Recent changes to 91: plw3d distortion as alt -> 90 degreeshttps://sourceforge.net/p/plplot/bugs/91/2010-05-25T16:28:38Zplw3d distortion as alt -> 90 degrees2010-05-25T16:28:38Z2010-05-25T16:28:38ZAnonymoushttps://sourceforge.net/u/userid-None/https://sourceforge.netf770396d3cd71069ae0b6fbce8487238e615e97a<div class="markdown_content"><p>plw3d with the altitude set to 90 degrees and different azimuths produces non-rectangular projections. For azimuths 0, 90, 180, etc. the result is a rectangle corresponding to the xy plane. But for other azimuths this projection is a parallelogram. See the attached plots which are from x08 but with the alt set to 90. I<br />
would expect this to always give a rectangle regardless of the azimuth.</p>
<p>Notice also that the axis labels are not correct; those should degenerate into a straight line at alt 90.</p></div>
