課堂作業1

從網址下載: sorce , date , win32 ,glut32.dll ( jsyeh.org/3dcg10 )

解壓縮win32

把 data 打開，將裡面的資料夾複製到上面解壓縮後的window32資料夾

再將 glut32.dll 移至window32資料夾

執行Shapes

課堂作業2

寫個三角形

code:

#include <GL/glut.h>

void display()

{

    glClearColor(10, 0.5, 1, 1);

    glClear(GL_COLOR_BUFFER_BIT);

    glBegin(GL_POLYGON);

        glColor3f(1, 0, 0);  glVertex3f(-1.0, 0.0, 0.0);

        glColor3f(0, 1, 0);  glVertex3f(1.0, -1.0, 0.0);

        glColor3f(0, 0, 1);  glVertex3f(1.0, 1.0, 0.0);

    glEnd();

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DEPTH | GLUT_DEPTH);

    glutCreateWindow("hello3D");

    glutDisplayFunc(display);

    glutMainLoop();

}

課堂作業3

小畫家幫你查color,座標

code:

#include <GL/glut.h>

void display()

{

    glClearColor(10, 0.5, 1, 1);

    glClear(GL_COLOR_BUFFER_BIT);

    glBegin(GL_POLYGON);

        glColor3f(1, 0, 0);

        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();

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DEPTH | GLUT_DEPTH);

    glutCreateWindow("hello3D");

    glutDisplayFunc(display);

    glutMainLoop();

}

課堂作業4

用mouse點座標,印出程式碼

code:

#include <GL/glut.h>

#include <stdio.h>

void mouse(int botton, 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(10, 0.5, 1, 1);

    glClear(GL_COLOR_BUFFER_BIT);

    glBegin(GL_POLYGON);

        glColor3f(1, 0, 0);

        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);

        glColor3f(1, 0, 0);

        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();

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DEPTH | GLUT_DEPTH);

    glutCreateWindow("hello3D");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}
