把茶壺的程式碼丟上去

#include <GL/glut.h>

 void display()

 {

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,0);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

 }

 int main(int argc, char *argv[])//main()主函式 進階版

 {

    glutInit(&argc,argv);//把參數送給glutInit初始化

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);//雙緩衝區+3D深度功能

    glutCreateWindow("第02週的程式喔!!");//開GLUT視窗

    glutDisplayFunc(display);//顯示用的函式

    glutMainLoop();

 }

=========================================================================

把茶壺改到右上角

程式碼:

 #include <GL/glut.h>

 void display()

 {

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

    glTranslatef(0.5,0.5,0);

    glColor3f(1,1,0);

    glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

 }

 int main(int argc, char *argv[])//main()主函式 進階版

 {

    glutInit(&argc,argv);//把參數送給glutInit初始化

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);//雙緩衝區+3D深度功能

    glutCreateWindow("第02週的程式喔!!");//開GLUT視窗

    glutDisplayFunc(display);//顯示用的函式

    glutMainLoop();

 }

=========================================================================

把茶壺變成四個

程式碼:

#include <GL/glut.h>

 void myTeapot(float x,float y)

 {

    glPushMatrix();

    glTranslatef(x,y,0);

    glColor3f(1,1,0);

    glutSolidTeapot(0.3);

    glPopMatrix();

 }

 void display()

 {

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    myTeapot(0.5,0.5);

    myTeapot(0.5,-0.5);

    myTeapot(-0.5,-0.5);

    myTeapot(-0.5,0.5);

    glutSwapBuffers();

 }

 int main(int argc, char *argv[])//main()主函式 進階版

 {

    glutInit(&argc,argv);//把參數送給glutInit初始化

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);//雙緩衝區+3D深度功能

    glutCreateWindow("第02週的程式喔!!");//開GLUT視窗

    glutDisplayFunc(display);//顯示用的函式

    glutMainLoop();

 }

可以用滑鼠去移動他

程式碼:

#include <Gl/glut.h>

float mouseX=0, mouseY=0;

void myTeapot(float x,float y)

{

    glPushMatrix();

    glTranslatef(x,y,0);

    glColor3f(1,1,0);

    glutSolidTeapot(0.3);

    glPopMatrix();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    myTeapot( (mouseX-150)/150.0,-(mouseY-150)/150.0);

    glutSwapBuffers();

}

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

{

    mouseX=x; mouseY=y;

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week03 移動");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}

=========================================================================

week03_mouse_help_hw2

程式碼:

#include <GL/glut.h>

#include <Stdio.h>

float mouseX=0 , mouseY=0;

void myTeapot(float x,float y)

{

    glPushMatrix();

    glTranslatef(x,y,0);

    glColor3f(1,1,0);

    glutSolidTeapot(0.1);

    glPopMatrix();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    myTeapot( (mouseX-150)/150.0,-(mouseY-150)/150.0);

    glutSwapBuffers();

}

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

{

    printf("%d %d %d %d\n",button,state,x,y);

    mouseX=x; mouseY=y;

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week03 移動");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();
