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)	Compare the architectures of different existing projects where parts of the required functionality has been implemented: Ibis Neuronav/PRISM (Multi-volume ray-casting with progammable shaders in VTK) Steve Piepers volume processing on the GPU with GLSL (Steve, please write something smarter here) CustusX (GPU volume slicing and compositing with multi-window context sharing) Determine a sensible way to integrate all those contribution in VTK.
