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（简称OCC）平台是由法国Matra Datavision公司开发的CAD/CAE/CAM软件平台，可以说是世界上最重要的几何造型基础软件平台之一。开源OCC对象库是一个面向对象C++类库，用于快速开发设计领域的专业应用程序。

用它可以做很多三维模型，如下面两种。简单地说它可以开发三维CAD或者Solidworks等等软件，可以说强大无比。

OpenCASCADE的下载与安装
1.OpenCASCADE下载。
1）去官网下载：https://dev.opencascade.org/release

2）去CSDN下载：https://download.csdn.net/download/xipengbozai/18883824

3）下载你需要的版本，推荐下载安装版，比较省事：https://download.csdn.net/download/xipengbozai/18883824

2.OpenCASCADE安装。
1）匹配VS版本，我的是VS2017 64位版本，所以安装的是opencascade-7.4.0-vc14-64.exe

2）单机安装，选择下一步

3）然后安装full版本，也就是完全版，单击安装直到完成即可。

4）安装完的目录效果，opencascade-7.4.0是主目录，其他是附加库

OpenCASCADE的用法
1.建立项目工程，包含目录

2.添加库目录，如下所示

3.链接器-输入-附加依赖项输入如下项

4.添加头文件，一定要注意添加位置，#include <afxdisp.h> // MFC 自动化类之后，#ifndef _AFX_NO_OLE_SUPPORT之前的中间。

3.mfcoccc.h文件中创建三维引擎句柄，

4.mfcocccDoc.h文件中声明上下文和显示view句柄，绘图函数声明

Handle(V3d_View) myView;6.实现代码较多，这里就不一一列出来了

7.案例达到的效果如下，是一个立体的空瓶子。
