Qt.4.8 and Vtk.6.2 real time point cloud streaming issue.

  • Hello Everyone,

    I am using pcl libraries with Qt, and I have to render laser scanner data
    continuously in the qvtkWidget.
    But whenever i update qvtkWidget, on receiving the data, main windows gets hangs.

    This is the slot , where i receive the laser scanner data continuously,

    this is the code inside the SLOT OnGetDataXYZ().
    viewer->updatePointCloud (cloud, "cloud");

    Please any one suggest me, how to refresh qvtkwidget in QMainWindow, without any issue.

    I haven't used VTK yet but at what rate are you getting the data ? Is that data pre-processed ?
