2011-09-28: What's New in DAVID-Laserscanner Version 3.1.0

2011-09-28: What's New in DAVID-Laserscanner Version 3.0
The changes in DAVID 3 vs. 2 are so numerous that we can not enumerate all in detail.
Just to name a few:
- Full integrated Structured Light (SL) that makes scanning faster and easier. For this method you can use a standard video projector instead of the line laser. The video projector is connected to the PC and DAVID 3 uses it to illuminate the object with several stripe patterns. Click “Start” - wait a few seconds - see 3D result on screen.
- A completely new user interface, which we think is more versatile, flexible, and beautiful.
- An integrated auto update.
- Improved memory handling → can handle more huge scans.
