2020-07-28 18:20:58 +0200	asked a question	plot3d from sage version 9 not working in jupyter I installed sage 9.1, and also installed its kernel on jupyter. Everything else other than plot3d works fine. The behavior of 9.1 is same as 9.0, it shows a black background. If drag the mouse on it, it shows a empty frame on white background. I tried all the options, with or without switch viewer="threejs".

Everything other than `plot3d` works fine. For `plot3d`, the behavior of 9.1 is same as 9.0, it shows a black background. If drag the mouse on it, it shows an empty frame on white background. For example: `sage: f = lambda x, y: exp(-x2-y2) sage: W = plot3d(f, (-2, 2), (-2, 2)) sage: show(W, figsize=8)` I tried all the options, with or without switch viewer="threejs".
