OpenCascade Modeling Algorithms Boolean Operations
Modeling Algorithms Boolean Operations of Opencascade
布尔操作(Boolean Operations)是通过两个形状(S1,S2)的组合来生成新的形状。布尔操作有如下几种类型:
u 并集操作Fusion:Gets all the points in S1 or S2;
u 交集操作Common:Gets all the points in S1 and S2;
u 差集操作Cut S1 by S2:Gets all the points in S1 and not in S2;
下图所示为三种布尔操作:
1. BRepAlgoAPI_BooleanOperation
类BRepAlgoAPI_BooleanOperation是布尔操作的基类。
2. BRepAlgoAPI_Fuse
类BRepAlgoAPI_Fuse执行布尔并集操作。如下所示:
TopoDS_Shape theBox1 = BRepPrimAPI_MakeBox(,,);
TopoDS_Shape theBox2 = BRepPrimAPI_MakeBox(-,,);
TopoDS_Shape FusedShape = BRepAlgoAPI_Fuse(theBox1,theBox2);
Fuse two boxes
3. BRepAlgoAPI_Common
类BRepAlgoAPI_Common执行布尔交集操作,如下所示:
gp_Ax2 axe(gp_Pnt(,,),gp_Dir(,,)); TopoDS_Shape theBox = BRepPrimAPI_MakeBox(axe,,,);
TopoDS_Shape theWedge = BRepPrimAPI_MakeWedge(.,.,.,.);
TopoDS_Shape theCommonSurface = BRepAlgoAPI_Common(theBox,theWedge);
Compute the common surface
4. BRepAlgoAPI_Cut
类BRepAlgoAPI_Cut执行布尔差集操作,如下所示:
TopoDS_Shape theBox = BRepPrimAPI_MakeBox(,,);
TopoDS_Shape theSphere = BRepPrimAPI_MakeSphere(gp_Pnt(,,),);
TopoDS_Shape ShapeCut = BRepAlgoAPI_Cut(theSphere,theBox);
5. BRepAlgoAPI_Section
