(4)小遊戲 (回家作業)
------------------------------------------

 

課堂作業: 顯示出足球

(1) http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/ 下載

[source]→下載\window\ glm.c glm.h transformation.c
[data]→下載\window\data\soccerball.obj-{v vn vt}  soccerball.mtl - 色彩
[win32]→下載\window\transformation.exe
glut32.dll→下載\window\gkut32.dll

 

開啟後把資料放在window裡面

顯示足球模型



(2)用右鍵Notepad++開啟 soccerball.obj  soccerball.mtl

 

 

 

 

(3) 用程式碼顯示3D模型

     1.myGLMsample.zip 解壓縮

     2.裝freeglut  (在桌面)

     3.開啟04160011_hw1.cbp

  



 更改圖形

 

 

程式碼  :

#include <string.h>
#include <stdlib.h>
#include <GL/glut.h>

#include "glm.h"  ///(1) include .h檔
GLMmodel* pmodel = NULL; ///(2)3D模型的變數 ,Ctrl-F找glm
float angle=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        angle++;
        glRotatef(angle, 0,1,0);
        if (!pmodel)   ///如果模型還沒讀好, NULL, !pmodel

       {

        pmodel = glmReadOBJ("data/porsche.obj");  ///(3)讀模型
        if (!pmodel) exit(0);  ///如果模型還沒讀好 , NULL GG 閃退 離開

        glmUnitize(pmodel);  ///變成單位大小的模型,才不會太大

        glmFacetNormals(pmodel);  ///小面的法向量重算
        glmVertexNormals(pmodel, 90.0);  ///頂點法向量
        }

        glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

    glPopMatrix();
    glutSwapBuffers();
}
const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };
const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_position[] = { 2.0f, 5.0f, -5.0f, 0.0f };

const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };

const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };
const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat high_shininess[] = { 100.0f };

int main(int argc, char**argv)

{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH | GLUT_RGB);
    glutCreateWindow("Yes, 3D Model Here");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glClearColor(1,1,1,1);

    //glEnable(GL_CULL_FACE);
    //glCullFace(GL_BACK);

    glEnable(GL_DEPTH_TEST);

    glDepthFunc(GL_LESS);

    glEnable(GL_LIGHT0);

    glEnable(GL_NORMALIZE);
    glEnable(GL_COLOR_MATERIAL);
    glEnable(GL_LIGHTING);

    glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);

    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);
    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);
    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);

    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);
    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);
    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMainLoop();

}

• google 搜尋 →NeHe lesson32

執行lesson32.exe應用程式(不要Fullscreen)

 

遊戲顯示圖

• 如何用出聲音

在lesson32.cpp找sound 槍聲
PlaySound("檔名.wav",NULL,SND-ASYNC );





 

 

聲音檔路徑

 

 

老師上課節圖

 

• 用鍵盤發出鋼琴聲音

        (1)壓縮FB社團裡面的Music.zip檔把Do ReMi 的聲音複製到myGLMsample資料夾裡

        (2)加入keyboard的程式碼:

void keyboard(unsigned char key ,int x, int y)                       
{                                                                                              
    if(key=='1')PlaySound("Do.wav",NULL,SND_ASYNC);
    if(key=='2')PlaySound("Re.wav",NULL,SND_ASYNC);
    if(key=='3')PlaySound("Mi.wav",NULL,SND_ASYNC);
    if(key=='4')PlaySound("Fa.wav",NULL,SND_ASYNC); 
    if(key=='5')PlaySound("So.wav",NULL,SND_ASYNC); 

}
