Title: Next to useless if you actually want to learn to use VTK Product review: If you're looking for a book to learn to use VTK, this is practically useless. The language is explained only incidentally, and in very little detail. the book mostly concentrates on computer graphics theory (which is done much better in other books) and visualisation, which it treats fairly well. Would you say this review depicts the product in a flattering or unflattering light?
