Hi everyone, <br><br>I have a surface rendering of an object, and I allow the user to pick points on the surface. The applicaton starts region-growing segmentation using the seed points picked. I want to restrict the region growing process by allowing the user to define/draw out a cubical box on the rendering window, beyond which the region cant grow. Does anyone know how I could go about doing this.
