Thanks for you responses!
What I have to display is a 3d path of some measurement points.
These have (a bit simplified) to lie inside different spheric thresholds that are displayed together with other properties.
The goal was to mimic existing 2d plots (projections) which somehow restricts how it should look like.
I do like the idea to use wireframes, I'll see if that can be close enough to what I need.
Greetings,
Matthias

<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></p>
