SurfLab Controls

Choosing "Controls | SurfLab" on the SurfLab menu box brings up the SurfLab controls panel, where you specify the parametrization of the surface you want to see. The parametrization is a map into one of R2, R3 or R4:

The entries in the SurfLab controls panel are:
  • var1, var2 -- the names of the parametrization variables. By default these are u and v.
  • dimension -- the dimension of the target ambient space, 2, 3 or 4.
  • x1, x2, x3, x4 -- the functions parametrizing the surface. Use as many of these as the dimension.

The syntax expressing the parametrizing functions x1. . .x4 is Mathematica-like; see parser syntax for details.
