1.檔案存讀，在執行目錄中建立文字檔，裡面寫要讀取的資料

        fout = fopen("檔名.txt","w+");

        printf (      "Hello World\n");

       fprintf ( fout,"Hello World\n");

    }

2.更改專案目錄，將freeglut.dll放到week15專案裡，修改專案中的week15-file.cbp，更改路徑

電腦圖學week13

電腦圖學Week13 (第一次線上上課)

老師目標

1. 主題: 做出機器人(有關節)

2. 複習: 貼圖

3. 複習: 改專案的工作目錄

4. 複習: glm模型

5. 複習: 旋轉

6. 複習: T-R-T旋轉

先做設定 

                freeglut，OpenCV 設定 C:\OpenCV2.1\include C:\OpenCV2.1\lib

                                                        cv210 cxcore210 highgui210

                開啟專案 Fiile-New-Project, GLUT專案

                放入貼圖範例程式，把圖檔放在 freeglut/bin  

                讓目錄正確 改到專案目錄week13

                把 freeglut\bin 的 freeglut.dll 移到專案目錄 week13

                把圖片移到專案目錄 week13

                用 Notepad++把 week13.cbp 打開

                兩個working_dir 改成 "." 

                CodeBlocks Reload

設定完成，實作

#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>

GLuint id1, id2; ///TODO:增加2個 貼圖ID

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;

}

電腦圖學week12

1.安裝3D Exploration

2.另存cpp Open GL檔案

3.CodeBlocks開OpenGL方案，選擇Remove file from project，Add files gundam_3dexp.cpp

4.加入兩行程式碼 #define GL_BGRA_EXT 0x80E1

                                  #define GL_BGR_EXT 0x80E0

5.註解掉兩行程式碼 //(LPLOGPALETTE) lpPalette = (LPLOGPALETTE)HeapAlloc (hHeap, 0,

                                      //sizeof (LOGPALETTE) + (nColors * sizeof (PALETTEENTRY)));

6.移除旋轉與放大縮小 加入 glRotatef(nAngle,0,1,0);

                                                    glScalef(3,3,3);

7.1 HW4教學:保留打光程式碼

#include <GL/glut.h>

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

///下面是從 GLUT專案main.cpp剪貼來的

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_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);

    ///下面是從 GLUT專案main.cpp剪貼來的

    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);

    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMainLoop();

}

7.2 修改執行目錄，把freeglut.dll移到week12_hw4

電腦圖學week11

File-New-Project GLUT專案  設定 libglut32

source.zip 裡的檔案 ( glm.h , glm.c , transformation.c ) 加進week11_model資料夾

glm.h 放同目錄 (桌面的week11_model資料夾)

glm.c 改檔名成 glm.cpp 並加入專案  Project, Add files, glm.cpp加入

transformation.c 的程式碼放到 main.cpp (原本的全部刪掉)

把data資料夾放入 C:\Users\Administrator\Desktop\freeglut\bin 

改寫程式碼 做出自己的3D模型

#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);
