Hi Kevin,<br>I haven't used this particular function before, but it seems that you have not defined an axis of rotation for the Rotate3D command. <br><br>> transform->Rotate3D( -angle, false );<br><br>Needs to be something like<br>
<br>const itk::Vector<double, 3> rotationAxis;<br>rotationAxis[0] = 0;<br>rotationAxis[1] = 0;<br>rotationAxis[2] = 1;<br><br>transform->Rotate3D(rotationAxis,-angle, false );<br><br>I hope that helps.<br><br>Seth<br>
