VTK 7 will follow very shortly (in weeks). I'd like to shed some light here on our thinking and how we are planning to move forward.</div><div><br></div><div>As was previously discussed in the VTK developers list [1] [2], we are considering maintaining VTK 6.x for a long time (3-5 years) while moving forward with VTK 7 and 8 in 2015 and 2016. There are some major changes happening in the computing and C++ worlds and we would like evolve VTK more quickly to stay up to date. Some of the major changes that we are considering and/or working on are:</div><div><br></div><div>* Major refactoring of rendering (OpenGL as well as ray tracing etc.)</div><div>* Multi/many-core support / SMP computing on CPUs and accelerators. VTK-m integration [3].</div><div>* Changes to data model to support zero copy interface to other data layouts, more efficient APIs, more cell types, more dataset types etc.</div><div>* Better separation of a public, wrapped API and toolkit/C++ internal API mainly to support efficiency</div><div>* Introduction of C++ 11 features</div><div><br></div><div>Much of this will require introducing changes that break backwards compatibility and also require newer compilers, graphics cards / drivers etc. So the idea is that we will do our best to support as much as possible a broad set of architectures and backwards compatibility but break things when necessary in VTK 7 and beyond. We will maintain VTK 6.x so that folks that are stuck on legacy systems or code bases can continue to benefit from bug fixes. We have a way of continuing to maintain a broad set of dashboards and also the same review process as VTK master so that we can continue to ensure the quality of VTK 6.x as well as new releases.</div><div><br></div><div>What do you guys think? Please provide feedback so that we can adjust our plans to meet the needs of the community as much as possible.</div><div><br></div><div><div>Best,</div><div>-berk</div></div><div><br></div><div>[1] : <a href="http://bit.ly/1BUHFKT" target="_blank">http://bit.ly/1BUHFKT</a></div><div>[2] : <a href="http://bit.ly/1g7LSRG" target="_blank">http://bit.ly/1g7LSRG</a></div><div>[3] : <a href="http://m.vtk.org/" target="_blank">http://m.vtk.org/</a></div><div><br></div><div><br></div></div>
