Project Description

Objective Move forward on a set of code to do GPU computing with multiple target platforms in mind as described in these slides and videos.	Approach, Plan 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	Progress
