C++ (Cpp) Subdiv2D::locate Examples

Example #1

File: main.cpp Project: huangxiaojian/3DTo2D

static void locate_point( Mat& img, Subdiv2D& subdiv, Point2f fp, Scalar active_color )
{
	int e0=0, vertex=0;


	subdiv.locate(fp, e0, vertex);


	if( e0 > 0 )
	{
		int e = e0;
		do
		{
			Point2f org, dst;
			if( subdiv.edgeOrg(e, &org) > 0 && subdiv.edgeDst(e, &dst) > 0 )
				line( img, org, dst, active_color, 3);


			e = subdiv.getEdge(e, Subdiv2D::NEXT_AROUND_LEFT);
		}
		while( e != e0 );
	}

	draw_subdiv_point( img, fp, active_color );
}
