[vtkusers] help on entity modification/transformation

[M.Hardikar at asu.edu]

Dear Users,

I am new to VTK environment and I would like your help on the following
operation that I want to carry out.

In my code, I read in 3 different CAD files. Once they are read in, I want to
selectively make changes to any one of the 3 files. I want to know if I can
traverse the vtkPropCollection and one by one retrieve each of the files that
I read in for modification?

If it is possible, could anybody share the code with me?

Also I would like to have some information about carrying out transformations
on entities selectively. 

Any help would be valuable.

Regards,
