week10 UC

 step01-1

先去把github的整個倉庫備份下來之後再Codeblocks裡開起week08-2_glm_model_Texture.cbp

複製到main

#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;

}

#include <GL/glut.h>

#include "glm.h"

GLMmodel * pmodel = NULL;

float angle=0;

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();

        glRotatef(angle,0,1,0);

        glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL | GLM_TEXTURE);

    glPopMatrix();

    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();

}

還要下載OpenCV並設定三步驟

將CodeBlocks重開後把第八周的程式碼，glm.cpp，glm.h都丟到第十周

在第十周右鍵 Add files添加glm.cpp

要記的翻轉圖片(開啟小畫家照片垂直翻轉)

step03-1 儲存修改位置

把剛剛的檔案轉過來
