<br>I used vtkPolygon::PointInPolygon before, it is not bad.<br><br><div class="gmail_quote">On Thu, Mar 25, 2010 at 8:22 AM, superzz <span dir="ltr"><<a href="mailto:jxdw_zlf@yahoo.com.cn">jxdw_zlf@yahoo.com.cn</a>></span> wrote:<br>

Hello<br>
<br>
Given a polydata, is there a quick way to get all points with integer x,y,z<br>
coordinate inside it? I know empolying vtkOBBTree with the following code<br>
can do this. But it runs toooooo slow.<br>
<br>
for (int x = 0 ; x < maxX; ++ x){<br>
for (int y = 0 ; y < maxY; ++ y){<br>
for (int z = 0 ; z < maxZ; ++ z){<br>
obbTree.InsideOrOutside(new double[] { x, y, z });<br>
}<br>
}<br>
}<br>
<br>
Thanks<br>
<br>
