loading vtk libraries into vtk

[David Gobbi]

Hi Miguel,

There is an (undocumented) method for loading vtk into wish:

cd vtk/tcl
make vtktcl

This will build a 'vtktcl' extension.  You must copy it into tcl's
search path, which generally includes /usr/lib, /usr/local/lib, or
whichever 'lib' directory tcl is installed in.  It generally does
not include the current directory.  To load it, use

load vtktcl

If you get an error, then vtktcl (note that it does not have a '.so'
on the end) is probably not installed in the right place.
