Query: Is this book a joke?

A waste of money, a waste of time reading it, an appalling waste of trees cut down for the paper.This author has no idea how to create anything in 3-D applications. The software used to make these 'models' (and I use the word loosely here) are high-end, professional software. His techniques are sub-standard at best, mostly downright sub-amateur. If anyone actually used the techniques used in this book, they would be laughed out of their design-studios and sacked immediately.Terrible book - the best place for it is in the trash can.
