Pseudosphere and half-sphere - surfaces with negative and positive Gaussian curvature

The half-sphere and a pseudosphere are surfaces of constant positive and negative Gaussian curvature. These models can be used for a “tape-trick” visualization of geodesics. See “ Visual Differential Geometry ” by Tristan Needham for…
