Access vtkActor construction object and append new data

I am working with VTK-6.1 and I want to create a single vtkActor using multiple vtkUnstructuredGrid. First I create the actor from a grid... vtkSmartPointer<vtkActor> create_actor() { vtkSmartPointer<vtkUnstructuredGrid> grid = create_grid_a(); auto mapper = vtkSmartPointer<vtkDataSetMapper>::New(); mapper->SetInputData(grid); auto actor = vtkSmartPointer<vtkActor>::New(); actor->SetMapper(mapper); actor->GetProperty()->SetColor(0.5, 0.5, 0.5); actor->GetProperty()->SetEdgeVisibility(1); return...

GetMousePosition return always 0

I have a simple question: why the following code: int p[2] = {0, 0}; vtkRenderWindow->GetInteractor()->GetMousePosition(&p[0], &p[1]); TRACE("Mouse position: %d.%d\n", p[0], p[1]); gave me always Mouse position: 0.0 ? It means a lot for me if I solve this problem !!! Could you help me a little bit, please ?...

VTK OpenGL objects (3D texture) access from CUDA‏

Is there any proper way to access the low level OpenGL objects of VTK in order to modify them from a CUDA/OpenCL kernel using the openGL-CUDA/OpenCL interoperability feature? Specifically, I would want to get the GLuint (or unsigned int) member from vtkOpenGLGPUVolumeRayCastMapper that points to the Opengl 3D Texture object...

How can I use CMake to link vtk library to multiple source file?

Here is a typical Cmakelist file with only one source file: cmake_minimum_required(VERSION 2.8) PROJECT(test) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(test MACOSX_BUNDLE test) if(VTK_LIBRARIES) target_link_libraries(test ${VTK_LIBRARIES}) else() target_link_libraries(test vtkHybrid vtkWidgets) endif() The above example is if I have test.cxx and CMakeLists.txt only. What do I do if I also have a test2.cxx source...

what is the difference in .SetInputConnection() and .SetInput()

I was learning vtk on http://www.uppmax.uu.se/docs/w/index.php/How_to_Read_vtk_Files with this example. I found there is no difference when using arrowGlyph.SetInput(reader.GetOutput()) or arrowGlyph.SetInputConnection(reader.GetOutputPort()) I know that Getoutput() gives you a vtkPolyData and GetOutputPort() gives you a vtkAlgorithmOuPut. But I don't know what is going on under the hood. Can they be used interchangeably?...

Loading Legacy vs. XML VTK Files with Three.js
