different angles and altitudes. 3d plane can be rotated<br />
with mouse in my application. </p>
<p>Problem is this: I would like to rotate the plane so<br />
that I can view the plane directly from above it, but<br />
that seems to be impossible. The &quot;camera&quot; does not<br />
rotate around the plane when I increase the alt<br />
parameter [e.g. in call to plmesh()], instead the<br />
&quot;camera&quot; just moves linearly up and down and stays on<br />
the side of the plane. </p>
<p>I this the it is supposed to be? Or am I doing<br />
something wrong?</p>
<p>I would like to add that if this is the way the camera<br />
is supposed to move, the documentation is a little bit<br />
misleading because the documention says:<br />
&quot;The altitude should be restricted to the range zero to<br />
ninety degrees for proper operation, and represents the<br />
viewing angle above the xy plane.&quot;<br />
If alt parameter really represents the viewing _angle_,<br />
the camera should be directly on top of the plane when<br />
alt=90.</p></div>Otto NojonenWed, 10 Dec 2003 10:42:46 -0000http://sourceforge.netb9a655225ef1ca4fc8c15e1fbf1a6fa8fcef93ca
