Member Function Documentation

template<typename _W >
_W cv::viz::Widget::cast ( )
inherited

Casts a widget to another.

// Create a sphere widget
viz::WSphere sw(Point3f(0.0f,0.0f,0.0f), 0.5f);
// Cast sphere widget to cloud widget
viz::WCloud cw = sw.cast<viz::WCloud>();
Note
3D Widgets can only be cast to 3D Widgets. 2D Widgets can only be cast to 2D Widgets.
