[vtkusers] 2D/3D Visualization

[Lasso, Andras (GE Healthcare)]

Hi,

Probably the easiest way is to create a 2D image from your 3D shaded model by off-screen rendering (vtkWindowToImageFilter) then fuse it with the original 2D bitmap (vtkImageBlend) and display with a 2D image viewer (vtkImageViewer2).

Hi all,

  i need to know if i could visualize a 2D bitmap (photo) and a 3D shaded model of the object by using the Vtk toolkit.

The intention is not to do texture mapping but a 2D/3D superimposition of the coincident regions. Obviously, transparency is needed for properly visualizing, besides transforming the 3D model to achieve accurate superimposition results. For instance, think about the superimposition of the photo and the 3D model both of a given person's face.

Thanks in advance.
