<p class="MsoNormal"><span lang="EN-US">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I’m working on a text projector which is able to project an arbitrary text on a surface mesh (polydata).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">To do so, I create two sets of points one on the original text landmarks and one on the surface corresponding landmarks.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I then transform the text with vtkThinPlateTransform using these two datasets.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">It works very well but it’s not as optimal as it could be.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">One word of seven letters, for example, is composed of about 760 3D points.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">When I apply the transformation on it, it takes about 35 seconds to complete the computation.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I googled about an optimized TPS for vtk and didn’t find any relevant response, despite the mail from the list inquiring about the same topic but dating back to 2004 and which didn’t receive any relevant answer...
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Therefore, does anyone use a faster, functional TPS version I could try in order to reduce this computation time ?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks in advance,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Best regards,<o:p></o:p></span></p>
