week17

     -glutInitWindowSize(400,400);//視窗大小

    -glutInitWindowPosition(0,0);//視窗位置

 

加入打光的程式碼

- 在main函式前面加入:

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 };

在mainloop();前面加入:

glEnable(GL_DEPTH_TEST);//深度測試

    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);

    -控制滑鼠glutMouseFunc(mouse);

                       glutMotionFunc(motion);

利用x和x的舊座標

-float angle[20]={};

int angleID=0;

-鍵盤按鍵void keyboard(unsigned char key, int x, int y )

{

    if(key=='0') angleID=0;

    if(key=='1') angleID=1;

    if(key=='2') angleID=2;

    if(key=='3') angleID=3;

    if(key=='4') angleID=4;

     if(key=='5') angleID=5;

     if(key=='6') angleID=6;

}

要記得在main函式裡面加glutKeyboardFunc(keyboard);才會有動作

-存檔、讀檔

fprintf(fout, "%.2f", angle[i]);

fscanf(fin, "%f",&angle[i]);

注意fscanf後面要加&angle[i]

-timer

void timer(int t)

{

    glutTimerFunc(30,timer,t+1);

    if(t%30==0){///每幾個frame,讀一筆新資料，如果要讓動畫更順要把t%多少提高

        for(int i=0;i<20;i++) angleOld[i]=angleNew[i];

        if(fin==NULL) fin=fopen("angle.txt", "r");

        for(int i=0;i<20;i++) fscanf(fin, "%f", &angleNew[i]);

        ///讀新資料前先備份

    }

    float alpha=(t%30)/30.0;///alpha內插

    for(int i=0;i<20;i++){

        angle[i]= alpha*angleNew[i]+(1-alpha)*angleOld[i];

    }

    glutPostRedisplay();///重畫畫面

}

最終程式碼:

#include <stdio.h>

float angleOld[20]={}, angleNew[20]={};

int angleID=0;

week16

 

-利用上禮拜的程式碼

新增void mouse(); void motion();

設x,oldx

動畫按0123並配合滑鼠移動能讓關節移動 

-再motion裡面新增程式碼:

    if(fout==NULL) fout=fopen("angle.txt", "w+");

    for(int i=0; i<20;i++) fprintf(fout, "%.1f", angle[i]);

    fprintf(fout, "\n");

    for(int i=0;i<20;i++) printf("%.1f", angle[i]);

    printf("\n");

可以看到關節移動的角度

-播放動畫 FILE * fin = NULL;

再timer裡面新增動畫指令 

-再keyboard()裡面新增save,read,play

利用key==' '; 用鍵盤上的s可以存檔 
儲存位置後再讀檔，並利用鍵盤上的r讀檔

讀檔後就能撥放了

-再timer新增內插 讓動畫更順

設float angleOld[20]={}, angleNew[20]={};

更新angle, 利用alpha 0~1中間進行angle[i]= alpha*angleNew[i]+(1-alpha)*angleOld[i];

程式碼:

#include <stdio.h>

#include <GL/glut.h>

float angle[20]={}, diff=2;

float angleOld[20]={}, angleNew[20]={};

int angleID=0;

int oldx=0;

        if(fin==NULL) fin=fopen("angle.txt", "r");

        for(int i=0;i<20;i++) fscanf(fin, "%f", &angleNew[i]);

        ///讀新資料前先備份

    }

    float alpha=(t%30)/30.0;

    for(int i=0;i<20;i++){

        angle[i]= alpha*angleNew[i]+(1-alpha)*angleOld[i];

timer

 -備份glut的程式碼(用notepad++)

glutSolidSphere(0.3,30,30);//實心

glutWireSphere(0.3,30,30);//線框

把timer函式加進來

void timer{}裡面坐要做的事情

這裡打的是把背景清成紅色

display();是重畫畫面

glutTimerFunc(要等的時間,timer,0);

float angle++;

