[vtkusers] implicit functions other than quadric

[David.Pont at ForestResearch.co.nz]

Hi,
  derive a class from vtkImplicitFunction and implement EvaluateFunction
and EvaluateGradient.
It sounds like you want to evaluate arbitrary functions so I would
recommend setting up a way for the Evaluate functions to call a user
defined function (there are examples of this kind of thing in vtk).
Follow vtk style (http://www.vtk.org/contribute.php) and submit it for
inclusion in vtk once it is working, this would be useful.

Hello,
I am looking for a method to visualize implicit functions like
F(x,y,z)=sin(x)+cos(y)*2+exp(z)
F(x,y,z)=x^5+y*z^3+x*y
I cannot find any suitable Class under "vtkImplicitFunction" that can solve

this problem. But, I don't believe vtk cannot handle such functions which
are
mathematically simple.

Anybody can give me a hint how to do it?

Thanks a lot.
