Hello, I've compiled a list of changes to the graphics component of Sage in 9.2 along with some brief descriptions. I'm most familiar with the Three.js changes from Paul Masson and myself, so hopefully I didn't miss any others or misunderstand their intent.
As I don't yet have an account on the Sage wiki to be able to edit, I've attached a text file with the (hopefully correct) markup. I will look into the process of getting a wiki account.

== Graphics == === New features === * Specify the rectangle in which to draw a matrix using the new `xrange` and `yrange` options of `matrix_plot`. For example, to draw a matrix in [0,1]×[0,1] instead of the default [-0.5,4.5]×[-0.5,4.5]: `matrix_plot(identity_matrix(5), xrange=(0, 1), yrange=(0, 1))`. [[https://trac.sagemath.org/ticket/27895|27895]] (Markus Wageringel) * Set the initial camera orientation in Three.js plots using the new `viewpoint` option. Pass it a list/tuple of the form `[[x,y,z],angle]`, such as that provided by the existing `Get Viewpoint` option accessible from the menu button in the lower-right corner of a Three.js plot. [[https://trac.sagemath.org/ticket/29192|29192]] (Paul Masson) * Save a 3D graphics object directly to an HTML file that uses the Three.js viewer, similar to how you would save a PNG image: `G.save('plot.html')`. [[https://trac.sagemath.org/ticket/29194|29194]] (Joshua Campbell) * Produce an interactive 3D animation that you can pan, rotate, and zoom while the animation is playing using the Three.js viewer. A slider and buttons for controlling playback are included on the page by default. To use this new feature construct an animation as you normally would, passing a list of still frames to the `animate` function, then call the `interactive` method. For example: {{{ def build_frame(t): """Build a single frame of animation at time t.""" e = parametric_plot3d([sin(x-t), 0, x], (x, 0, 2*pi), color='red') b = parametric_plot3d([0, -sin(x-t), x], (x, 0, 2*pi), color='green') return e + b frames = [build_frame(t) for t in (0, pi/32, pi/16, .., 2*pi)] animate(frames, delay=5).interactive(projection='orthographic') }}} [[https://trac.sagemath.org/ticket/29194|29194]] (Joshua Campbell) === Implementation improvements === * Points are now sampled exponentially when `scale='semilogx'` or `scale='loglog'` is specified. This decreases the number of points necessary for an accurate plot (and also increases the chance that the default number of points will produce an acceptable plot). [[https://trac.sagemath.org/ticket/29523|29523] (Blair Mason) * Points and lines are now ignored in STL 3D export. [[https://trac.sagemath.org/ticket/29732|29732]] (Frédéric Chapoton) * Three.js has been upgraded to version r117. [[https://trac.sagemath.org/ticket/29809|29809]] (Paul Masson) * Long text is no longer clipped in Three.js plots. Multi-line text is not yet supported but is in the works. [[https://trac.sagemath.org/ticket/29758|29758]] (Joshua Campbell) * JSmol's telemetry functionality has been disabled. It will no longer phone home when, for example, using `viewer='jmol'` in a Jupyter notebook. [[https://trac.sagemath.org/ticket/30030|30030]] (Joshua Campbell) === For developers === * Clarified that example Three.js plots in the documentation should use the `online=True` viewing option. [[https://trac.sagemath.org/ticket/30136|30136]] (Paul Masson)
