| − | The goal of this project is to implement a CUDA based Volume Rendering Technique inside of [http://www.vtk.org VTK] and Slicer3.
| |
| − | | |
| − | | |
| − | == Project Outline ==
| |
| − | Several steps have to be made to integrating a CUDA based volume rendering technique into vtk.
| |
| − | #Integrate '''CUDA runtime API''' support into VTK using a class based approach.
| |
| − | #Implement and Integrate a '''CUDA Volume Rendering algorithm'''.
| |
| − | #Integrate the algorithm into a '''VTK pipeline''' (described below)
| |
| − | #Create a '''user interface''' to control the flow of the Volume Rendering within Slicer3.
| |
| − | | |
| − | == VTK Cuda Runtime API support ==
| |
| − | The c-interface to the CUDA objects and functions will be wrapped as described on the following pages:
| |
| − | *[[VTK Cuda Wrapper Classes]]
| |
| − | *[[VTK Cuda Memory Management Classes]]
| |
| − | | |
| − | == Cuda Volume Rendering Algorithm == | |
| − | The Code that we use so far has been implemented by Nicholas Harlambang and can be viewed at [http://svn.orxonox.net/subprojects/volrenSample]. | |
| − | | |
| − | == VTK Modules and Pipeline ==
| |
| − | These are the modules that will be created in order to integrate a Cuda based Volume Rendering into the Slicer3 pipeline
| |
| − | # '''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.
| |
| − | | |
| − | == A Slicer3 User Interface ==
| |
| − | The GUI will be designed using KWWidgets. With this the user will be able to change the rendering resolution, step size, control the color sceme and load and store further information.
| |
| − | | |
| − | == Tasks ==
| |
| − | #Proof of concept
| |
| − | #Integrate into VTK
| |
| − | ##Render the output from the code of Nicholas [http://svn.orxonox.net/subprojects/volrenSample volume render sample] into vtkImageViewer
| |
| − | ##Adapt to Z-buffer
| |
| − | ##Adapt lighting model
| |
| − | ##Adapt to input Image
| |
| − | #Integration into Slicer
