Recently, LMI released a very helpful guide to understanding 3D.
"At LMI Technologies, solving complex problems in a simple way is the
philosophy that guides our passion for developing leading edge 3D
technologies. It is because of that guiding philosophy, we have created this eBook.
This guide is a high-level approach to the very technical world of 3D scanning. The concepts, principles, and devices presented here within have been generalized to give those new to 3D scanning a starting point. However, this guide is not just for newbies. It is also for those in-the-know who need to educate or present 3D to those outside of the engineering world.
As a first edition, this is only the beginning for this guide. In coming editions, we will cover more ground in the very fast paced world of 3D scanning technologies. Because this guide is for everyone, we invite you share with us any topics of interest for future editions. You can reach us at firstname.lastname@example.org.
We hope that you enjoy this simple guide."
