呵 長大了-week10

 今日第一個程式 (先把模型、glm.h、glm.c丟進專案)

#include <stdio.h>

#include "glm.h"

GLMmodel * pmodel = NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    if(pmodel==NULL){

        pmodel = glmReadOBJ("Al.obj");

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel ,90);

    }

    glmDraw(pmodel , GLM_MATERIAL);

    ///glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutMainLoop();

}

今日第二個程式(鋼蛋模型)

先設定 打開 Open CV   

Settings=>Compiler=>Search directories=>Add => C:\OpenCV2.1\include、 C:\OpenCV2.1\lib

換Linker setting Add => cv210、cxcore210、highgui210

#include <stdio.h>

#include "glm.h" ///下載 source.zip有glm.h放在week10_glm目錄裡

///glm.c改檔名成glm.cpp放在week10_glm目錄裡

///把glm.cpp加到專案裡

///把模型(ex. Al.obj A.mtl)複製到工作目錄

///再把Gundam.obg Gundam.mtl Diffuse.jpg放到工作目錄

#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
