Project Description

Objective Approach and Plan Progress and Next Steps

Develop a specification for the next generation of GPU volume processing and rendering in VTK and Slicer

The specification should support

  • Multiple input volumes for ray-casting and slice-based volume rendering
  • GPU-based volume slicing and compositing
  • Programmable volume rendering shader
  • Smart management of volumes in GPU memory
  • Possibility to run simple processing operations on the volume (e.g. Non-linear transforms)
  • Consider possible complications
    • GPU features not available / software only fallback
    • Volumes too big to for GPU memory

Compare the architectures of different existing projects where parts of the required functionality has been implemented:

Determine a sensible way to integrate all those contribution in VTK.