設定角度，並加入程式碼

可以讓方塊旋轉，背景變色

int diff

這讓方塊能左右轉動

加一個手臂，讓手臂能再時間到的時候開始轉動

把手臂移到中心點

時間到了之後開始轉動

    glPushMatrix();

        glColor3f(1,1,1);

        glutSolidCube(0.4);

        glPushMatrix();

            glTranslatef( -0.2,0.2,0 );//掛到肩膀

            glRotatef(angle,0,0,1);//轉動

            glTranslatef(-0.1,0,0);//把手臂關節放到中心點

            drawArm1();

        glPopMatrix();

    glPopMatrix();

程式碼:

#include <GL/glut.h>

float angle=0;

void drawArm1()

{

    glPushMatrix();

        glScalef(1,0.5,0.5);

        glColor3f(0,0,1);

鋼彈模型

 -安裝opencv、GLUT

-把老師的bg.jpg、Diffuse.jpg下載並放在glut的bin裡面

-設定好codeblocks的compiler

利用老師網頁裡的範例 把diffuse的圖檔打開

-把剛剛放在glut/bin裡的jpg跟dll檔放到專案目錄裡 

-利用notepad++把檔案位置改成"."

-glm.c改檔名(cpp)>是

-gundam還沒切開.zip Diffuse.jpg,Gundam.obj,Gundam.mtl複製到專案目錄

-codeblocks重開，打開cbp檔，再add file(glm.cpp)

-右鍵transformation.c ,notepad++

-複製程式碼 

-編輯Diffuse.jpg (垂直翻轉)

-利用float angle喬角度

程式碼:

#include <opencv/highgui.h>

#include <opencv/cv.h>

#include <GL/glut.h>

#include "glm.h"

GLMmodel * pmodel = NULL;

GLMmodel * arm1 = NULL;

void

drawmodel(void)

{

    if (!pmodel) {

pmodel = glmReadOBJ("Gundam.obj");

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_TEXTURE);

}

GLuint id1, id2;

int myTexture(char * filename)

    id1 = myTexture("Diffuse.jpg");

    id2 = myTexture("bg.jpg");

    glEnable(GL_DEPTH_TEST);

    glutMainLoop();

}

鋼彈

 

一開始用3DEXPLOR打開老師給的鋼彈模型程式碼

然後另存cpp檔，放桌面

打開codeblocks的open GL專案

把裡面原本的main.cpp, remove之後

把剛剛另存的鋼彈模型程式碼跟圖檔放到codeblocks的檔案裡

open GL,add file把鋼彈模型打開

加入    #define GL_BGR_EXT 0x80E0 

    #define GL_BGRA_EXT 0x80E1

這兩行，並把palette兩行註解掉

把原本會自動放大縮小的程式改成只對y軸旋轉

將原本的glRotatef和glScalef註解

加入 glRotatef(nAngle,0,1,0);

    glScalef(3,3,3);

利用maya把模型切割

先把要切割的模型匯入

壓滑鼠右鍵選擇face面，把要切割的面選取

之後export selection選擇obj檔匯出

將原本的open GL專案關掉

把GLUT打開 

打光的程式碼留著

將cbp檔案用notepad++打開

把資料放到"."裡面 

可以讓資料跑到現在的位置

再把glut裡面的freeglut.dll拉到codeblocks的資料夾裡面

這樣就能成功了

程式碼:

#include <GL/glut.h>

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    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);

    glutCreateWindow("week12 hw4");

    glutDisplayFunc(display);

    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();

}

模型打光

 

一開始先下載data,windows,sources.zip

並把要加進去的檔案加入

把設定都設定好

可以打開老師的transformation視窗

之後把main裡面的程式碼全部刪除

copy其中的一部分程式碼並加入幾行新的程式碼

使用#include "glm.h"(要用雙引號)開外掛

程式碼:

#include "glm.h"

