2021電腦圖學二乙: 想睡覺week12

第一節課老師給我們一個之前的軟體可以把3d模型弄出來存成CPP檔

一萬多行跟鬼一樣

再來開codeblocks 開openGL專案把剛剛的cpp跟bmp檔丟進去

然後打開

要加這兩行反白的之後有問題的都註解掉就好

成品

會一直轉+抖喔
第二節課把茶壺打光

程式碼:

#include <windows.h>

#include <GL/glut.h>///(0)使用GLUT外掛

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);///清空

glutSolidTeapot(0.3);///實心茶壺

glutSwapBuffers();///交換兩倍的buffers

}

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_ambient[] = { 0.7f, 0.7f, 0.7f, 1.0f };

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 };

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);

}

void mouse(int button,int state,int x,int y)

{

if(state==GLUT_DOWN)PlaySound("shot.wav",NULL,SND_ASYNC);

}

int main(int argc, char ** argv)///以前是int main()

{

glutInit(&argc, argv);///(1)GLUT初始設定

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);///(2)顯示模式

glutCreateWindow("08160855_YEE");///開窗

glEnable(GL_DEPTH_TEST);

glDepthFunc(GL_LESS);

glEnable(GL_LIGHT0);

glEnable(GL_NORMALIZE);

glEnable(GL_COLOR_MATERIAL);

glEnable(GL_LIGHTING);

glLightfv(GL_LIGHT0, GL_AMBIENT, light_ambient);

glLightfv(GL_LIGHT0, GL_DIFFUSE, light_diffuse);

glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);

glLightfv(GL_LIGHT0, GL_POSITION, light_position);

glMaterialfv(GL_FRONT, GL_AMBIENT, mat_ambient);

glMaterialfv(GL_FRONT, GL_DIFFUSE, mat_diffuse);

glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular);

glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

glutDisplayFunc(display);///(4)等一下要顯示的函式

glutKeyboardFunc(keyboard);

glutMouseFunc(mouse);

glutMainLoop();///(5)主要迴圈

}

綠色的是打光

再來設定貼圖要先安裝OpenCV 然後重開codeblocks

然後setting-compiler設定路徑

圖又丟不上來了反正有三個要弄的

嘛~加油

然後把檔案路徑改成一個.

然後把glut裡的dll檔丟到專案裡讓程式可以打開就好

再來弄貼圖

程式碼:

#include <windows.h>

#include <GL/glut.h>///(0)使用GLUT外掛

#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;

}
