(1)

1-1.開CodeBlocks

1-2.File - New - Project ,開GLUT

1-3.設定settings/Compiler

         (1)Search diedctories

           <1>Compiler

                 Add - C: \ OpenCV2.1 \ include

           <2>Linker

                 Add - C: \ OpenCV2.1 \ lib

        (2)Linker settings

             Add - cv210 & cxcore210 & highgui210

1-4.把gundam/data放到工作執行目錄freeglut/bin

1-5.顯示圖

#include <opencv/highgui.h>

int main()

{

    IplImage*img =cvLoadImage("data/Diffuse.jpg");

    cvShowImage("week11",img);

    cvWaitKey(0);

}

(2)

2-1.貼上周程式(貼圖在茶壺上)

#include <opencv/highgui.h>

#include <opencv/cv.h>

#include <GL/glut.h>

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);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc,char** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11 gundam");

    glutDisplayFunc(display);

    myTexture("data/Diffuse.jpg");

    glutMainLoop();

}

2-2.把 glm.c & glm.h & transformation.c 加到 week11_gundam ，把glm.c改附檔名

       -->glm.cpp

2-3.加程式碼 codeblocks / week11_gundam 按右鍵 add file 加glm.cpp

2-4.寫程式碼

#include <opencv/highgui.h>

#include <opencv/cv.h>

#include <GL/glut.h>

#include "glm.h"///在專業目錄找

GLMmodel * pmodel = NULL ;///指標，指到模型，是空指標

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);

    if( pmodel == NULL){

        pmodel=glmReadOBJ("data/Gundam.obj") ; ///讀模型

        glmUnitize(pmodel) ; ///換成Unit單位大小

        glmFacetNormals(pmodel) ; ///重新計算法向量

        glmVertexNormals(pmodel,90) ; ///重新計算模型頂點的法向量

    }

    glmDraw(pmodel,GLM_TEXTURE) ; ///模型畫貼圖

    glutSwapBuffers () ;

}

int main(int argc,char** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11 gundam");

    glutDisplayFunc(display);

    myTexture("data/Diffuse.jpg");

    glutMainLoop();

}

2-5.圖片方向不對，用小畫家把Diffuse.jpg垂直翻轉

2-6.加3D，旋轉

#include <opencv/highgui.h>

#include <opencv/cv.h>

#include <GL/glut.h>

#include "glm.h"///在專業目錄找

GLMmodel * pmodel = NULL ;///指標，指到模型，是空指標

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;

}

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    if( pmodel == NULL){

        pmodel=glmReadOBJ("data/Gundam.obj");///讀模型

        glmUnitize(pmodel);///換成Unit單位大小

        glmFacetNormals(pmodel);///重新計算模型面的法向量

        glmVertexNormals(pmodel,90);///重新計算模型頂點的法向量

    }

    glPushMatrix();

        glRotatef(angle,0,1,0);

        glmDraw(pmodel,GLM_TEXTURE);///模型畫貼圖

    glPopMatrix();

    glutSwapBuffers();

    angle+=0.8;

}

int main(int argc,char** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11 gundam");

    glutIdleFunc(display);

    glutDisplayFunc(display);

    myTexture("data/Diffuse.jpg");

    glEnable(GL_DEPTH_TEST);

    glutMainLoop();

}

3-1.開新的 GLUT/week11_TRT

3-2.寫程式 模擬手臂轉動

#include <GL/glut.h>

void hand(){

    glColor3f(0,1,0);

    glutSolidTeapot(0.2);

}

void body(){

    glColor3f(1,1,0);

    glutSolidTeapot(0.3);

}

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    body();

    glPushMatrix();

        glTranslated(0.5,0.2,0);

        glRotatef(angle,0,0,1);

        glTranslated(0.3,0,0);

        hand();

    glPopMatrix();

    glutSwapBuffers();

    angle+=0.3;

}

int main(int argc,char** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11 TRT");

    glutIdleFunc(display);

    glutDisplayFunc(display);

    glutMainLoop();

}