GLMmodel * pmodel=NULL;

void drawmodel(void)

{

    if(!pmodel){

        pmodel = glmReadOBJ("data/porsche.obj");

        if (!pmodel) exit(0);

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel,90.0);

    }

    glmDraw(pmodel,GLM_SMOOTH|GLM_MATERIAL);

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    drawmodel();

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160661");

    glutDisplayFunc(display);

    glutMainLoop();

}

反面

正面

    glPushMatrix();

        glRotatef(180,0,1,0);//對y軸旋轉180度

        drawmodel();

    glPopMatrix();

加入week08的打光程式碼，讓模型上色

*要記得加上glEnable(GL_DEPTH_TEST);3D偵測

不然會破圖

程式碼:

#include "glm.h"

GLMmodel * pmodel=NULL;

void drawmodel(void)

{

    if(!pmodel){

        pmodel = glmReadOBJ("data/porsche.obj");

        if (!pmodel) exit(0);

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel,90.0);

    }

    glmDraw(pmodel,GLM_SMOOTH|GLM_MATERIAL);

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(180,0,1,0);

        drawmodel();

    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);

    glutCreateWindow("08160661");

    glutDisplayFunc(display);

    glEnable(GL_DEPTH_TEST);

    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();

}

播放音效

 

今天上課教如何撥放音效

下載下來的音樂要放到執行目錄

(freeglut\bin裡面)

程式碼:

#include <windows.h>

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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);

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

播放mp3檔要先下載MP3_MCI檔案

並放在專案目錄裡面，下載mp3檔

程式碼:

#include <windows.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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);

}

int main(int argc, char**argv)

{

    mp3.Load("music.mp3");

    mp3.Play();

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

再增加一個按滑鼠也有音效的程式碼:

#include <windows.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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);

}

void mouse(int buttom, int state, int x, int y)

{

    if(state==GLUT_DOWN) PlaySound("shot.wav", NULL, SND_ASYNC);

}

int main(int argc, char**argv)

{

    mp3.Load("music.mp3");

    mp3.Play();

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

這個程式碼可以讓滑鼠左中右鍵分別有不同音效

#include <windows.h>

#include <GL/glut.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

CMP3_MCI shot1,shot2,shot3;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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);

}

void mouse(int button, int state, int x, int y)

{

    if(state==GLUT_DOWN&&button==GLUT_LEFT_BUTTON) shot1.Play();

    if(state==GLUT_DOWN&&button==GLUT_MIDDLE_BUTTON) shot2.Play();

    if(state==GLUT_DOWN&&button==GLUT_RIGHT_BUTTON) shot3.Play();

}

int main(int argc, char**argv)

{

    shot1.Load("1.wav"); shot2.Load("2.mav"); shot3.Load("3.wav");

    mp3.Load("music.mp3");

    mp3.Play();

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

opencv

 

一開始上課老師在複習之前教過的用opencv開啟圖檔。

今天教怎麼做背景，用id1、id2讓程式可以讀到兩張圖片。

程式碼:

#include <opencv/highgui.h>

#include <opencv/cv.h>

#include <GL/glut.h>

GLuint id1, id2;

int myTexture(char*filename)

{

    IplImage * img = cvLoadImage(filename);

    cvCvtColor(img,img, CV_BGR2RGB);

    glEnable(GL_TEXTURE_2D);

    GLuint id;

    glGenTextures(1, &id);

    glBindTexture(GL_TEXTURE_2D, id);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);

    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);

    return id;

    }

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glBindTexture(GL_TEXTURE_2D, id1);

    glutSolidTeapot(0.3);

    glBindTexture(GL_TEXTURE_2D,id2);

    glBegin(GL_POLYGON);

        glTexCoord2f( 0, 0 ); glVertex2f( -1, -1 );

        glTexCoord2f( 0, 1 ); glVertex2f( -1, +1 );

        glTexCoord2f( 1, 1 ); glVertex2f( +1, +1 );

        glTexCoord2f( 1, 0 ); glVertex2f( +1, -1 );

    glEnd();

