Thank you for directing me to the SampleField module.
I would like to call the SampleFieldRandomAlgoT::execute() method from
another module, but I am having some trouble.
This is basically what I'm trying:
ProgressReporter *pr = new ProgressReporter();
FieldHandle myField = SampleFieldRandomAlgoT<SCIRun::TetVolMesh>::execute(pr,
someFieldHandle, 10, 1, "uniuni", 0);
I am getting this error message:
error: cannot call member function `SCIRun::FieldHandle
SCIRun::SampleFieldRandomAlgoT<Mesh>::execute(SCIRun::ProgressReporter*,
SCIRun::LockingHandle<SCIRun::Field>, unsigned int, int, const std::string&,
int) [with Mesh = SCIRun::TetVolMesh]' without object
Thank you for your help,
Elisha

The SampleField module does this.

The problem is that in the TetVolMesh some nodes are closer together, and

In order to make this process more random, I would like to get the
