1.期末作品示範
2.背景貼圖示範
3.打光,貼圖切換
4.讀檔內插示範
5.學期總複習

必須先下載OpenCV 2.1 並安裝到桌面
還需要cv210 / cxcore210 / highgui210 這三個檔案

void display()
{   
glEnable(GL_DEPTH_TEST); ///要啟動 Detph Test 深度值的測試,3D顯示才正確
    glClear(GL_COLOR_BUFFER_BIT  | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glBegin(GL_POLYGON);
            glTexCoord2f(0,0); glVertex3f(-1,+1,0);///前面是貼圖座標，後面是3D頂點
            glTexCoord2f(1,0); glVertex3f(+1,+1,0);
            glTexCoord2f(1,1); glVertex3f(+1,-1,0);
            glTexCoord2f(0,1); glVertex3f(-1,-1,0);
        glEnd();
    glPopMatrix();
    glFlush();
}

void myInit()
{
    quad = gluNewQuadric();
    id = myTexture("images.jpg");///id為貼圖，這樣就可以讀到貼圖的路徑

}




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;

week16 溫洺漢 上課筆記

內插公式加入

Timer函式

內插公式 =A2*90000+(1-A2)*30000

存檔須加的程式碼
#include <stdio.h>
printf("%c\n", key);
    if(key=='0') now=0;///今天簡化修改
    if(key=='1') now=1;///今天簡化修改
    if(key=='2') now=2;///今天簡化修改
    if(key=='3') now=3;///今天簡化修改
    if(key=='4') now=4;///今天簡化修改
    if(key=='5') now=5;///今天簡化修改
    if(key=='s' || key=='S'){
        if(fout==NULL){///寫檔案的第3行, 如果是空的,第一次寫檔
            fout=fopen("file.txt", "w+");///寫檔案的第4行, 真的去開檔案
            printf("現在我產生一個file.txt的檔案在目錄裡面哦\n");
        }
        fprintf(fout, "%.3f %.3f %.3f %.3f %.3f\n", angle[0],angle[1],angle[2],angle[3],angle[4]);///寫檔案的第5行
        printf("現在我把一些數字印到檔案裡面%.3f %.3f %.3f %.3f %.3f\n",
               angle[0],angle[1],angle[2],angle[3],angle[4]);
    }
}

week14 溫洺漢 上課筆記

計時器: 在main()
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);


void timer (int t)
{
glutTimerFunc(10,timer,++1);
angle++;
glutPostRedisplay();

改程式讓頭 身體 左右手一起旋轉

week13 溫洺漢 上課筆記

T-R-T小考練習
glPushMatrix();
glTranslatef(0.4,-1.0,0);
glRotatef(angle,0,0,1);
glTranslatef(0.2,-0.5,0);
drawLeg();
glPopMatrix();

最後執行就能找到放在C槽裡小畫家自己所畫的作品

到Linker Settings新增3個東西 cv210 ,cxcore210 ,highgui210

到Search directories裡的Linker add c:\opencv2.1\lib

新增貝殼專案File-New-Project，
然後成是開啟後全刪，再新增新的程式碼
#include <openCV/highgui.h>
int main()
{
    IplImage * img=cvLoadImage("C:/img.png");
    cvShowImage("a",img);
    cvWaitKey(0);
}
新增完後，右鍵點選專案Build Options，然後到Search directories裡的compiler add c:\opencv2.1\include

到openCV download 2.1下載檔案，並且開啟完成設定

設定以下東西

到google 3D Exploration下載1.81版本，並到jsyeh.org/3dcg10下載data資料夾然後用3D Exploration開啟

刪除原程式並加入soccerball程式



將下面這2行註解掉(LPLOGPALETTE) lpPalette = (LPLOGPALETTE)HeapAlloc (hHeap, 0,
            sizeof (LOGPALETTE) + (nColors * sizeof (PALETTEENTRY)));

File  Save-as，選擇cpp Open GL，並勾選Export Dialog，然後選Sample APP

將MP3放到這裡面來

加入以下程式\

#include "CMP3_MCI.h"

CMP3_MCI myMP3;    

myMP3.Load("C:\\Users\\user\\Desktop\\freeglut\\bin\\yukai.MP3");

    myMP3.Play();

加入以下程式 glutKeyboardFunc(keyboard);來製造出鋼琴的聲音

void keyboard(unsigned char key, int x, int y)

{

    if(key=='1') PlaySound("Do.wav",NULL,SND_ASYNC);

    if(key=='2') PlaySound("Re.wav",NULL,SND_ASYNC);

    if(key=='3') PlaySound("Mi.wav",NULL,SND_ASYNC);

    if(key=='4') PlaySound("Fa.wav",NULL,SND_ASYNC);

    if(key=='5') PlaySound("So.wav",NULL,SND_ASYNC);

}

茶壺打光的上課筆記

嘗試以上的各種函式

加入以下程式
float angle=0;
static void display(void)
{
    angle++;
    glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
       glTranslatef(0,0.6,0);
       glutSolidTeapot(0.3);
    glPopMatrix();
    glPushMatrix();
       glRotatef(angle,0,1,0);
       glutSolidTeapot(0.3);
      glPopMatrix();
      glutSwapBuffers();
}


這行程式glutIdleFunc(display);
加到這行程式 glutDisplayFunc(display);的前面
讓一個茶壺移動一個茶壺旋轉

把茶壺叫出來，把下面的程式碼加入
glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
       ///glTranslatef(x,y,z);
       ///glRotatef(angle,x,y,z);
      glutSolidTeapot(0.3);
      glPopMatrix();
      glutSwapBuffers();
　　　　

week06溫洺漢上課筆記

程式必須由下往上看，按右鍵切換成 swap translate/rotate，讓車子能同時放大縮小，又能同時移動然後同旋轉，像車子在繞場一圈


若沒有按右鍵切換成 swap translate/rotate，車子只能往右移，然後在移到的位置原地旋轉而已

glRotatef(90.0 ,0.00 ,1.00 ,0.00); 的Y軸若為1，旋轉90度時車頭朝右

glRotatef(90.0 ,1.00 ,1.00 ,0.00); 的X軸與Y軸若為1，旋轉90度時車頭朝右下(竹籤由左下插，東西會向右下旋轉)


glRotatef(90.0 ,0.00 ,-1.00 ,0.00); 的Y軸若為-1，旋轉90度時車頭朝左

week4課堂作業 溫洺漢

將translate的地方改成scale使茶壺任意縮放
glScalef(mouseX,mouseY,0);

使用茶壺的程式，加入gltranslatef(0.5,0,0)讓茶壺能向右移動

延續上圖的程式加入float mouseX=0, mouseY=0;在第二行


在int main前加入下面這幾行然後把(x-150)/150.0;
然後y的值一樣照上面寫但前面須加負號
把motion的註解顯示出來


void motion(int x, int y)
     {
         mouseX = (x-150)/150.0;
         mouseY = -(y-150)/150.0;
         glutPostRedisplay();
     }
