[edit] What belongs here?
Strictly speaking, CGI is the film technique. The beauty pageant is confusing because it is for video game characters, and the intro specifically mentions that CGI doesn't usually refer to video game characters. The part about web commerce avatars is unrelated as well since that is a real-time computer graphics application. I removed these sections. – flamuraiTM 21:38, Jan 26, 2005 (UTC)
I think the distinction between CGI and Computer animation is slight. It can't really be called a film technique because of its major application, as listed here, to pure animation, and whether this is for film or video is only a matter of detail and the resolution used for rendering. HDTV is blurring the separation of 'film' and video, with movies about to be shot and delivered digitally, with no 'film' ever involved, not even Videotape. The resolution used for Toy Story was, surprisingly, lower than HDTV. If there is a distiction, CGI is probably just a matter of 'hi end' (3D Hi-Res) as opposes to 'lo end' (2D) animations --Lindosland 18:12, 29 December 2005 (UTC)
We must be careful to preserve the 'hierarchy', which is a problem arising in many Wikipedia pages. CGI is a class of computer animation, which is a form of animation. Games take the concept to real time, and Avatars perhaps even further. Some unnecessary repetition is occuring here. I have suggested the concept of 'Root pages' to get round this. I would call 'animation' the root page, and then list this first in the list of see also, on all associated pages. -Lindosland 18:18, 29 December 2005 (UTC)
- I do not totally agree on the hierarchy nature of CGI as a class of animation, I mean, CGI could be a class of many other things (e.g. it could be son of Computer Graphics, Visual Effects and so on...). The top of page backlink seems to me out of place. I would like to remove the top one and leave just the back link in the 'see also' section. ALoopingIcon 23:31, 27 February 2006 (UTC)
[edit] A good CGI weblog
Is there a good weblog that covers the latest developments in CGI, e.g. new movie releases, software, etc.?--Eloquence* 22:58, July 28, 2005 (UTC)
"The first real CGI character was created by Pixar for the film Young Sherlock Holmes in 1985 (not counting the simple polyhedron character Bit in Tron)."
Wasn't the MCP in tron also conputer animated? Or was that simply hand-drawn animation appearing to be computer animation? If so, it certainly counts even if Bit doesn't.
Also there is a movement to refer to CGI as CG instead, as CGI is more commonly (in technology) used to refer to Common Gateway Interface, the protocol to submit web forms.

[edit] This is mostly the history of CGI - need 'how its done'
This is mostly a history of CGI, but gives little clue as to how it's done. While I know something of this, I'd like to know how characters are moved realistically, how many variables are involved, is it done by entering numbers, or by dragging opbjects, or by people wearing lights that are tracked, as I've seen demonstrated? Can someone write a section headed, "how it's done"? The modelling page is mostly about rendering, and does not answer the question.--86.135.122.101 11:58, 29 December 2005 (UTC)
[edit] Hierarchy needed? - the 'Root page' suggestion
This is only one of many good articles on aspects of Animation, all of which tend to be suffering from omissions and duplications, as well as misconceptions over what constitutes CGI for example, as opposed to, computer animation, and whether CGI is a 'film technique'.
I've solved a similar dilemma on other topics by introducing the concept of a 'Root page', in this case Animation, and a hierarchy. I suggest that CGI is computer animation, is animation. If anything, CGI is 'hi-end' computer animation, meaning probably hi-res 3D rather than 2D, but the distinction is disappearing. CGI cannot be a 'film technique' as fully animatied 'movies' like Toy Story are now about to be delivered to cinemas digitally without ever seeing 'film' even as 'videotape'. Avatars and games come 'highest' in the hierarchy, as they involve real-time CGI.
The newcomer to CGI, or to Computer animation, may need to have animation explained, hence the need for hierarchy, with the 'Root page' listed at the top of 'see also' and described as such. The Root page should list all key associated pages in the hierarchy first. --Lindosland 18:35, 29 December 2005 (UTC)
[edit] Digital effects versus analoge effects
I was just wondering. Can a digital computer today do everything an analoge tool can, or can analoge effects still do some things better than digital? Like Lear Siegler Video Synthesizer and some of the other stuff they used in movies such as The Andromesa Strain (1971)? —The preceding unsigned comment was added by 193.217.136.92 (talk) 17 January 2006.
[edit] Vandalism
This page has been vandalised but for some reason I can not do a rollback like on the Afrikaans wikipedia. --Renier Maritz 13:46, 2 February 2006 (UTC)
[edit] CG
Computer-generated imagery is often referred to simply as CG (though this is a less specific term). The initialization CGI also has different meanings, which could be confusing. Maybe these should be mentioned here? WurdBendur 05:54, 18 March 2006 (UTC)
I concur! I hate the term CGI when referring to graphics.
[edit] Criticisms
Someone needs to address some peoples criticism of CGI. —The preceding unsigned comment was added by Metnever (talk • contribs) 16 April 2006.

- Yes, I agree (although I think the criticisms are silly). Scorpionman 01:14, 1 May 2006 (UTC)s
I'm actually getting pretty tired of seeing every main-stream animated movie in CGI. —The preceding unsigned comment was added by 68.96.200.103 (talk) 5 August 2006.
[edit] Motion graphics
Is Motion graphics a synonym of CGI? I thought a merge to this might be OK. thoughts? --Clubmarx 03:58, 19 June 2006 (UTC)
[edit] Free?
How is Maya free? --Chewxy
- I think whoever wrote that is thinking of Maya Personal Learning Edition. However, I think that the section in the article is a permanently incomplete list stuck in the middle of an otherwise useful article. I'm about to remove it in a minute or two. Ayavaron 21:02, 10 September 2006 (UTC)
[edit] Spoilers
I just turned to this article and had a movie — the second Pirates of the Caribbean — spoiled for me with the picture that some clever person put up. Thank you! Not everybody in the world sees every movie right away. Wouldn't it have been possible to show a picture from an older movie? —The preceding unsigned comment was added by 24.182.34.229 (talk) 19 September 2006.
