â–  G1 Tangency. The position and tangency of surfaces is the same. This
indicates G1 (G0 + G1 or position + tangency). The zebra stripes line up,
but they veer away from one another at sharp curves.
â–  G2 Curvature. The position, tangency, and curvature of the surface edges
is the same. This indicates G2 (G0 + G1 + G2 or position + tangency +
curvature).
The stripes line up, but they do not veer away from each other at sharp
curves (because they share the same curvature). This distinction is subtle
and a little harder to discern from G1 continuity.
