<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana","sans-serif"">Hallo!<br>
<br>
For a visualization I need to display several colored 3d spheres, that might overlap or even be included completely in each other. Included spheres should be visible all the time. My solution was to make the spheres transparent.<br>
Unfortunately that means, that colors are not preserved, a red sphere in a green sphere in a yellow sphere in a blue sphere ... not much of the original color left.<br>
Is there a way to achieve the (physically uncorrect) behaviour of preserving the colors?<br>
<br>
Thanks,<br>
Matthias</span><o:p></o:p></p>
