3d projection

Hello, I placed the welcome template from Wikipedia:Standard user greeting above since your talk page looked so empty, but why I'm actually writing is the 3D projection article - I was wondering if you consider it ready for inclusion into article space now? I think it's a lot better than the current article - of course there's still many things which could be added, any maybe some things which could be kept from the current one, but that can happen once it's moved from the talk page.

Oh, and seeing how many articles are criticized lately for incomplete sources - do you have page numbers (assuming it's all from that one book) for the info in each of the sections? --Allefant 10:27, 21 August 2007 (UTC)[reply]

I have moved Stestagg/3D to User:Stestagg/3D in accordance with naming and namespace convetions. -- RHaworth 12:30, 11 September 2007 (UTC)[reply]

The new 3D projection page is wrong!!! You have removed the projection and other matrices that are the most important thing about projections. Rotations and translations have nothing to do with projecting and therefore if you want to remove anything or rewrite it, remove those! I'm undoing it again to previous version. Previous article was better, because if you read it through and had enough mathematical knowledge you actually understood how OpenGL works (because the final projection described there is the one from OpenGL). So, add the projection matrices for al the projections and remove simplified non-matrix bullshit (sorry for language, but I'm angry)! —Preceding unsigned comment added by 86.61.2.122 (talk) 15:55, 23 September 2007 (UTC)[reply]

To clarify, the new 3D Projection page is correct, I replaced a page that looked like it had been copy-pasted from an OpenGL documentation, with one that introduces generic 3d Projection from a mathematical viewpoint. Thus anyone creating a projection routine, or trying to project, can look up the formulae and get it done. If you want an OpenGL tutorial, visit wikibooks.

We should probably merge useful info from the previous one. The previous article seemed to just describe one specific way (OpenGL?) of displaying a 3D scene, and it only had one single reference (besides the one I added later). The current version indeed leaves out many things which still could be said, and we also never got around to clean things up with respect to other articles with overlapping info (Graphical projection, Perspective projection, and so on..). But the current one can count as a concise encyclopedic description of 3D projection, so I think it is a much better base to work from. --Allefant 09:30, 24 September 2007 (UTC)[reply]
