It's said that a 3D object is several 2D objects stacked on-top of each-other to create thickness but how can several 2D planes with a thickness of 0 add up to be something that has thickness and thus create a 3D object?
This article may be improved by adding a mention of Graphs (ie networks of nodes or connectivity information) that have dimension of 3 through Dimensional_analysis. This type of structure is an alternative to the axis-based way of thinking about the dimensionality of space in the universe. See also Fractal dimension on networks.

The article's first picture is badly in need of proper formatting to get rid of the "jaggies". I suggest conversion to SVG. - KitchM ( talk) 21:44, 10 October 2009 (UTC)
This space is above (in dimension) the sphere or the 2-sphere:
If the 2-sphere lives in her own but also can be viewed embedded in and is defined as such that and .
And the hypersphere -very well known to a real topo-geometer- is: a set consisting of point in the 4-dimensional euclidean space which are equidistant to the origin, usually we take distance one. In other words: such that, if then . So, i don't know why unsavvy geeks think they know and write lies, and only producing that math look stupid... well, that it seems a law in these wikiplaces. -- kmath ( talk) 22:28, 25 September 2011 (UTC)
Just as a 3D object casts a 2D shadow (kinda) should it be noted that a theoretical 4D (not time) object would cast a 3D shadow? (kinda.) or is this all too original researchy? 74.132.249.206 ( talk) 11:13, 15 October 2011 (UTC)

I undid some clear vandalism, but have no idea what the article is supposed to look like. I just did this 'en passant' and have other things I must do. Can some Samaritan look this over? DeepNorth ( talk) 14:16, 11 November 2012 (UTC)
This article should be merged with space as that article is also explicitly dedicated to three-dimensional space. Rgdboer ( talk) 22:26, 5 November 2013 (UTC)
Yes, I see your point: parts of the other page having reference to physicality would not apply to this page. The WP:namespace logic is clear, and have taken down the merger tags. Thank you for clearing that up; three dimensions need not be materialized. Rgdboer ( talk) 02:08, 24 March 2014 (UTC)
@ Rgdboer and Pikachu Bros.: Titles of articles should reflect their content. So I'd like to rename the present article to Three-dimensional space (mathematics), which is already tagged as the main page of section Space#Mathematics; then redirect Three-dimensional space to the broader-concept primary-topic page about three-dimensional space in general (physical, mathematical, etc.), which is the Space article.

What exactly is Breadth? I know an 3 dimensional object top-down has depth and a 3 dimensional object looked at sideways has height... But what is breadth? Breadth and Length both point to the same article called "Length". I find that sentence very unclear. please clarify it. 195.177.247.202 ( talk) 14:37, 7 August 2014 (UTC)
A three dimensional object can be described by:
Usually one of those is a good fit for each of your dimensions. Sometimes two fit, in which case you get to make a choice. Sometimes none fit, in which case you should use breadth.
A loaf of bread, for example, has length, breadth and height; while a slice of bread has thickness, breadth and height. — Preceding unsigned comment added by 64.178.132.12 ( talk) 05:43, 22 April 2015 (UTC)
The top diagram has a note which says "(See diagram description for correction.)" Why does it need correction? It looks okay to me. Either the diagram should be corrected or the parenthetical note should be deleted. Wahrmund ( talk) 16:10, 16 January 2016 (UTC)
@ Fgnievinski: I propose that the title of this article be reverted to three-dimensional space for the following reasons:
Please discuss. If there is consensus to revert the name, I think an admin may have to do it. Biogeographist ( talk) 16:23, 3 August 2016 (UTC)
Alright, please go ahead with reverting the renaming, but let's leave the hatnote in place, indicating that the present article is not meant to cover everything about three dimensional space, e.g., for non mathematical aspects, please see Space. fgnievinski ( talk) 03:57, 5 August 2016 (UTC)
The result of the move request was: Moved (non-admin closure) — Andy W. ( talk · ctb) 17:15, 13 August 2016 (UTC)
Three-dimensional space (mathematics) → Three-dimensional space – Parenthetical disambiguation was added to the article title last year during a content merge, but discussion on the talk page has concluded that the parenthetical disambiguation is not necessary; among other reasons, the largest number of incoming links are redirects from Three-dimensional space. See discussion on the talk page above this template for further reasons. Biogeographist ( talk) 14:49, 5 August 2016 (UTC)
The article seems a tad bit short and doesn't seem to explain about 2d drawings faking 3d or stuff like that, but once you add that I think this image would be good for illustrating that.

I Propose that Three-dimensional_graph merges here. 3D graphs could be added to this article =)
Here's some stats: (as of the date of this post.)
