USING 3D SHUTTER GLASSES

Nanosaur II looks absolutely amazing with shutter glasses! It’s a similar experience to using

the anaglyph glasses, but there’s no color distortion and the image is crystal clear! It’s like

looking through a window into a real 3D environment.

A few things to note about shutter glasses:

1. You need a at least 64MB of VRAM on your computer to use this mode, so some older

machines with low-end 3D chips won’t be able to do this.

2. Shutter glasses will only work on CRT monitors with a VGA connector. They WILL

NOT work on LCD displays. Additionally, your CRT monitor must be capable of

refresh rates of 85hz or more.

3. You should be careful when using shutter glasses as the rapid flickering can trigger

seizures in epileptics.

BUYING A PAIR

There was a time when it was easy to buy a good pair of inexpensive shutter glasses, but ever

since the demise of the entire Virtual Reality industry in the late 1990’s they have been

relegated mainly to the bio-medical fields where they are used for things like molecular

visualization. A pair of shutter glasses which may have cost $100 back in 1995 now costs

$1000. However, if you look around on places like Ebay you can often find people selling their

old ones for much, much less. You just have to be sure you’re buying both the glasses and the

controller / emitter for them.

There are several types of shutter glasses out there, but the only kind that will work with

OpenGL on Mac OS X are the “blue-line sync” type. So, before purchasing a pair of shutter

glasses, be sure they are the blue-line sync type. Not the interlace sync, software sync, or any

other type of sync. Only blue-line sync glasses will work.

The only company still in business that we know of that sells blue-line sync glasses is

StereoGraphics, but it’ll cost you over $1000.
