<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m new to VTK and I am trying to use it so that I can create a colour map on an object to represent some measured data with some interpolation. In real life I have an object with sensors in various locations. I have a 3D model of the object
which I have imported into vtk as an STL file. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I now want to assign the measured data to the relevant locations on the model, then I want to interpolate between the measured data points so every vertex has a value. I then want to have a colour scale dependent on the value of the vertex.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m not sure how to go about this or if it’s possible. My specific queries are:-<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ol style="margin-top:0cm" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1">Can I click on the model for it to give me the location of the nearest vertex to my mouse click? If so, how can I?<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1">What is the best way to interpolate between the known measurements? I don’t need each value across the mesh, only the final colours – would it be better to assign colours to the known
points and then interpolate colour between them without doing the numbers?<o:p></o:p></li></ol>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Many thanks,<o:p></o:p></p>