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160661");

    glutDisplayFunc(display);

    id1=myTexture("star.jpg");

    id2=myTexture("bg.jpg");

    glEnable(GL_DEPTH_TEST);

    glutMainLoop();

}

最後一節課教打光，新增了幾行有關光的程式碼，

在const GLfloat light_position[] = { 2.0f, 5.0f, -5.0f, 0.0f };改變z的光源。

   glEnable(GL_DEPTH_TEST);這行程式碼是打開深度偵測，可以讓茶壺變立體。

最終程式碼:

#include <opencv/highgui.h>

#include <opencv/cv.h>

#include <GL/glut.h>

GLuint id1, id2;

int myTexture(char*filename)

{

    IplImage * img = cvLoadImage(filename);

    cvCvtColor(img,img, CV_BGR2RGB);

    glEnable(GL_TEXTURE_2D);

    GLuint id;

    glGenTextures(1, &id);

    glBindTexture(GL_TEXTURE_2D, id);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);

    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);

    return id;

    }

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glBindTexture(GL_TEXTURE_2D, id1);

    glutSolidTeapot(0.3);

    glBindTexture(GL_TEXTURE_2D,id2);

    glBegin(GL_POLYGON);

        glTexCoord2f( 0, 0 ); glVertex2f( -1, -1 );

        glTexCoord2f( 0, 1 ); glVertex2f( -1, +1 );

        glTexCoord2f( 1, 1 ); glVertex2f( +1, +1 );

        glTexCoord2f( 1, 0 ); glVertex2f( +1, -1 );

    glEnd();

    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 mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat high_shininess[] = { 100.0f };

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160661");

    glutDisplayFunc(display);

    id1=myTexture("star.jpg");

    id2=myTexture("bg.jpg");

    glEnable(GL_DEPTH_TEST);

    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);

    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();

}

openCV

小葉老師今天教我們用openCV

到小葉老師的網站下載windows跟data，解壓縮後把data放到windows檔案裡面

codeblocks裡面的setting點進compiler裡進行設定

Search directories裡加入

compiler: C:\OpenCV2.1\include

Linker: C:\OpenCV2.1\lib

在linker settings裡加入

cv210

cxcore210

highgui210

將glut打開，照片存在glut裡的lib檔案

程式碼:

#include <openCV/highgui.h>

int main()

{

    IplImage * img = cvLoadImage("wink.jpg");

    cvShowImage("photo", img);

    cvWaitKey(0);

}

cvWaitKey(0);讓程式可以跑很久

把圖放到茶壺上面

程式碼:

#include <opencv/highgui.h>

 ///使用 OpenCV 2.1 比較簡單, 只要用 High GUI 即可

#include <opencv/cv.h>

#include <GL/glut.h>

void init()

{

    IplImage * img = cvLoadImage("wink.jpg"); 

///OpenCV讀圖

    cvCvtColor(img,img, CV_BGR2RGB);

 ///OpenCV轉色彩 (需要cv.h)

    glEnable(GL_TEXTURE_2D); 

///1. 開啟貼圖功能

    GLuint id;

 ///準備一個 unsigned int 整數, 叫 貼圖ID

    glGenTextures(1, &id);

 /// 產生Generate 貼圖ID

    glBindTexture(GL_TEXTURE_2D, id);

 ///綁定bind 貼圖ID

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); 

/// 貼圖參數, 超過包裝的範圖T, 就重覆貼圖

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); 

/// 貼圖參數, 超過包裝的範圖S, 就重覆貼圖

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);

 /// 貼圖參數, 放大時的內插, 用最近點

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); 

/// 貼圖參數, 縮小時的內插, 用最近點

    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);

}  

 ///最後一行最難/最重要, 所貼圖影像的資料都設定好
