The book's cover
I think the book is great. It has been very useful to me, and I would recommend it to anyone who wants to do physics animations with Blender. The book has very in-depth information, along with some information that is hard to find online.
In the book, there is information about the fluid, rigid body and soft body simulations. There is also information about the particle system, which really helped to increase my understanding of particles in Blender. There are a lot of images in the book, which helps to visualize what is being explained. The CD included with the book has the source files that were used to create all the images.
It explains concepts that can be difficult to understand, but the way they are presented is very clear and comprehensible. Though it explains things clearly, I sometimes found the information hard to follow in a way. I would be reading about one aspect of soft bodies, and then it would start explaining something completely different about them.
The book not only covers the physics, but also making them look good. After it explains how to set up a simulation, it explains how to set up the materials and make it look great. I think that is an essential part of any book on Blender.
To conclude this review, I would recommend this book if you are looking into Blender physics.
