- Isosamples
- ==========
-
- An isoline is a curve parametrized by one of the surface parameters
- while the other surface parameter is fixed. Isolines are a simple
- means to display a surface. By fixing the u parameter of surface
- s(u,v), the iso-u lines of the form c(v) = s(u0,v) are produced, and
- by fixing the v parameter, the iso-v lines of the form c(u) = s(u,v0)
- are produced.
-
- The isoline density of surfaces may be changed by the `set
- isosamples` command. By default, sampling is set to 10 isolines per u
- or v axis. A higher sampling rate will produce more accurate plots,
- but will take longer. This parameter has no effect on data file
- plotting.
-
- Syntax:
- set isosamples <expression>
- show isosamples
