[vtkusers] forward projection, vtkDividingCubes and vtkGaussianSplatter problems

[Zeger Knops]

Hi,

I'm writing example programs for students so they can get the feeling of the algorithms they have to learn for the exam. But when I tried to create an example for splatting I gut stuck, same thing for the forward and back to front example and also for the vtkDividingCubes (which as in the orginal algorithm should stop dividing when the subvoxel size is pixel size).
Any solutions?

  Hello Zeger,

  What are you trying to do? If you are trying to render a volume, you can use vtkVolumeRayCastMapper or vtkVolumeTextureMapper2D. Or, if you have a VolumePro board from RTViz, you can use the vtkVolumeProMapper. The vtkGaussianSplatter is not an implementation of splatting for volume rendering.

    Hi all,
     
    - Is there any way in vtk to do back-to-front or forward projection?
    - Is there any way to implement vtkDividingCubes so that the divisions will stop when the subdivision is pixel size?
    - vtkGaussianSplatter doesn't seem to do what it is supposed to do, because it splats in 3D, in the orignal algorithm a plane moves back to front through the volume and every voxel leaves a "footprint" on the plane, this doesn't seem to happen with vtkGaussianSplatter (or am I wrong?), is there a way to do this right?
