I haven't found a solution to that problem in vtk. vtkDelauney2D will generate similar results. My current workaround is to extract vtkPoints from my actor, feed them into the Triangle library (<a href="http://www.cs.cmu.edu/~quake/triangle.html">http://www.cs.cmu.edu/~quake/triangle.html</a>) and put the resulting triangulation back in a vtkPolyData. Triangle does a very nice job and allows you to specify the maximum angle you want in your triangle as well as the maximum triangle area.<br>

Hi,<br>
<br>
How can I generate more or less equilateral triangles from a series of<br>
points that define the perimeter of a closed loop (e.g., an oval)? When I<br>
use vtkTriangleFilter the resulting triangles have poor aspect ratios (they<br>
have vertices on the perimeter of the oval and therefore are quite<br>
stretched). Can somebody suggest an approach where the triangles generated<br>
would be closer to equilateral? Adding points to the centre would seem to<br>
be necessary, but I was hoping there might be a filter that could do this<br>
without manually adding points.<br>
<br>
Thanks,<br>
<br>
Steve<br>
