It’s good. I have learned panda3d using this book. But it’s a bit outdated. The latest panda3d version was 1.9.x at the time I have read this book. Most of the examples still works even in panda3d 1.10.x
This book basically a collection of solutions for some popular problems. But you can still read this as a regular book from beginning to the end, so you could understand how you can use panda3d. However, this book doesn’t teach you python, general game development related things and pipelines.
