Message-ID: The harm of keeping the list open is in splitting the attention of the community.

Having more sites/lists makes it harder for people with questions to search for answers in previous posts. I realize that is also an argument for not having started the VTK Discourse at all, but I think the advantages of Discourse (which we can and have debated) are greater than that of the mailing list.

Message-ID: I think my biggest concern is references to the old lists, including places in mailman where you can sign up. For me, a search of "vtk mailing lists" brings up the mailman user signup list #2 in the rankings: vtkusers Info Page and #3 in the rankings: vtk.org Mailing Lists with links to the user, developer, and vtkm lists. (Fortunately the #1 ranking is the Community Support | VTK page which links to the forums which is great.) Also I suspect that there are external courses, presentations, notes, etc. out there which refer to the mailman list(s). So I suggest that these mailman-related sign up sites etc are modified with with an informative redirect to VTK resources especially the forums. Right now you can sign up and it initially acts like expected..... this might generate some frustration in an unsuspecting user.

I would like to get the slice along x, y and z directions at center of pixel data block. Following are what I did. 1. create image pixel data of whole series : p3DImageData. 2. use vtkImageImporter to load p3DImageData; 3. use vtkImageReslice to get data from vtkImageImporter; 4. get slice along x,y,z. Following is the code. I used three 4x4 matrix to change direction and get images by using the same m_reslice. However, (1) the extent[6] are 0, regardless which direction is used; (2) when axialElements is used, I can get correct pixel data for display. But using coronalElements and sagittalElements generate messy pixel data in slice; Please help point out what is wrong in my code.

I'm having trouble running tests locally (static build of master on macOS 10.14). A bunch of tests fail because opengl implementation of classes are not available, e.g.: [image: image.png] Others crash on failing to create instances of vtkGPUInfoList for example. I guess I'm doing something that causes some modules not to be initialized properly when testing, but what? Could this be related to the new module system?

As long as VTK::RenderingOpenGL2 is in the TEST_DEPENDS section for a module, the linking and auto-initialization of the factories for the test executables should happen automatically. One caveat: I set CMAKE_OSX_DEPLOYMENT_TARGET:STRING=10.9 for my build, but I doubt that this would change anything.

One of my questions: some of my HeaderTest fail because there is more than one include in the header, even though many header files in VTK include more than one header without generating an error. For example, I have a header file with those includes: #include "vtkRenderingCoreModule.h" // For export macro #include "vtkObject.h" #include "vtkNew.h" which causes the test to fail. But many other header files have even more, e.g. vtkVolumeProperty.h: #include "vtkNew.h" // Needed for vtkNew #include "vtkRenderingCoreModule.h" // For export macro #include "vtkObject.h" and do not fail the HeaderTesting. Does the order matter? The test report says there are 2 includes, not counting "vtkRenderingCoreModule.h", I guess this one is never included in the count? There must be something obvious here that I don't see, but what? Thanks in advance. s. -------------- next part -------------- An HTML attachment was scrubbed...
