<div>Dear Ken,</div>
<div> </div>
<div>that's perfect, thank you very much! I wasn't aware of fields and never used the calculator before.</div>
<div> </div>
<div>For those who are interested, this is how my wireframe looks now:</div>

<div>Wireframes in ParaView are colored the same way as most of the other representations (like surface, points, or volume). In all cases in order to color by something other than a solid color, you need a field defined over the mesh.</div>
</div>
</div>
<div> </div>
<div>It sounds you want to color based on the physical location. You can create a field like that easily with the Calculator filter. Just make the expression of the Calculator "coords" (which is a special vector representing the point coordinates). Here is a screen shot of creating a coloring similar to your example of the disk_out_ref dataset using just the ParaView GUI.</div>

<div><span id="OLK_SRC_BODY_SECTION">Dear all,</span></div>
<div><span id="OLK_SRC_BODY_SECTION"> </span></div>
<div><span id="OLK_SRC_BODY_SECTION">I wondered if it is possible to color a wireframe with a a color gradient (or random colors)</span></div>
<div><span id="OLK_SRC_BODY_SECTION">instead of a solid color. I have a 3D mesh exported from GMSH, with a lot of interior points/edges.</span></div>
<div><span id="OLK_SRC_BODY_SECTION">I use a shrink filter in Paraview to thow the interior edges, but since the are all colored homogenously</span></div>
<div><span id="OLK_SRC_BODY_SECTION">it is impossible to distinguish any features.</span></div>
<div><span id="OLK_SRC_BODY_SECTION">Here's a Screenshot:</span></div>

<div><span id="OLK_SRC_BODY_SECTION"> </span></div>
<div><span id="OLK_SRC_BODY_SECTION">I would like to have the mesh shown at least a little bit more like in GMSH:</span></div>

<div><span id="OLK_SRC_BODY_SECTION"> </span></div>
<div><span id="OLK_SRC_BODY_SECTION">In best case, the coloring of the edges would be depending on the X-,Y-,and Z-location.</span></div>
<div><span id="OLK_SRC_BODY_SECTION">I found this screenshot featuring different edge colors, but the model is created from</span></div>
<div><span id="OLK_SRC_BODY_SECTION">Python and visualized in an OpenGL window instead of Paraview.</span></div>

<div><span id="OLK_SRC_BODY_SECTION">The idea seems to be to set the 'ColorAttributeType' to 'POINT_DATA', but this doesn't help me much.</span></div>
<div><span id="OLK_SRC_BODY_SECTION"> </span></div>
<div><span id="OLK_SRC_BODY_SECTION">Could anyone hint me to a solution of how to achieve a multi-colored wireframe in Paraview?</span></div>
