Quad Buffer

Hi,
I'm trying to use ARToolkit with stereo feature. libARgsub.lib has some 
function like:

argDraw2dLeft();
argDraw2dRight();

Do I have to use those in place of

argDrawMode2D();

?

Looking up into the code I saw that the library uses Stencil Buffer instead 
of Quand Buffer, why?
Anybody can tell me if there is use of quad buffer somewhere in the 
ARToolkit libraries?

Thank you.
Daniele

Hi, I just finished implementing stereo display using quadbuffer inside ARToolkit. If you are using one input camera for stereo display, there are no existed methods in ARToolkit that will allow you for a direct call, but the good news is that glut supports quadbuffer by setting the STEREO mode, then you can operate on the projection matrix to have two frustrums separated by eye separation. There are some good sample examples in the web for reference. The methods you mentioned (argDraw2dLeft(),argDraw2dRight()) is designed for HMDs, which needs to calibrate two cameras.

I've a problem using quad buffer. The model is displayed fine but it there is an offset with the marker and it changes if I move the marker. I tryed to apply some transformation to the object but nothing is changed. What kind of transformation have I to use in place of that used with mono and fetchd with arGetTransMatCont()?
