 WEEK10

week10-0

先考期中考11行程式碼

week10-1 glm gundam

先把 opencv 跟 freeglut用好

開啟新的freeglut檔案然後命名

把Computer Graphics (jsyeh.org)的source下載解壓縮然後把glm.c跟glm.h拉進桌面的week10-1檔案裡

再把老師給的鋼蛋三張圖片放進桌面的freeglut/bin裡,把Diffuse圖片用小畫家打開然後垂直翻轉再打上程式,執行就可以跑出鋼蛋模型了

#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>

int myTexture(char * filename)

{

    IplImage * img = cvLoadImage(filename); ///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);

    return id;

}

#include <GL/glut.h>

#include "glm.h"///把source.zip裡的glm.h放在同目錄

float angle=0;

GLMmodel * pmodel =NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    if(pmodel==NULL){

        pmodel = glmReadOBJ("Gundam.obj");

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel, 90);

    }

    glPushMatrix();

    glRotated(angle, 0, 1, 0);

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL | GLM_TEXTURE);

    glPopMatrix();

    ///glutSolidTeapot( 0.3 );

    angle++;

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    myTexture("Diffuse.jpg");

    glEnable(GL_DEPTH_TEST);

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}

到桌面week10-1目錄裡把week10-1 glm gundamCBD檔用Notepad++開啟然後更改東西,再把freeglut/bin裡的四個檔案複製貼上到week10-1裡,執行目錄就會更改了,成功的話鋼蛋就可以執行出來
