<DIV><FONT face=Arial size=2>Does anybody know exactly how works
quadricClustering ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I use it to decimate an (x,y,height) surface.
(ie I set a division</FONT></DIV>
<DIV><FONT face=Arial size=2>system where all the scene is in the same Z
division)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is it a simple decimation/interpolation of points
on a 3D grid </FONT></DIV>
<DIV><FONT face=Arial size=2>of X,Y and </FONT><FONT face=Arial size=2>Z
</FONT><FONT face=Arial size=2>sections ? What do the quadrics have to do
</FONT></DIV>
<DIV><FONT face=Arial size=2>with this </FONT><FONT face=Arial size=2>in my case
?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>and how triangulation is achieved once the points
are </FONT></DIV>
<DIV><FONT face=Arial size=2>decimated ? Is it a simple triangulation of each
square in my </FONT></DIV>
<DIV><FONT face=Arial size=2>case ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks</FONT></DIV>
