獻祭肝臟的電腦圖學課堂筆記_week05

 1.電腦圖學之父Ivan Sutherland

2.jsyeh.org/3dcg10下載data.zip,windows

3.開啟codeblocks

貼上之前的程式碼

並且稍作修改，加上keyboard函式

按下鍵盤任一按鍵後，會顯示你按下的鍵和目前滑鼠所在的位置座標

#include <GL/glut.h>

#include <stdio.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,0);///黃色的

    glutSolidTeapot(0.3);///茶壺

    glutSwapBuffers();

}

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

{

    printf("你按下了 %c 在 %d %d 座標\n",key,x,y);

}

int main(int argc,char** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week05");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

然後我們接續剛剛的程式碼

改成keyboard+mouse+motion

#include <GL/glut.h>

#include <stdio.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,0);///黃色的

    glutSolidTeapot(0.3);///茶壺

    glutSwapBuffers();

}

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

{

}

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

{

}

void motion(int x,int y)

{

}

int main(int argc,char** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week05");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutMainLoop();

}
