2014-10-15 22:20:19 -0600 | asked a question | Motivation behind VizImpl Just noticed that, in the viz module, the implementation of the functions of the Viz3d class is not realized inside the class. Instead, it is implemented in a VizImpl struct which itself is a private member of the Viz3d class. So whenever an Viz3d function is called, that dummy Viz3d function calls the real VizImpl function instead. I'm just purely curious about the initial consideration of implementing it this way. Thank you! |

But PCL has had one implemented at http://docs.pointclouds.org/1.7.1/classpcl_1_1visualization_1_1_point_picking_event.html, if you don't mind integrating with one more library.. |

2014-10-14 20:02:49 -0600 | commented question | Segfault on quitting viz3d using the 'q' key @StevenPuttemans, these keys are defined in "4 vtkInteractorStyle::OnChar vtkInteractorStyle.cxx" which is inside "VTK-6.1.0/Rendering/core/". It seems like something went wrong between VTK and viz3d. |
2014-10-13 16:20:04 -0600 | commented question | Structure from Motion Considering the licensing, I think it is impossible to take the existing SfM source code as is and integrate into OpenCV. OpenCV is under BSD and the SfM programs above are GPL, and they are not compatible. But the integration is possible the other way around though, I mean, license-wise.. cmiiw |

2014-10-12 21:58:55 -0600 | asked a question | Segfault on quitting viz3d using the 'q' key The same problem occurred on both of my Ubuntu and Windows machines, i.e., when I run the viz3d tutorial example and hit the 'q' key to quit, exceptions are thrown. But if I press 'e' instead, no error happens. So for Windows, I have Windows-8_x64 + qt-5.3 + vtk-6.1.0 + opencv-2.4.10. When I run the example, the error is like:
And the Visual Studio debugger takes me to the function in vizimpl.cpp: For Ubuntu, I have Ubuntu-12.04_x64 + qt-5.0.2 + vtk-6.1.0 + opencv-2.4.9, and the error is "Segmentation fault (core dumped)". The stack of the QtCreator debugger GDB offered more insight:
So does someone have any idea, or get the same error? Could this be some bug in the viz module? |
