Some questions pertain to 3D curves and surfaces. When an image is attached with code can one request moderator's support or in another way for viewing by 3D mouse rotation on this site ?
Producing manipulable 3D graphics as in your question is possible, as in (81104), but
- it's a lot of work,
- it needs to be done on a per-image basis,
- it needs specific hosting of large 3D data files,
- it requires the loading of a large library, and therefore
- it makes the loading of the page to take much longer, particularly for users on mobile devices.
Each of these would be fatal on its own, so there's no way this will get implemented. At present it would require both (a) extensive additional infrastructure on the site, and (b) per-question work to make the images 3D. You could envision site functionality that took Mathematica code in answers and compiled it into a 3D graphic, but that would require (a') a significant buildout of new code, to make (b') much heavier pages. You can ask the Stack Exchange team, but you can probably see what sort of answer you'll get.
