1. 小考: T-R-T觀念

glPushMatrix();
      glTranslatef(+0.1, +0.5, 0);
      glRotatef(+30, 0, 0, 1);
      glTranslatef(+0.3, 0, 0);  /// 看圖的位置給予反方向(負號)
      drawArm(); ///看圖給的函數
glPopMatrix();

2. MP3播放

#include "CMP3_MCI.h" /// Mp3的外掛
CMP3_MCI myMP3;
int a;
int main(int argc, char *argv[])
{
    myMP3.Load("Ed.mp3");
    myMP3.Play();

3.計時器Timer

#include <mmsystem.h>

void timer(int t) ///計時器函數
{
    glutTimerFunc(1000, timer, t+1);
    PlaySound("Do.wav", NULL, SND_ASYNC);
}
int main(int argc, char *argv[])
{
    glutTimerFunc(5000, timer, 0);///呼叫計時器函數




4.線性內插動畫
-Excel



5. 茶壺自動旋轉

#include <GL/glut.h>
#include <stdio.h>
float angle = 0, oldAngle=0, newAngle= 90;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glRotated(angle, 0,0,1);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glutSwapBuffers();
}

void timer(int t)
{
    glutTimerFunc(5, timer, t+1);
    float alpha = (t)/30.0;
    angle = newAngle * alpha + oldAngle*(1-alpha);
    glutPostRedisplay();
}
int main(int argc, char *argv[])
{
    glutInit(&argc, argv);
    glutInitWindowSize(640,480);
    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("GLUT Shapes");

    glutTimerFunc(0, timer, 0);///呼叫計時器
    glutDisplayFunc(display);
    glutMainLoop();
}
