Slicer3:Volume Rendering With Cuda

Objectives

Lookout

A Short description of the modules needed to integrate a CUDA based Volume Rendering into VTK

VTK Modules

1. An imageDataReader to read Volume data as any kind of Volume Data
2. A Filter converting from the reader output to a cuda-able DataSet
3. A new vtkDataSet call it vtkCudaDataSet, where I will put my Volume Data used by the _init(), _loadData() and _delete() functions
4. A new vtkVolumeMapper that renders the scene using the lighting model, a prepared Z buffer, a camera position and the before mentioned DataSet to produce a image using the _doRender() function and the _getResult() function to acquire the produced data.
   1. A vtkTexture and a Plane to render the result to
5. An actor that places the volume into the scene
6. Chain this pipeline together and attach it to a rendering window.

Tasks

1. Proof of concept
2. Integrate into VTK
   1. Render the output from the code of Nicholas volume render sample into vtkImageViewer
   2. Adapt to Z-buffer
   3. Adapt lighting model
   4. Adapt to input Image
3. Integration into Slicer
