Hello <br><br>i am using the following code in C++... just for clarification i am storing the coordinates of the points in std::vectors... i also use a custom class for 3D points (Pt3D)....<br><br> vtkTransform transform;<br> transform.Identity();<br> transform.PostMultiply();<br> transform.RotateWXYZ(45, X, Y, Z); //X,Y, Z are the coordinates of the normal of the plane i rotate<br> transform.Translate((Origin[0] + Spacing[0]*100),(Origin[1] + Spacing[1]*200),(Origin[2] + Spacing[2]*100));<br><br>double* p;<br>p = transform.TransformDoubleVector(vtkLandmarksBuffer[i].getAll() ); //getAll() returns an array with the coordinates of the point<br>Pt3D Point3D(p); //Pt3D is a custom class for 3D Points (x,y,z)<br>landmarksBuffer.push_back(Point3D);<br><br>delete p;<br><br>the points with the new coordinates are stored in the landmarksBuffer vector. However when i
visualize the result i only see the rotation part of the trasnform<br>. In fact when i put the rotation in comments then i see no difference in the new points. So for some reason the translation doesn't work at all. Do you know if TransformDoubleVector() method has any kind of problems like that? I know that i should probably choose the polyDataFilter approach but i thought this way could be easier for me...<br><br>Any insight is welcome<br><br>Thanks <br><p>
