color=#0000ff size=2>Thanks for your help. In fact, I'm not directly associated
with this problem. I've posted the message for a friend of mine, a non
Paraview/VTK user, just to help him. He works with DEM (Discrete Element Method)
and is looking for a visualization technique able to build a surface
representation from his point data. </FONT></SPAN><SPAN
class=890323500-16022006><FONT face=Arial color=#0000ff size=2>After
"Googling" for a while, we've found information pointing to splatting
method used to represent 3D scanner data. It seems that this rendering
method is also used by SPH (Smoothed Particle Hydrodinamics)
researchers to visualize their results. Therefore we've thought about
posting a message on the Paraview list. Anyway, I'm grateful for your help
and I'll forward this message to my friend in order to place him in contact with
you (or others PV folks). Are you ok about it ?!</FONT></SPAN></DIV>

<DIV></DIV>Renato,<BR><BR>Hi. I'm just starting to use this thing (Paraview),
(actually on something like my 9th hour of using it), so take what I say with a
grain of salt.<BR><BR>I'm working with a dataset structured as the following:
<BR><BR>29 11 99
99 93 94<BR>14
12 71 99 94
94<BR>13 10 14
39 38 39<BR>08
10 32 39
38 39<BR><BR>Where the first three pairs are going to be my
x,y,z points, and the next three are my R,G,B values. <BR><BR>What I've done
is:<BR><BR>File>Open Data:<BR>Choose RAW... Under Files of type:<BR>Click OK
on the error dialog.<BR>Choose RAW in the next dialog.<BR><BR>OK. Now we've
brought your data in.<BR><BR>Now, set your "File Dimensionality," in my case 3.
<BR>Next, under Extent, set the min and max for each of x,y,z in the pairs of
boxes.<BR><BR>For the rgb values, in my case, I set the "Num. Components" value
to 3.<BR><BR>Now simply name your array ("Array name"). <BR><BR>Now, again
working from my example, click on the "Display" tab above.<BR><BR>Set "Color
by:" to your array.<BR><BR>You might also want to click on "Set View to Data" to
center your object. <BR><BR>Hope this helps.<BR><BR>Chris Larson<BR>Just this
guy.<BR><BR>PS If we're both just learning the interface, mebbe we can help each
other out. Feel free to ask me questions, understanding that I a noob in this
application. <BR><BR>
