Visual Studio 2013编译Triangle

1.Visual Studio 2013编译Triangle

下载Triangle源码解压，新建Windows控制台项目，导入triangle.h和triangle.c，如果不需要编译lib库，仅用命令行，则修改头文件如下：

#ifndef _TRIANGLE_HEADER_  
#define _TRIANGLE_HEADER_

#ifdef _cplusplus  
extern "C"{
#endif

#define REAL double  
#define ANSI_DECLARATORS  
#define VOID int  
#include "triangle.h"


struct triangulateio {
  REAL *pointlist;                                               /* In / out */
  REAL *pointattributelist;                                      /* In / out */
  int *pointmarkerlist;                                          /* In / out */
  int numberofpoints;                                            /* In / out */
  int numberofpointattributes;                                   /* In / out */

  int *trianglelist;                                             /* In / out */
  REAL *triangleattributelist;                                   /* In / out */
  REAL *trianglearealist;                                         /* In only */
  int *neighborlist;                                             /* Out only */
  int numberoftriangles;                                         /* In / out */
  int numberofcorners;                                           /* In / out */
  int numberoftriangleattributes;                                /* In / out */

  int *segmentlist;                                              /* In / out */
  int *segmentmarkerlist;                                        /* In / out */
  int numberofsegments;                                          /* In / out */

  REAL *holelist;                        /* In / pointer to array copied out */
  int numberofholes;                                      /* In / copied out */

  REAL *regionlist;                      /* In / pointer to array copied out */
  int numberofregions;                                    /* In / copied out */

  int *edgelist;                                                 /* Out only */
  int *edgemarkerlist;            /* Not used with Voronoi diagram; out only */
  REAL *normlist;                /* Used only with Voronoi diagram; out only */
  int numberofedges;                                             /* Out only */
};

#ifdef ANSI_DECLARATORS
void triangulate(char *, struct triangulateio *, struct triangulateio *,
                 struct triangulateio *);
void trifree(VOID *memptr);
#else /* not ANSI_DECLARATORS */
void triangulate();
void trifree();
#endif /* not ANSI_DECLARATORS */

#ifdef _cplusplus  
}
#endif
#endif

修改triangle.c文件，主要是加入宏定义：

#define NO_TIMER
#define CPU86

如果不需要编译lib库，不要打开#define TRILIBRARY宏定义，否则会找不到main函数无法生成triangle.exe文件，修改完成后生成即可。

2.CentOS编译showme

Triangle生成的三角网格需要用showme可视化，但是该软件只能在X Windows下使用，所以在CentOS下编译showme，首先需要安装X11相关的库，执行yum install libX11-devel安装完成后执行cc -O -o showme showme.c -lX11对showme进行编译，生成相应的执行文件，可以对Triangle生成的任意文件进行显示，例如显示face.poly的分割结果face.1.ele，使用命令./showme face.1.ele即可显示。
