Week 03 楊淳安

作業一:

到網址:jsyeh.org/3dcg10 下載[data] [win32] [glut32.dll]

解壓縮後開啟shapes
右邊點選右鍵可更改圖案


右邊可調整點的位置和顏色

作業二:

程式碼

#include<GL/glut.h>  //標頭檔

void display()

{

    glBegin(GL_POLYGON);

       glColor3f(1,1,0);//顏色

       glVertex3f(0.0,0.0,0.0);

       glVertex3f(1.0,0.0,0.0);

       glVertex3f(1.0,1.0,0.0);

     glEnd();

   //glutSolidTeapot(0.3);

     glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc, argv);  //引入程式

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);  //雙視窗

    glutCreateWindow("hello 3D");  //視窗名稱

    glutDisplayFunc(display);  //展示

    glutMainLoop();

}

作業三:

用小畫家幫忙查作標

作業四:

利用mosue點座標 印出程式碼

程式碼:

#include <Gl/glut.h>

#include <stdio.h>

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

{

    if(state==GLUT_DOWN)

        printf("glVertex3f((%d-150)/150.0 ,-(%d-150)/150.0, 0.0);\n", x, y);

}

void display()

{

    glClearColor(152/255.0, 100/255.0, 222/255.0, 1);

    glClear(GL_COLOR_BUFFER_BIT);

    glBegin(GL_POLYGON);

        glColor3ub(192, 215, 107);

        glVertex3f((95-100)/100.0,-(49-100)/100.0, 0.0);

        glVertex3f((17-100)/100.0,-(106-100)/100.0, 0.0);

        glVertex3f((93-100)/100.0,-(165-100)/100.0, 0.0);

        glVertex3f((174-100)/100.0,-(103-100)/100.0, 0.0);

    glEnd();

    glBegin(GL_POLYGON);

glVertex3f((38-150)/150.0 ,-(22-150)/150.0, 0.0);

glVertex3f((41-150)/150.0 ,-(57-150)/150.0, 0.0);

glVertex3f((110-150)/150.0 ,-(63-150)/150.0, 0.0);

glVertex3f((114-150)/150.0 ,-(27-150)/150.0, 0.0);

    glEnd();

    glutSwapBuffers();

}

int main(int argc, char **argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("hello");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}
