Then in ParaView, load the data set and then apply a "Glyph" filter which puts a sphere at each point. Then color the spheres by the scalar value attached to each point. <DIV> _How_ you load the data into paraview is left as an exercise to the reader. Hint - If your data is NOT already in a format that ParaView understands then writing a legacy VTK file is the easiest route to get your data into ParaView. </DIV><DIV><BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Bitstream Vera Sans; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">-- </DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Mike Jackson Senior Research Engineer</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Innovative Management & Technology Services</DIV><BR class="Apple-interchange-newline"></SPAN> </DIV><BR><DIV><DIV>On Sep 17, 2007, at 7:38 PM, Patrick Birch wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"> Hi experts,<BR><BR>I need to visualize a random scattering of points (unstructured), and then colour code them according to their associated scalar values.<BR><BR>It seems that the only way to visualize unstructured points is to somehow create a surface out of them, whether by delaunay triangulation or splatting.<BR><BR>Is there a way to just view the points as is? <BR><BR>Thank-you kindly and best regards<BR><BR>PB<BR><BR><HR>Can you find the hidden words?
