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: Ibis Neuronav/PRISM (Multi-volume ray-casting with programmable shaders in VTK) Steve Piepers volume processing on the GPU with OpenGL in VTK and GLSL and with WebGL (With Anna Fruehstueck) and WebGL2 CustusX (GPU volume slicing and compositing with multi-window context sharing) Determine a sensible way to integrate all those contribution in VTK.
