PPTK, setting camera position

Question

I try to setting camera position of pptk, with this method:

xyz = pptk.rand(100, 3)
v = pptk.viewer(xyz)
v.set(lookat=[0,0,0])

this working well, the camera position change. But when I left-clik on it, to move the point cloud, the camera position return to the original position

Do you have an idea how to maintain the camera position Thank you

Answer 1

Please send the look-at coordinates as a tuple (0,0,0) instead of a list [0,0,0].

v.set(lookat=(0,0,0))

Answer 2

I found this bug too. I'm currently working around it by first using the mouse wheel to move in/out on the point cloud before clicking; then the look at position doesn't change.
