这是我自己写的从数据库中读出数据

#include "stdafx.h"
#include "Element.h"

//数据库变量

//链表头
CNode *g_pNodeHead;
CEdge *g_pEdgeHead;
CPolygon *g_pPolygonHead;
//CGtp *g_pGtpHead;
//CHexahedron *g_pHexahedronHead;


//外部点链表头
//CNode *g_pOutsideNodeHead;
//计数器

int g_nNodeNum;
int g_nEdgeNum;
int g_nPolygonNum;


//显示控制变量
float g_fXTranslation;
float g_fYTranslation;
float g_fZTranslation;
float g_fXZoom;
float g_fYZoom;
float g_fZZoom;
//容差变量

//边界变量
float g_fXMin;
float g_fYMin;
float g_fZMin;
float g_fXMax;
float g_fYMax;
float g_fZMax;

//层数控制变量
int g_nMaxLayer;



float xMin,yMin,xMax,yMax ,xTran,yTran;
//当前显示层控制变量
int g_nCurrentLayer;
//是否已经初始化过了
bool g_bInit;


//建模控制变量
bool g_bCreateTin;
