Yesterday I committed a longstanding topic to change the VTK default to the OpenGL2 backend. While we have talked about this in general terms we never got down to specifics. A bunch of nightlies broke and I hope to work through that over the next day or two or chicken out and retreat :-) But...here is the gist, you can still set VTK_RENDERING_BACKEND to OpenGL or OpenGL2 as desired, existing settings will not change, we have only changed the default for cases where it has not been specified. We also have added a new setting named VTK_RENDERING_BACKEND_DEFAULT that lets applications set their preference (in their own CMakeLists file) for VTK while still allowing the user to override it with VTK_RENDERING_BACKEND. </p><p class="MsoNormal"> </p><p class="MsoNormal">If you have any questions etc please let me know.</p><p class="MsoNormal"> </p><p class="MsoNormal">Thanks</p><p class="MsoNormal">Ken</p><p class="MsoNormal"> </p><p class="MsoNormal"> </p><p class="MsoNormal"> </p><p class="MsoNormal">Ken Martin PhD</p><p class="MsoNormal">Chairman & CFO</p><p class="MsoNormal">Kitware Inc.</p><p class="MsoNormal">28 Corporate Drive</p><p class="MsoNormal">Clifton Park NY 12065</p><p class="MsoNormal"><a href="mailto:ken.martin@kitware.com"><span style="color:blue">ken.martin@kitware.com</span></a></p><p class="MsoNormal">919 869-8871 (w)</p><p class="MsoNormal"> </p><p class="MsoNormal"> </p><p class="MsoNormal">This communication, including all attachments, contains confidential and legally privileged information, and it is intended only for the use of the addressee.
