[edit] Precision Disambiguation
Hmmm.. I agree that precision needs to be disambiguated [1], but I don't think accuracy and precision is the right meaning. In that sense, precision is the repeatability of measurements, or degree of mutual agreement between values... But what is meant in the z-buffer article is more about the ability to *distinguish* between two close values. This seems more related to resolution, actually, but that article doesn't seem to have the precise (heh) meaning that's called for (in fact, it links back to accuracy and precision).... hrm.

[edit] Mathematics section
I think 'Mathematics' is a poor name for the section heading. Perhaps 'Implementation' would be better? Also, I find the Javascript implementation at the end of the section inappropriate. It is basically the formula rewritten in code; supposedly Javascript code, but it is indistinguishable from 'pseudocode'. The <canvas> tag mentioned has no link or explanation, and isn't explicitly used in the code. --GrimRC 86.4.53.107 21:58, 6 July 2006 (UTC)
[edit] W-buffering merge
There is very little information at W-buffering, and there is not much hope for expansion as it is a very simple extension of Z-buffering. It should be merged here. - Rainwarrior 18:33, 14 August 2006 (UTC)
Most of the W-buffering is already in this article. Merging would probably be best. AdShea 13:35, 28 August 2006 (UTC)
- Done. - Rainwarrior 17:44, 28 August 2006 (UTC)
[edit] vertex / fragment shaders don't solve the Z-fighting problem
In the article it is claimed, that with vertex or fragment shader no Z-fighting would appear and clip planes were obsolete. This is definitely wrong. At best a fragment shader can change the z value, but the depth test is still performed and suffers from aliasing for similair numbers i.e. Z-fighting. For this reason I removed that part from the article. —The preceding unsigned comment was added by 88.217.40.168 (talk) 02:59, 30 December 2006 (UTC).
