Dini's Surface
Dini's Surface
The surfaces in this family, which is named after Ulisse Dini, have a constant negative curvature and can be created by twisting a pseudosphere. They are parametrized by the equations , , , where and . You can view different members of this family by adjusting the values of , , and .
