A Short description of the modules needed to integrate a CUDA based Volume Rendering into VTK
 
 
 
=== VTK Modules and Pipeline ===
 
These are the modules that will be created in order to integrate a Cuda based Volume Rendering into Slicer3
 
# '''A [http://www.vtk.org/doc/release/5.0/html/a01572.html vtkImageReader]:''' to read Volume data as any kind of Volume Data
 
# '''A [[vtkCudaImageFilter]]:''' A Filter to convert from the reader output to a cuda-able DataSet
 
# '''A [[vtkCudaDataSet]]:''' A new vtkDataSet where that holds and handles the data transfer from and to one or multiple CUDA devices.
 
# '''A [[vtkCudaVolumeMapper]]:''' A new vtkVolumeMapper that renders the scene using the
 
## lighting model
 
## a prepared Z buffer
 
## a camera position
 
## A [[http://www.vtk.org/doc/release/5.0/html/a02096.html vtkTexture]] and a Plane to render the result to
 
# '''An actor''' that places the volume into the scene
 
# Chain this '''pipeline''' together and attach it to a rendering window.
 
 
 
In the following image the pipeline is displayed together with the connections from the VTK, Slicer3 and CUDA frameworks.

Description:
 
* The Fat line displays the pipeline flow.
 
* Green colored fields are classes from the Slicer3 or vtk implementation
 
* Red colored fields are CUDA and hardware specific parts
 
* Blue colored fields are specially implemented parts for the communication of cuda and vtk and the volume rendering algorithms.
