Is it possible to programmatically get a list of 2D and/or 3D Graphics Primitives?
Edit: Indeed, there is an answer to this question here. It is, however, much focused on a function checking that the object is a primitive, then on the one giving a list of such.
There is a list of primitives in the answer of A. Popkov. Not a function as I asked, however. Its disadvantage is that it is related to the 10.3 version and does not communicate what happened since.
In the answer of Edmund, there is a function that must return a list of primitives. On Mma 11.2 it only returns a part of primitives. For example, such a primitive as Point is missing for me, though it is present in the original answer of Edmund.
I conclude that no satisfactory answer to my question still exists.
