OCC几何求交(转)

作者:互联网

OCC求交工具:

(1)二维曲线求交:Geom2dAPI_InterCurveCurve

(2)三维曲线与曲面求交:GeomAPI_IntCS

(3)三维曲面与曲面求交:GeomAPI_IntSS

(4)三维曲线求交:(这里有点不太懂)通过GeomAPI_ExtremaCurveCurve用于两条曲线求机制,可用于三维曲线的求交

接口使用:

1 //求交
2 //以二维曲线求交为例
3 Handle(Geom2d_Line) l1 = new Geom2d_Line(gp_Pnt2d(0, 0), gp_Dir2d(1, 0));
4 Handle(Geom2d_Circle) l2 = new Geom2d_Circle(gp_Ax2d(gp_Pnt2d(0, 0), gp_Dir2d(0, 1)),5.0);
5 Geom2dAPI_InterCurveCurve intersector(l1, l2, Precision::Confusion());
6 for (int i = 1; i <= intersector.NbPoints(); i++) {
7     gp_Pnt2d interPoint = intersector.Point(i);
8     cout << "交点" << i << "为:(" << interPoint.X() << "," << interPoint.Y() << ")" << endl;
9 }
