note that a page needs creating on Oblique Projection and added as a link after "oblique Projection" on this page. Pat 23:17, 20 Feb 2004 (UTC)

[edit] Problem with nested links

Isn't Axonometric projection a sub-category under Orthographic projection? If so, it should be properly nested.67.170.168.214 06:43, 17 October 2006 (UTC)

[edit] Planometric Projection

What about listing planometric projection on this page? Where,

\begin{bmatrix} x' \\ y' \\ z' \\ 1 \end{bmatrix} = \begin{bmatrix} \cos \frac {\pi}{4} & - \cos \frac {\pi}{4} & 0 & 0 \\ \sin \frac {\pi}{4} & - \sin \frac {\pi}{4} & 1 & 0 \\ 0 & 0 & 0 & 0 \\ 0 & 0 & 0 & 1 \end{bmatrix} \begin{bmatrix} x \\ y \\ z \\ 1 \end{bmatrix}

Got a reference for that? It looks like a kind of Oblique projection to me, in fact it's this one I think: --Allefant 09:19, 4 September 2007 (UTC)
Yes. That's it. But it's not the same as oblique. But I don't have any references, and I don't know how widely used it is. Yet I still learn it at school so I thought it should be included. Can't you use wherever you got that image as a reference? Me121121 09:42, 6 September 2007 (UTC)
So the fact that each 3d dimention is distorted equally (45 degree) means that accurate scale drawings can be made, because a 3d line of length x will always be projected as a 2d line of length cx, irrespective of the line's orientation. This feature makes Planometric images look ugly as sin, but also makes the projection notable. —Preceding unsigned comment added by Stestagg (talk • contribs) 14:26, 14 May 2008 (UTC)
