Please add a diagram and some examples to make this more clear.

It looks like the diagram (provided by User:Jbergquist - thanks!) is pretty explanatory. If it is not adequate, say so. Otherwise, I'll remove the above image request. The Rod 17:01, 20 December 2005 (UTC)

[edit] context tag

Also, is the article still unclear or is it ready to have its context tag removed? The Rod 17:14, 20 December 2005 (UTC)

[edit] Link to Euclidean geometry?

What do we mean by parallel? The idea dates back at least to Euclid. If lines are translated without rotation they will remain parallel. This is a common drafting method.

[edit] Can this be right?

My intuition has failed me, but ... isn't the following assertion from the article plain wrong? Surely all the projections described here must project spheres into circles.

    In a general oblique projection, spheres of the space are projected as ellipses on the drawing plane, and not as circles as you would expect them from an orthogonal projection.


[edit] Query withdrawn

Sorry - the above query was b*ll*cks. Lucky nobody's paying attention anyway.

[edit] Image

I think this image is misleading, as the a and b from x+az and y+bz somehow are completely missing. Anyone has a better one? --Allefant 15:17, 19 June 2007 (UTC)

I replaced it now with another one. --Allefant 12:04, 20 August 2007 (UTC)

[edit] skew projection

Not a single google result besides Wikipedia says that skew projection is another name for oblique projection - so I'm removing it for now. If there's a book or paper saying so, it should be added in, citing the reference. --Allefant 13:21, 20 August 2007 (UTC)

[edit] less pretention

"Inferior to unity"? Come on, write "less than 1" like normal people. —Preceding unsigned comment added by 160.39.211.175 (talk) 16:35, 25 February 2008 (UTC)
