I am trying to make an Axis Aligned Billboard with Pyglet. I have looked at several tutorials, but they only show me how to get the Up,Right,and Look vectors. So far this is what I have:
target = cam.pos
look = norm( target - billboard.pos )
right = norm( Vector3(0,1,0)*look )
up = look*right
gluLookAt(
look.x, look.y, look.z,
self.pos.x, self.pos.y, self.pos.z,
up.x, up.y, up.z
)
This does nothing for me visibly. Any idea what I'm doing wrong?
