How do I implement camera axis aligned billboards?
- by user19787
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?
