<DIV>Hi Luis, </DIV>
<DIV> </DIV>
<DIV>I followed your advice and tried to create my own class to display my image with VTK. </DIV>
<DIV> </DIV>
<DIV>However, as Ì'm still new to VTK, I'm not familiar with all this notions of camera, actor, mapper and so on. I tried to set up my own parameters of a camera. However, I succed to view only a part of my image 1552*128.</DIV>
<DIV> </DIV>
<DIV>Here is what I did: </DIV>
<DIV> </DIV>
<DIV> <STRONG> m_Camera = vtkCamera::New();<BR> m_Actor = vtkImageActor::New();<BR> m_Renderer = vtkRenderer::New();<BR> m_RenderWindow = vtkRenderWindow::New();</STRONG></DIV>
<DIV><STRONG></STRONG> </DIV>
<DIV><STRONG> //setup the pipeline<BR> m_Renderer->AddActor( m_Actor );<BR> m_RenderWindow->AddRenderer( m_Renderer ); </STRONG></DIV>
<DIV><STRONG> </STRONG></DIV>
<DIV><STRONG> // The usual rendering stuff<BR> m_Camera->ComputeViewPlaneNormal();<BR> m_Camera->SetViewUp (0, 0, -1);<BR> m_Camera->SetPosition(0,0,1);<BR> m_Camera->SetFocalPoint(0,0,0);<BR> m_Camera->ParallelProjectionOn(); </STRONG></DIV>
<DIV><STRONG></STRONG> </DIV>
<DIV><STRONG> m_Renderer->SetActiveCamera(m_Camera);<BR> m_Renderer->ResetCamera();<BR> m_Renderer->SetBackground(0,0,0); //set a background color </STRONG></DIV>
<DIV><STRONG></STRONG> </DIV>
<DIV><STRONG> m_Actor->SetInput( image)<BR> m_Camera->SetClippingRange( 0.1, 1000.);<BR> m_RenderWindow->Render();</STRONG></DIV>
<DIV> </DIV>
<DIV>Do you think one or several parameters are not correct and explain my result, If so, could you tell me which one.</DIV>
<DIV> </DIV>
