Error in Fig. 2

Sry, if my entry here doesn't comply with the Wiki-Standard, but in fig. 2 i think there is a mistake in the tabel @ p8: it says: "p5, p6, p7, p8". How can a vertex refer to itself? I think correct would be: "p4, p5, p6, p7".

You are correct, I replicated the image with the change and with the one in the last discussion entry. I reuploaded it on commons.

It seems there's an error in Figure 4. I think that the Vertex list has the coordinates for v8 and v9 transposed. i.e. v8 should have coordinates (0.5, 0.5, 1) and v9 should be (0.5, 0.5, 0). It this correct? Scoobadood (talk) 13:07, 25 April 2022 (UTC)

Diagram Standards

The images and tables in this article do not appear to be up to Wikipedia standards.

Deletion of a single invalid sentence

Under the first section entitled "Elements of Mesh Modeling", in the third paragraph, I deleted what used to be the third sentence stating "Figure 1 is a simplified cylinder, with 4 sides." because I could not find any illustration labeled as Figure 1, nor could I find an illustration of a simplified cylinder "with 4 sides". If the original author of this sentence would like to add a figure of a cylinder, I welcome it, especially since I believe all the figures in this article are excellent, very relevant, and very helpful!

Explanation of the WikiProject Computing Template I Added

First of all, the autobot placed this article within the scope of WikiProject Computing, which I agree with. Thus, I used the WikiProject Computing template. Note that the autobot left all other categories unfilled.

I rated the article as being Start-Class ONLY because it had three references; from http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Computing/Assessment, under the description for Start-Class articles, the rating of Start-Class should be applied for "An article that is developing, but which is quite incomplete and, most notably, lacks adequate reliable sources". The article seems to excel this description except in "adequate reliable sources", where three sources is considered inadequate for articles under the Computing WikiProject (i.e. articles with three sources are classed as Start-Class). Since I believe this article has much potential and is already quite informative, I will definitely raise my rating or agree with any other higher rating in quality when further sources are added.

Polygon meshes are very low-level and highly mathematical; they form a basis of computer graphics. Thus, I rated the importance of the article as "high". Considering the importance of polygon meshes in computer graphics, I believe the importance of this article can even be "top" if more low-level and mathematical information is provided.

I added the article to the computing portal because it definitely seems fitting.

This article is technically lacking an infobox, so I noted that.

This article falls under the category of computer science, and for the same reasons as noted above, I believe it is of high importance and potentially of top importance once lower-level information is provided.

I am interested in this article, in particular, because of its potential. With a few relatively minor changes, I believe this article can scale Wikipedia's importance and quality scale. I also want to complement the author or authors on the tables and figures already in the article; I will take a look at the diagram standards, since I am not familiar with them myself. I hope the original author or authors do not mind if I add a few things. Some Old Man (talk) 10:48, 6 May 2009 (UTC)

On the Addition of {{Refimprove|article|{{subst:DATE}}|talk=y}} to the Article Edit Page

Since I believe this article excells its rating in all categories except for the number of references it has, I added a request for references for verification to the article page. Following the addition of more references, I believe the article's rating should be higher.

I think excel is a frame of mind, but I agree with you that it is by and large correct and just does not have references. The problem: who wants to just add references to a correct article? That is the Wikipedia Paradox. If this article had been really low quality, I would have probably fixed it and added references in the process. But now... there are other things to do, so this will have to wait. In the meantime, are you also relying on my rationale not to add references here, just because it has so few errors?

Error in diagram for face-vertex meshes

I do not know how to fix these diagrams! — Preceding unsigned comment added by Ravenspoint (talk • contribs) 16:21, 10 June 2011 (UTC)

The figure 2 (vertex-vertex meshes) is ok. But the list of corrections bellow need to be made in figure 3 (Face-vertex meshes): Face List - f12 list is wrong, should be: v9, v1, v0 - f13 list is wrong, should be: v9, v2, v1 - f14 list is wrong, should be: v9, v3, v2 - f15 list is wrong, should be: v9, v0, v3

Vertex List - z component of v8 vertex is wrong, should be (0.5, 0.5, 1) instead of (0.5, 0.5, 0). - z component of v9 vertex is wrong, should be (0.5, 0.5, 0) instead of (0.5, 0.5, 1). - v9 list is wrong, should be: f12, f13, f14, f15

The article low poly has been nominated for deletion.

Face List Table Error

I’m afraid the vertices for f12, f13, f14 and f15 in the Face List table are incorrect. They should be {v0, v1, v9}, {v1, v2, v9}, {v2, v3, v9} and {v0, v3, v9}, respectively. Can someone please verify and make the necessary corrections?

You are right in my opinion. But your brand new faces are wrong, the last one should be {3,0,9} because of face lining. — Preceding unsigned comment added by 212.91.166.163 (talk) 14:11, 24 August 2015 (UTC)

Mistake in "elements" example image

"polygons" and "faces" need to be swapped, they each refer to the other imaged example. — Preceding unsigned comment added by 2600:6C54:4400:C76:8C4D:5D82:5390:F811 (talk) 05:26, 3 September 2019 (UTC)

Please add math formalization
