一.下载OpenCASCADE
官网下载是： http://www.opencascade.org/getocc/download/loadocc/
我的百度云已经下载好的是：

下载后运行完毕就是这样：
二.VS2017 MFC单文档配置OpenCASCADE 环境
先将每个文件夹里的bin文件夹都添加到系统的环境变量里
然后在将bin文件夹内的dll文件全部复制一份放在C:\Windows\SysWOW64里（注意我这里是64位的）你们32就放32里
在VS2017中创建一个单文档MFC项目，我的命名是OCCmfc
然后在项目属性里：
将你们自己路径下的！！包含目录，和库目录都添加上去（看图！！）
然后在连接器-》输入-》附加依赖项里添加下面这些Lib文件名：
TKBin.lib TKBinL.lib TKBinTObj.lib TKBinXCAF.lib TKBO.lib TKBool.lib TKBRep.lib TKCAF.lib TKCDF.lib TKD3DHost.lib TKDCAF.lib TKDFBrowser.lib TKDraw.lib TKernel.lib TKFeat.lib TKFillet.lib TKG2d.lib TKG3d.lib TKGeomAlgo.lib TKGeomBase.lib TKHLR.lib TKIGES.lib TKIVtk.lib TKIVtkDraw.lib TKLCAF.lib TKMath.lib TKMesh.lib TKMeshVS.lib TKOffset.lib TKOpenGl.lib TKPrim.lib TKQADraw.lib TKRWMesh.lib TKService.lib TKShapeView.lib TKShHealing.lib TKStd.lib TKStdL.lib TKSTEP.lib TKSTEP209.lib TKSTEPAttr.lib TKSTEPBase.lib TKSTL.lib TKTInspector.lib TKTInspectorAPI.lib TKTObj.lib TKTObjDRAW.lib TKToolsDraw.lib TKTopAlgo.lib TKTopTest.lib TKTreeModel.lib TKV3d.lib TKVCAF.lib TKView.lib TKViewerTest.lib TKVInspector.lib TKVRML.lib TKXCAF.lib TKXDEDRAW.lib TKXDEIGES.lib TKXDESTEP.lib TKXMesh.lib TKXml.lib TKXmlL.lib TKXmlTObj.lib TKXmlXCAF.lib TKXSBase.lib TKXSDRAW.lib
然后打开项目后在stdafx.h中添加这些要用到的头文件：
#include <BRepTools.hxx> #include <Standard_DefineHandle.hxx> #include <DsgPrs_LengthPresentation.hxx> #include <GCPnts_TangentialDeflection.hxx> #include <Geom_Axis2Placement.hxx> #include <Geom_CartesianPoint.hxx> #include <Geom_Line.hxx> #include <Geom_Surface.hxx> #include <BRepAdaptor_Surface.hxx> #include <GeomAbs_CurveType.hxx> #include <GeomAdaptor_Curve.hxx> #include <GeomTools_Curve2dSet.hxx> #include <gp_Vec.hxx> #include <Graphic3d_NameOfMaterial.hxx> #include <MMgt_TShared.hxx> #include <OSD_Environment.hxx> #include <Precision.hxx> #include <Prs3d_IsoAspect.hxx> #include <Prs3d_LineAspect.hxx> #include <Prs3d_Projector.hxx> #include <Prs3d_Text.hxx> #include <Quantity_Factor.hxx> #include <Quantity_Length.hxx> #include <Quantity_NameOfColor.hxx> #include <Quantity_PhysicalQuantity.hxx> #include <Quantity_PlaneAngle.hxx> #include <Quantity_TypeOfColor.hxx> #include <SelectMgr_EntityOwner.hxx> #include <SelectMgr_SelectableObject.hxx> #include <SelectMgr_Selection.hxx> #include <SelectMgr_SelectionManager.hxx> #include <SelectMgr_ListOfFilter.hxx> #include <SelectMgr_Filter.hxx> #include <StdSelect_EdgeFilter.hxx> #include <StdSelect_ShapeTypeFilter.hxx> #include <Standard_Boolean.hxx> #include <Standard_CString.hxx> #include <Standard_ErrorHandler.hxx> #include <Standard_Integer.hxx> #include <Standard_IStream.hxx> #include <Standard_Macro.hxx> #include <Standard_NotImplemented.hxx> #include <Standard_OStream.hxx> #include <Standard_Real.hxx> #include <StdPrs_Curve.hxx> #include <StdPrs_Point.hxx> #include <StdPrs_PoleCurve.hxx> #include <TCollection_AsciiString.hxx> #include <TColgp_Array1OfPnt2d.hxx> #include <TColgp_HArray1OfPnt2d.hxx> #include <TCollection_AsciiString.hxx> #include <TColStd_HSequenceOfTransient.hxx> #include <TColStd_MapIteratorOfMapOfTransient.hxx> #include <TColStd_MapOfTransient.hxx> #include <TopExp_Explorer.hxx> #include <TopoDS.hxx> #include <TopoDS_Compound.hxx> #include <TopoDS_Shape.hxx> #include <TopoDS_Solid.hxx> #include <TopoDS_Vertex.hxx> #include <TopExp.hxx> #include <TopTools_HSequenceOfShape.hxx> #include <UnitsAPI.hxx> #include <V3d_View.hxx> #include <V3d_Viewer.hxx> #include <WNT_Window.hxx> #include <Prs3d_PointAspect.hxx> #include <AIS_Point.hxx> #include <AIS_InteractiveContext.hxx> #include <AIS_Shape.hxx> #include <BRep_Tool.hxx> #include <BRepAlgoAPI_Fuse.hxx> #include <BRepBuilderAPI_MakeEdge.hxx> #include <BRepBuilderAPI_MakeFace.hxx> #include <BRepBuilderAPI_MakeWire.hxx> #include <BRepBuilderAPI_MakeVertex.hxx> #include <BRepBuilderAPI_Transform.hxx> #include <BRepPrimAPI_MakeCone.hxx> #include <BRepPrimAPI_MakeRevol.hxx> #include <BRepFilletAPI_MakeFillet.hxx> #include <BRepBuilderAPI_Copy.hxx> #include <BRepBuilderAPI_MakePolygon.hxx> #include <BRepLib.hxx> #include <BRepOffsetAPI_MakeThickSolid.hxx> #include <BRepOffsetAPI_ThruSections.hxx> #include <BRepPrimAPI_MakeCylinder.hxx> #include <BRepPrimAPI_MakePrism.hxx> #include <BRepPrimAPI_MakeTorus.hxx> #include <BRepAlgoAPI_Section.hxx> #include <BRepPrimAPI_MakeSphere.hxx> #include <BRepFeat_SplitShape.hxx> #include <TColgp_HArray1OfPnt.hxx> #include <GeomAPI_Interpolate.hxx> #include <GC_MakeArcOfCircle.hxx> #include <GC_MakeSegment.hxx> #include <GC_MakeCircle.hxx> #include <GCE2d_MakeSegment.hxx> #include <gp.hxx> #include <gp_Ax1.hxx> #include <gp_Ax2.hxx> #include <gp_Ax2d.hxx> #include <gp_Dir.hxx> #include <gp_Dir2d.hxx> #include <gp_Pnt.hxx> #include <gp_Pnt2d.hxx> #include <gp_Trsf.hxx> #include <gp_Vec.hxx> #include <Geom_CylindricalSurface.hxx> #include <Geom_Plane.hxx> #include <Geom_Surface.hxx> #include <Geom_TrimmedCurve.hxx> #include <Geom2d_Ellipse.hxx> #include <Geom2d_TrimmedCurve.hxx> #include <TopExp_Explorer.hxx> #include <TopoDS.hxx> #include <TopoDS_Edge.hxx> #include <TopoDS_Face.hxx> #include <TopoDS_Wire.hxx> #include <TopoDS_Shape.hxx> #include <TopoDS_Compound.hxx> #include <GCPnts_AbscissaPoint.hxx> #include <BRepAdaptor_Curve.hxx> #include <GeomLib.hxx> #include <GeomConvert_CompCurveToBSplineCurve.hxx> #include <TopTools_ListOfShape.hxx> #include <TopTools_ListIteratorOfListOfShape.hxx> #include <TopTools_DataMapOfShapeInteger.hxx> #include <TopTools_DataMapOfShapeReal.hxx> #include <TopTools_IndexedDataMapOfShapeAddress.hxx> #include <V3d_PositionalLight.hxx> #include <V3d_DirectionalLight.hxx> #include <V3d_AmbientLight.hxx> #include <IGESControl_Controller.hxx> #include <IGESControl_Writer.hxx> #include <Interface_Static.hxx> #include <OpenGl_GraphicDriver.hxx> #include <Graphic3d_GraphicDriver.hxx>
然后在OCCmfc.h文件的类里添加：
Handle(Graphic3d_GraphicDriver) m_GraphicDriver;
Handle(Graphic3d_GraphicDriver) GetGraphicDriver() { return m_GraphicDriver; }
在OCCmfc.cpp的构造函数里加上：
try {
Handle(Aspect_DisplayConnection) aDisplayConnection;
m_GraphicDriver = new OpenGl_GraphicDriver(aDisplayConnection);
}
catch (Standard_Failure) {
AfxMessageBox(L"(Error Ocured in Initializing the Opencascade graphic variable.)");
}
注意！！！如果new字符报错，那么是因为opencascade对new进行了重载，我们将每个new报错文件顶部的：
#ifdef _DEBUG #define new DEBUG_NEW #endif
这几行代码注释就行了
接着在OCCmfcDoc.h文件类里添加：
Handle(AIS_InteractiveContext) myAISContext;
Handle(V3d_Viewer) myViewer;
Handle(V3d_Viewer) GetViewer(void) {return myViewer;}
接着去实现文档OCCmfcDoc.cpp中类的构造函数中添加：
Handle(Graphic3d_GraphicDriver) theGraphicDriver = ((CmOCCTApp*)AfxGetApp())->GetGraphicDriver();
myViewer = new V3d_Viewer(theGraphicDriver);
myViewer->SetDefaultLights();
myViewer->SetLightOn();
myAISContext = new AIS_InteractiveContext(myViewer);
myAISContext->SetDisplayMode(AIS_Shaded,true);
myAISContext->SetAutomaticHilight(Standard_False);
然后去去OCCmfcView.h定义类里添加：
Handle(V3d_View) myView;
和添加要重写的这个函数：
virtual void OnInitialUpdate();
然后去OCCmfcView.cpp文件里添加下面这个实现函数（随便添加在哪里）：
void COCCmfcView::OnInitialUpdate()
{
CView::OnInitialUpdate();
myView = GetDocument()->GetViewer()->CreateView();
myView->SetShadingModel(V3d_GOURAUD);
Handle(Graphic3d_GraphicDriver) theGraphicDriver = ((COCCmfcApp*)AfxGetApp())->GetGraphicDriver();
Aspect_Handle aWindowHandle = (Aspect_Handle)GetSafeHwnd();
Handle(WNT_Window) aWntWindow = new WNT_Window(GetSafeHwnd());
myView->SetWindow(aWntWindow);
if (!aWntWindow->IsMapped()) {
aWntWindow->Map();
}
Standard_Integer w = 100;
Standard_Integer h = 100;
aWntWindow->Size(w, h);
::PostMessage(GetSafeHwnd(), WM_SIZE, SIZE_RESTORED, w + h * 65536);
myView->FitAll();
myView->ZBufferTriedronSetup(Quantity_NOC_RED, Quantity_NOC_GREEN, Quantity_NOC_BLUE1, 0.8, 0.05, 12);
myView->TriedronDisplay(Aspect_TOTP_LEFT_LOWER, Quantity_NOC_WHITE, 0.2, V3d_ZBUFFER);
}
然后在这个文件中的OnDraw()函数中添加：
myView->MustBeResized(); myView->Update();
编译运行：
三.绘制图形
在OCCmfcDoc.h中添加
void DrawSphere(double Radius);
在OCCmfcDoc.cpp中添加函数（随便放哪）：
void COCCmfcDoc::DrawSphere(double Radius)
{
BRepPrimAPI_MakeSphere mkSphere(Radius);
TopoDS_Shape Sphere = mkSphere.Shape();
Handle(AIS_Shape) myAISSphere = new AIS_Shape(Sphere);
myAISContext->Display(myAISSphere, Standard_False);
CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
CMDIChildWnd *pChild = (CMDIChildWnd *)pFrame->GetActiveFrame();
COCCmfcView *pView = (COCCmfcView *)pChild->GetActiveView();
pView->FitAll();
}
然后在OCCmfcView.h中添加：
void FitAll() { if (!myView.IsNull()) myView->FitAll(); myView->ZFitAll(); };
最后在OCCmfcView.cpp文件里的OnDraw()函数里添加：
pDoc->DrawSphere(6);
然后运行如下所示 画了一个图形出来：
