Public Attributes | |
vpImage< unsigned char > | I |
This class enables real time drawing of 2D or 3D graphics. An instance of the class open a window which contains between 1 and 4 graphics. Each one contains a desired number of curves.
The example below shows how to use the vpPlot class. An other example provided in tutoral-ibvs-plotter.cpp and described in Tutorial: Real-time curves plotter tool shows how to use this class to plot in real-time some curves during an image-based visual servo.
