Hi guys.

I was checking some Gem potencialities, and find that is possible create 3D stereo images [crystal glasses] with pd. But the description of the message says that are need a especific hardware.
What i want to know is what hardware is that?

Thankx

just guessing: glasses?

Not only that, i guess. 3D LCD glasses need an input signal to tell them when you're viewing right or left image, so they can darken left or right glass. So you need a specific graphics card and the glasses that come together.
That could be this kind of hardware :
See http://www.nvidia.com/object/3d-vision-glasses.html
In doubt, search or ask the list.

Ohhh right i understand, thanks.
And about the Anaglyph glasses, i have one red/blue lens but in Pd i only manage the red/green option. It's possible change to red/blue option??

It seems that there is no option to do that. You'd have to modify Gem's source and recompile it.
