I have the same problem that Karima has,<br><br>I tried Jeff's solution but it does not work.<br>so I decided to tried a vtkColorTransferFunction, but it does not work either...<br>any other ideas.?<br><br><br><br><br>
<p>vtkColorTransferFunction * pColorTransferFunction =
vtkColorTransferFunction::New(); for (int i = 0; i < m_iNumberOfColors;
</p><div class="footer noise"><p>
</p></div><p>i++) {
pColorTransferFunction->AddRGBPoint(value[i], red[i], green[i],
blue[i]);
}
// pColorTransferFunction->SetAlpha(0.1) does not work also!!
</p><p>vtkPolyDataMapper * pPolyDataMapper = vtkPolyDataMapper::New();
pPolyDataMapper->SetInput(pPolyData);
pPolyDataMapper->SetLookupTable(pColorTransferFunction);
</p><br><br>Karima,<br>

</div>Do you mean color? Texture coordinates (i,j) should be assigned using<br>
SetTCoords.<br>
<br>
I assume instead you have RGB (0-255) colors for each point. These can<br>
be assigned to a 3-component vtkUnsignedCharArray and added to the<br>
PointData. Name the array, and call<br>
<br>
mapper->SetColorModeToDefault(<div id=":143" class="ii gt">);<br>
mapper->SetScalarModeToUsePointFieldData();<br>
mapper->SelectColorArray(name);</div><br><br><br><br><div class="gmail_quote">On Mon, Mar 30, 2009 at 9:30 AM, Jeff Baumes <span dir="ltr"><<a href="mailto:jeff.baumes@kitware.com">jeff.baumes@kitware.com</a>></span> wrote:<br>
