I’m working on custom slicer app and now I need to understand how to add volume in C++. For example I have Eigen::MatrixXf that can be represented as vtkImageData. To display my data I guess I need to call GetScene() (or GetMRMLScene() I don’t know exactly) and then call AddNode(myVtkImage). If s…

When your module is instantiated the scene is passed to both the module logic and widget classes and they can be accessed as this->GetMRMLScene() and this->mrmlScene(), respectively. All other classes should get the scene from these classes (e.g., the module widget sets the scene in its child widge…

Thank you! One another related question that has now appeared: If my module depends on my SlicerCAT library wich is added via slicerMacroBuildAppLibrary(NAME qColada ...) and thus should be called qColada, how can I find_package(qColada REQUIRED) from my loadable module’s CMakeLists? As I can see s…

find_package is for external packages. Within Slicer, the module libraries and headers are available as CMake variables. See for example, here how libraries of Subject Hierarchy and Markups modules are used in a SlicerIGT module.

I think now I see how this works. Variables marked mark_as_superbuild(...) are kept in SlicerConfig.cmake and thus I can use them to find my dependencies. Thank you!

Also I can see now that the target qColadaApp is defined as: if (TARGET qColadaApp) message("qColadaApp EXIST") endif() prints: qColadaApp EXIST But when I link this target qColadaApp to my module: set(MODULE_TARGET_LIBRARIES vtkSlicer${MODULE_NAME}ModuleLogic qSlicer${MODULE_NAME}ModuleWi…

I guess I have found a solution. I should have manually added include folders to my ColadaApp headers (and export header wich is in Slicer-build/Applications/ColadaApp: # Current_{source,binary} and Slicer_{Libs,Base} already included set(MODULE_INCLUDE_DIRECTORIES ${CMAKE_CURRENT_SOURCE_DIR}/Log…
