Coord system question.

2 quick questions.

First, what direction is the z axis in opengl?
Obviously if you are looking into a monitor, Possitive x is to the right, Negative x is to the left, Possitive y is up, negative y is down. SO, is the Possitve Z pointing into the screen, or pointing at my eyes?

Secondly, what is the default orientation vector?? I know its looking down the z, but what direction, looking down the pos z, or the negative z??

Thank you.

Positive z axis is pointing at your eyes and negative is pointig away from you.

Default orientation vector is looking down the negative z axis.
