* Move forward on a set of code to do GPU computing with multiple target platforms in mind as [https://docs.google.com/presentation/d/14FHNwZ4eZ222xZEqs1pAtygTcz3Cy6GYLXlk8ANyxnc/edit?usp=sharing described in these slides and videos].

'''Progress from 2016 Winter Project Week:'''
* Identify use cases that would be good for this approach
** Visualization
** Segmentation
** Registration
* Code review and refinement of Slicer OpenGL shader/texture classes
* Evaluate build and deployment issues on various platforms
* Test code performance on various platforms
* Implement one or more sample image algorithms and compare with CPU implementation
** Performance
** Ease of development, readability, maintainability...
** Scalability limits
* Discussed motivation and implementation options with many members of the community
** Positive feedback on goals and opportunity
** Potential use cases identified as possible points of collaboration (Sandy Wells, Terry Yoo, Dan Blezek, Curt Lisle, Sudhanshu Semwal...)
** Additional motivation from IGT projects
*** Real-time brain shift visualization for AMIGO neurosurgery
*** Interactive segmentation/volume rendering for SlicerHeart and other applications
* Code and architecture review
* Experimental compositing options (see sphere-subtract image above)
|
* Review of requirements, previous implementations, design options
* Goal to have a common set of functionality across applications (Slicer, CustusX, IBIS, MITK, etc...)
* General feeling that a dedicated project week for GPU volume rendering would be a good idea.
