hi, i got my vbo to work fine. i draw it in the xy plane with draw elements and rotate about the y axis and it stays in the xy plane as expected.

however, when i make an image and draw it with draw pixels into the xy plane and rotate about the y axis, it sorts slides back and forth, staying the same size, with it's lower left corner pinned into the xy plane (i.e. it's normal is pointing out of the screen towards the user).

is this behavior correct?

thanks
