<font face="Myriad Pro">Cher Manuel,<br>
<br>
pouvez-vous donner un example concernant l'option VIEWPOINT de
pst-solides3d, que le point de vue va à une ligne de constant
radius (r) de (0/0/0) du pole nord vers le pole sud (avec
multido).<br>
<br>
Ma méthode est:<br>
<br>
</font><b><font class="Apple-style-span" color="#3333ff">\psset{viewpoint=70
40 \r\space </font></b>rtp2xyz<b><font class="Apple-style-span"
color="#3333ff">,Decran=50,lightsrc=50 40 35}</font></b><font
face="Myriad Pro"><br>
de l'exemple:<br>

<font face="Myriad Pro"><br>
C'est que Pedro voulait savoir... La rotation sur l'axe z n'est
pas un problème...<br>
<br>
Avez-vous quelque chose comme ca dans votre archive? Si oui --
permettez-le à Pedro -- il veut être hereux.<br>
<br>
J'ai lit les mots concernant le malheur de JPV -- my thoughts are
with him. Il me manque plus de mots.<br>
<br>
A bientôt,<br>
<br>
Juergen<br>

Do you use PStricks?(I think the answer is positive)<br>
