surfaceIsoparamCurve

Any isoparametric curve of a surface (in the U- or V-dimension) may be obtained by using this command.

Inline mode usage

surfaceIsoparamCurve -h
Displays the help file that summarizes the parameters for this command.
surfaceIsoparamCurve –s <surface> -p <parametric_value>
Extract an isoparametric curve in the u-dimension of the selected surface.
surfaceIsoparamCurve –u –s <surface> -p <parametric_value>
Extract an isoparametric curve in the u-dimension of the selected surface.
surfaceIsoparamCurve –v –s <surface> -p <parametric_value>
Extract an isoparametric curve in the v-dimension of the selected surface.

Interactive mode usage

Invocation
surfaceIsoparamCurve, surfaceIsoparamCurve –u or surfaceIsoparamCurve -v.
Parameters
  • Parametric dimension “u” or “v”.
  • Surface to extract an isoparametric curve.
  • Parametric value of the desired coordinate.

Example

In order to do this example, a surface must exist in the scene.

>
      surfaceIsoparamCurve
Select one surface (Press enter when done):
Tip v to change the dimension or insert the parametric value of u (0,1): v
Tip u to change the dimension or insert the parametric value of v (0,1): 0.5
>
