Dear Sage-dev, This is a poll to make three.js (https://threejs.org/) the default 3d viewer in Sage, in replacement of Jmol (https://sourceforge.net/projects/jmol/).
Indeed, thanks to the work of Paul Masson, the three.js 3d viewer is doing a very good job in displaying Sage 3d plots, as you can see in these examples taken from Sage reference's manual: https://nbviewer.jupyter.org/github/egourgoulhon/SageMathTest/blob/master/Worksheets/sage_reference_threejs.ipynb You can rotate/zoom the 3d view with the mouse and, by clicking on the small black arrow at the bottom right of the view, you can download a png screenshot. Other examples of three.js rendering can be found in this notebook devoted to anti de Sitter space: https://nbviewer.jupyter.org/github/sagemanifolds/SageManifolds/blob/master/Notebooks/SM_anti_de_Sitter.ipynb For more information about the three.js renderer in Sage, see https://doc.sagemath.org/html/en/reference/plot3d/threejs.html The discussion about having three.js as the default viewer is taking place in the ticket https://trac.sagemath.org/ticket/22408 This ticket also contains the git branch to perform the change if decided. Here is a discussion summary: in favor of three.js, we have - three.js, which is based on the WebGL API, displays 3d plots faster than Jmol, and with a better quality - 3d plots rendered with three.js can be publicly shared via nbviewer.jupyter.org, contrary to those rendered with Jmol, which appear as blank spaces, cf. this test notebook: https://nbviewer.jupyter.org/github/egourgoulhon/SageMathTest/blob/master/Worksheets/test_3d_view.ipynb - three.js enables to label the plot axes (via the option 'axes_labels', the default of which is ['x', 'y', 'z']); on the opposite, there are no labels on Jmol plots and the option 'axes_labels' is ineffective, which looks like a serious drawback for a mathematical software... - Jmol causes many troubles to Sage packagers (see #22408 <https://trac.sagemath.org/ticket/22408> for details); for instance in Sage 8.8 console, Jmol display is broken on recent Debian-based distros (e.g. Debian Buster and Ubuntu 18.04), due to a JRE issue; fortunately this is fixed by https://trac.sagemath.org/ticket/25026 On the con side, there are - the current lack of non-interactive conversion of three.js views to static png figures (in interactive mode, the black arrow mentioned above does the job). As a result, the png figures in the reference manual will still be generated with Jmol, as proposed in #22408 <https://trac.sagemath.org/ticket/22408> - some minor opacity issues (see #22408 <https://trac.sagemath.org/ticket/22408> for details) Given the above elements, please vote!
