HC_EXTERNAL void HC_CDECL HC_Show_Shell HC_PROTO ((
HC_KEY, int *, HC_POINT *, int *, int *));
Returns the previous definition of a shell, as referenced by a key.
| key | - Unique numeric identifier pointing to a shell in the database. | |
| pcount | - Number of valid points in points. Returned to caller. Passed by reference always. | |
| points | - Vector of x-y-z triplets for the coordinates of the vertices to be used to build the shell. (A simple N x 3 array may also be used. Fortran callers should reverse the subscripts.) Returned to caller. Passed by reference always. | |
| flist_length | - Total number of integers in face_list. Returned to caller. Passed by reference always. | |
| face_list | - Encoded description of how to connect the points to build the faces of the shell. Returned to caller. Passed by reference always. |
返回shell的先前定义，由键引用。
参数：
key - 指向数据库中的shell的唯一数字标识符。
pcount - 点的有效点数。 返回到调用者。 通过引用总是。
点 - 用于构建外壳的顶点坐标的x-y-z三元组矢量。 （也可以使用一个简单的N×3数组，Fortran调用者应该反转下标。）返回到调用者。 通过引用总是。
flist_length - face_list中的整数的总数。 返回到调用者。 通过引用总是。
face_list - 如何连接点以构建shell的面的编码描述。 返回到调用者。 通过引用总是。
HC_EXTERNAL void HC_CDECL HC_Show_Shell_Size HC_PROTO ((
HC_KEY, int *, int *));
| key | - Unique numeric identifier pointing to a shell in the database. | |
| pcount | - Number of valid points in points. Returned to caller. Passed by reference always. | |
| flist_length | - Total number of integers in face_list. Returned to caller. Passed by reference always. |
例子：
int a,b,c;
const int q = hc;
HC_Show_Shell_Size(q,&a,&b);
HPoint *d = new HPoint[a];
int *e = new int[b];
HC_Show_Shell(q,&a,d,&b,e);
……
……
delete []d;
delete []e;
鼠标的选择模式：
LocalSetOperator(new HOpSelectArea(m_pHView));//正常选择
LocalSetOperator(new HOpObjectTranslate(m_pHView));//移动
LocalSetOperator(new HOpObjectRotate(m_pHView));//旋转
LocalSetOperator(new HOpObjectClash(m_pHView));//检测碰撞
设置是否显示顶点
HC_Open_Segment_By_Key (m_pHView->GetSceneKey());
HC_Set_Visibility ("markers only = on");
HC_Set_Visibility ("markers only = off");
HC_Close_Segment ();
操作对象
HC_Open_Segment_By_Key(HC_KShow_Owner_By_Key (hk));
HC_Translate_Object(x,y,z);//平移
HC_Rotate_Object(x,y,z);//绕中心旋转
HC_Rotate_Object_Offaxis(x,y,z,d);//饶任意轴旋转
HC_Close_Segment();
