February 2022 01:27:25 PM SPHERE_STEREOGRAPH_TEST C version Test the SPHERE_STEREOGRAPH library. 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. RMS difference for 100 points was 2.27002e-17 Map points from plane to sphere to plane. RMS difference for 100 points was 6.98086e-18 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. RMS difference for 100 points was 2.66338e-17 Map points from plane to sphere. RMS difference for 100 points was 1.12771e-17 TEST03 SPHERE_STEREOGRAPH2 maps from sphere to plane. SPHERE_STEREOGRAPH2_INVERSE is the inverse map. Check that these two functions are inverses. Using radius = 0.996643 Center: 0.561695 0.415307 0.0661187 Focus: 0.218418 0.956318 0.829509 Map points from sphere to plane to sphere. RMS difference for 100 points was 3.23851e-17 Map points from plane to sphere to plane. RMS difference for 100 points was 3.32351e-17 SPHERE_STEREOGRAPH_TEST Normal end of execution. 26 February 2022 01:27:25 PM
