<p style="margin-top:0;margin-bottom:0">Preserving the color of the original hidden faces under interactive rotations, does not seem to be a bad idea. It<span style="font-size: 12pt;"> allows assessing what parts of the objects are hidden under the original
choice of view angles.</span></p>
<p style="margin-top:0;margin-bottom:0">The behaviour of plot3d is similar.</p>

<p><font face="Arial">Using hist3d() -- just enter hist3d() to plot the example --, and rotating the figure in 3D (right-press and drag), we can note that the color of the different faces are not the same: 2 of the four faces are rendered with the hidden color
(usually used for the internal or back faces), and the 2 other ones with the default or chosen color and color mode.</font></p>

is a bug</a>.<br>
<br>
Now, i am wondering if it is not rather intentional, in order to have a kind of lighting effect.<br>
<br>
I still think that, even if it was intentional, it should rather be fixed. Now, Scilab has some explicit lighting features.<br>
<br>
But, before possibly processing the bug report, what's your opinion?<br>
