There reads: This is a list of some of the most common test 3D models
Some of these probably are not "most common" models, such as VW Beetle. Maybe this should be renamed as 'List of notable 3D test models'. 85.217.42.90 (talk) 18:26, 8 July 2013 (UTC)

It's redundant to put the word "Notable" in there because Wikipedia requires all information in articles to be notable. The Beetle was certainly common at one time - although it's rarely seen these days. I believe it's important to keep information about the historically popular models.

There are lot of info in Wikipedia that is not notable on its own. This list also has four entries which do not have an article. Also, is it sure all notable models were common? Of course, if you only had one place back then to use them, then all of them were common. 85.217.42.90 (talk) 17:53, 19 July 2013 (UTC)

Roman/Greek bust?

I've seen a model used in some shader demos that is a man's head with beard and long curly head. He's wearing a helmet. It looks Greek or Roman. It seems like it should be made of marble. Any one know what it's called? --209.203.125.162 (talk) 01:35, 24 January 2014 (UTC)

Luxo?

This list shouldn't include Luxo from Pixar, it was developed precisely to demonstrate what Pixar could do with their technologies at the time. --189.212.206.164 (talk) 13:02, 25 March 2014 (UTC)

"Commonly used" means "used by different researchers and/or companies". Things like the Utah Teapot have been used by lots of people, unrelated to the original person and institution which created it. That's the point of this list - models which have transcended their origin, to become part of the general discourse of computer graphics. As far as I know, Luxo Jr. is Pixar's propretary thing, and only they have have used it. For it to merit inclusion here, we'd need recent references showing other people, unrelated to Pixar, have used that model in other circumstances, unrelated to the Luxo Jr. film. -- Finlay McWalter··–·Talk 22:36, 30 October 2019 (UTC)

Data discrepency in the entry for "Suzanne"

As of this posting, the "Inspiration (if any)" column says the Suzanne model is an orangutan, while the "Comments" column says the model is a chimpanzee. At least one of those has to be incorrect... Does anyone have a source saying what Suzanne is a model of?

I believe this is where I took the information from: Blender (software)#Suzanne —Kri (talk) 19:29, 27 June 2015 (UTC)

How common does a 3D test model have to be for inclusion in this list?

Especially in relation to time/use-range? The Sutherland Team's Volkswagon used to be very common, but currently isn't (and has now been removed); 3DBenchy is very common for testing 3D printers, but rare for other 3D uses. I personally remember several instances of the Stanford Lucy and Stanford Dragon being used for testing software, hardware, etc, but the Stanford Lucy has recently been removed. I have pdfs of some old papers that used the Max Planck model, but how many citations are needed to establish previously common usage? KickAir 8P~ (talk) 21:55, 1 November 2020 (UTC)

I imagine the Volkswagon was a common model used because of the resources required to create it (a whole team of students) and the lack of alternatives. I think it should probably be back on the list, but there was no information about it being used as a test model, just like the hand Catmull created. I removed some of the Stanford models because it looked like someone just went through the link for the model repository and added the models without care for how frequently they were used. There was no information about the Planck model (no cite, no image, no article) so it was also removed. UserTwoSix (talk) 22:45, 1 November 2020 (UTC)

You can see in 2013 it was brought up that the VW model was "notable" but maybe not "common", just like Catmull's hand. You can also see that it would be nice to include Luxo Jr. on the list (per talk discussion), but the article title would have to be changed. Do you have any ideas for a new article name that would include these models? However, we don't want to list every single model (e.g. in the Stanford repository). UserTwoSix (talk) 23:16, 1 November 2020 (UTC)

There's info here on how to establish an instance's notability & verifiability for Wikipedia's purposes, and how to cite that. But if there's anything on how to show that something is/was common (and therefor belongs on a page listing common whatevers) I'm not finding it. I know that the The Sutherland Team's Volkswagon was a common 3D test object, reasonably available to early 3D researchers to try on their own equipment, while Catmull's Hand wasn't distributed outside of analog images, but third+ hand forum anecdotes meet neither verifiability nor citation standards even when the forums still exist. And that's for individual instances -- what does it take to establish that something's use is/was common? It's not like people were saying in their papers "I used this common 3D test object", they weren't thinking in those terms. >

Which brings up the next bit: where/when does a 3D test object need to be "common" for inclusion on this page? The Sutherland Team's VW is still in use, but not often compared to the early days of 3D; 3DBenchy is currently very common when testing a 3D printer, rarely used outside of that; Suzanne's very common among Blender (a popular 3D program) users, rare in other 3D communities. If it can be argued that Luxo is a common 3D test object at Pixar is that enough? If The Other Nefertiti became a common 3D test object via Streisand Effect rather than through any suitability for the role, does that disqualify it? >

It seems like things are being added to and removed from this list according to personal recollections rather than any established standard -- what's Wikipedia's standard for establishing commonality? Is there one? Because if there is I haven't found it. KickAir 8P~ (talk) 21:27, 2 November 2020 (UTC)
