《基于MFC的OpenGL编程》Part 19 Creating a Virtual Reality Walkthrough Application

        本文是整个系列文章的最后一篇，将创建一个完整的虚拟office应用程序(如图所示)来做为ending.

1,在CCY457OpenGLView类中加入下述变量，用来保存office内各个物体的显示列表

     // Display List Names
    GLuint m_SceneList;
    GLuint m_ComputerList;
    GLuint m_ChairList;
    GLuint m_BlindsList;
    GLuint m_MonitorList;
    GLuint m_BooksList;
    GLuint m_PhoneList;
    GLuint m_DoorList;

2，创建房间内部场景

// Create the Display List for the Scene
void  CCY457OpenGLView::CreateSceneList()
{
    m_SceneList  =  glGenLists( 1 );
    glNewList(m_SceneList, GL_COMPILE);
     /* *****************Setup Lighting********************* */
    SetupLighting();
     /* **************Draw the Scene************************ */
     // Draw the Walls
    DrawWalls();            
     // Draw the Wall Tops, Sides and Desks
    DrawWallTopsAndSides();
     // Draw the desks
    DrawDesks();
     // Draw the computers
    DrawComputers();    
     // Draw the Chairs
    DrawChairs();
     // Draw the Blinds
    DrawBlinds();
     // Draw Phones
    DrawPhones();
     // Draw Floor and Ceiling
    DrawFloorAndCeiling();
    glEndList();
}

3,从Obj文件中加载各个物件的3D模型

// Load all the Models from the Files of type .obj
void  CCY457OpenGLView::LoadModelsFromFiles()
{
    GLfloat scalefactor  =   0.0 ;
     // Load Computer from file
    GLMmodel  * object1;
    object1  =  glmReadOBJ( " Data/models/computer.obj " );
     if ( ! scalefactor) 
    {
        scalefactor  =  glmUnitize(object1);
    } 
     else  
    {
        glmScale(object1, scalefactor);
    }
    glmScale(object1,  1.5 );    
     /*  build a display list  */
    m_ComputerList  =  glmList(object1, GLM_SMOOTH);
     /*  nuke it, we don't need it anymore  */
    glmDelete(object1);    
     // Load Chair From File
    GLMmodel  * object2;
    scalefactor  =   0.0 ;
    object2  =  glmReadOBJ( " Data/models/chair04.obj " );
     if ( ! scalefactor) 
    {
        scalefactor  =  glmUnitize(object2);
    } 
     else  
    {
        glmScale(object2, scalefactor);
    }
    glmScale(object2,  2.5 );    
     /*  build a display list  */
    m_ChairList  =  glmList(object2, GLM_SMOOTH);
     /*  nuke it, we don't need it anymore  */
    glmDelete(object2);    
     // Load Blinds Object From File
    GLMmodel  * object3;
    scalefactor  =   0.0 ;
    object3  =  glmReadOBJ( " Data/models/blinds.obj " );
     if ( ! scalefactor) 
    {
        scalefactor  =  glmUnitize(object3);
    } 
     else  
    {
        glmScale(object3, scalefactor);
    }
    glmScale(object3,  1.0 );    
     /*  build a display list  */
    m_BlindsList  =  glmList(object3, GLM_SMOOTH);
     /*  nuke it, we don't need it anymore  */
    glmDelete(object3);    
     // Load Books Object from file
    GLMmodel  * object4;
    scalefactor  =   0.0 ;
    object4  =  glmReadOBJ( " Data/models/books.obj " );
     if ( ! scalefactor) 
    {
        scalefactor  =  glmUnitize(object4);
    } 
     else  
    {
        glmScale(object4, scalefactor);
    }
    glmScale(object4,  1.2 );    
     /*  build a display list  */
    m_BooksList  =  glmList(object4, GLM_SMOOTH);
     /*  nuke it, we don't need it anymore  */
    glmDelete(object4);    
     // Load Monitor from file
    GLMmodel  * object5;
    scalefactor  =   0.0 ;
    object5  =  glmReadOBJ( " Data/models/samsung.obj " );
     if ( ! scalefactor) 
    {
        scalefactor  =  glmUnitize(object5);
    } 
     else  
    {
        glmScale(object5, scalefactor);
    }
    glmScale(object5,  0.20 );    
     /*  build a display list  */
    m_MonitorList  =  glmList(object5, GLM_SMOOTH);
     /*  nuke it, we don't need it anymore  */
    glmDelete(object5);    
     // Load Phone Object from file
    GLMmodel  * object6;
    scalefactor  =   0.0 ;
    object6  =  glmReadOBJ( " Data/models/phone.obj " );
     if ( ! scalefactor) 
    {
        scalefactor  =  glmUnitize(object6);
    } 
     else  
    {
        glmScale(object6, scalefactor);
    }
    glmScale(object6,  0.08 );    
     /*  build a display list  */
    m_PhoneList  =  glmList(object6, GLM_SMOOTH);
     /*  nuke it, we don't need it anymore  */
    glmDelete(object6);        
}

4，创建各个具体物件的代码:
