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
复制代码
//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;
复制代码
2，创建房间内部场景
复制代码
//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();
}
复制代码
3,从Obj文件中加载各个物件的3D模型
复制代码
//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);
}
