炸天的3D引擎OpenCASCADE的用法及案例(https://blog.csdn.net/xipengbozai/article/details/117044032?spm=1001.2014.3001.5502)
What CASCADE？
Open CASCADE（簡稱OCC）平台是由法國Matra Datavision公司開發的CAD/CAE/CAM軟體平台，可以說是世界上最重要的幾何造型基礎軟體平台之一。開源OCC對象庫是一個面向對象C++類庫，用於快速開發設計領域的專業應用程式。
用它可以做很多三維模型，如下面兩種。簡單地說它可以開發三維CAD或者Solidworks等等軟體，可以說強大無比。
OpenCASCADE的下載與安裝
1.OpenCASCADE下載。
1）去官網下載：//dev.opencascade.org/release
2）去CSDN下載：//download.csdn.net/download/xipengbozai/18883824
3）下載你需要的版本，推薦下載安裝版，比較省事：//download.csdn.net/download/xipengbozai/18883824
2.OpenCASCADE安裝。
1）匹配VS版本，我的是VS2017 64位版本，所以安裝的是opencascade-7.4.0-vc14-64.exe
2）單機安裝，選擇下一步
3）然後安裝full版本，也就是完全版，單擊安裝直到完成即可。
4）安裝完的目錄效果，opencascade-7.4.0是主目錄，其他是附加庫
OpenCASCADE的用法
1.建立項目工程，包含目錄
2.添加庫目錄，如下所示
3.鏈接器-輸入-附加依賴項輸入如下項

3.mfcoccc.h文件中創建三維引擎句柄，
Handle(Graphic3d_GraphicDriver) m_GraphicDriver;
Handle(Graphic3d_GraphicDriver) GetGraphicDriver() { return m_GraphicDriver; }
4.mfcocccDoc.h文件中聲明上下文和顯示view句柄，繪圖函數聲明
Handle(AIS_InteractiveContext) myAISContext; Handle(V3d_Viewer) myViewer; Handle(V3d_Viewer) GetViewer(void) { return myViewer; } void DrawSphere(double Radius); void DrawBox(double MyHeight,double MyWidth,double MyThickness); //畫盒子5.mfcocccView.h中聲明視圖句柄
Handle(V3d_View) myView;6.實現程式碼較多，這裡就不一一列出來了
7.案例達到的效果如下，是一個立體的空瓶子。
