<html><div style='background-color:'><P>Hi all,</P>
<P>I am using Marching Cubes to extract skin from visible human data and using the polydata as an input to fem program. The number of points for 10 slices is over 50000 points and 75000 polygons.I want to reduce these number of points as well as the number of polygons. I used vtkDecimate and vtkCleanPolyData. That didn't seem to help much, because it does not reduce the data after some point. Is there any way to control number of points generated by marching cubes or is there any way to decimate the number of points as much as we want?</P>
<P>my pipeline goes somewhat like this:</P>
<P>vtkImageReader=>vtkMarchingCubes=>vtkCleanPolyData=>vtkDecimate=>vtkPolyDataMapper=>vtkActor... </P>
<P>Any help greatly appreciated!</P>
<P>thanks</P>
