[vtk-developers] Wiki example strangeness

[Andrew Maclean]

Continuing on ...
With respect to the first image, I suspect that this may be fixed in the
master by your submission: http://review.source.kitware.com/#/c/16872/
and/or http://review.source.kitware.com/#/c/16873/

As for the differences between the hill shapes in Windows and Linux, the
same RNG needs to be used in all machines. I'll look at using one of the
ones in vtkMath.h at some stage. There is an option to turn off random
generation and generate regular shaped hills, but it is pretty boring.
