1. week15-1_PlaySound
(1)安裝freeglut
(2)打開新專案，命名為：week15-1_PlaySound
(3)第一行新增：#include <windows.h>，把 PlaySound("C:/mykbeat.wav",NULL,SND_ASYNC); 放在int main裡面
(4)把 mykbeat.wav 放在C槽裡，播放後就有聲音了
(5)把 Do.wav ~ Sol.wav 放入C槽中，加上
PlaySound("C:/Re.wav",NULL,SND_SYNC);
PlaySound("C:/Mi.wav",NULL,SND_SYNC);
PlaySound("C:/Fa.wav",NULL,SND_SYNC);
PlaySound("C:/Sol.wav",NULL,SND_SYNC);
##ASYNC ： 不同步/不等待
##SYNC ： 同步/等待
(6)播放後就會先從Do一個個播到Sol，最後再播mykbeat
2. week15-2_PlaySound_empty
(1)打開新專案，命名為：week15-2_PlaySound_empty
(2)把所有程式碼刪掉，加上程式碼：
int main()
{
PlaySound("C:/Do.wav",NULL,SND_SYNC);
}
(3)執行後就是簡單的播音樂的程式了
3. 回到 week15-1_PlaySound
##把 projects 的 properties 內的 Build Targets 內的 Execution working dir 改成 .
##然後把freeglut資料夾內的bin裡的 freeglut.dll 複製道專案資料夾中，這樣音檔路徑就不用打了
(1)在 static void key 中新增：
PlaySound("Do.wav",NULL,SND_ASYNC);
break;
case '2':
PlaySound("Re.wav",NULL,SND_ASYNC);
break;
case '3':
PlaySound("Mi.wav",NULL,SND_ASYNC);
break;
這樣就能用鍵盤彈音符了
4. week15-3_CMP3_MCI
(1)打開新專案，命名為：week15-3_CMP3_MCI
(2)把 CMP3_MCI.h 、 sone.mp3 和 freeglut.dll 放進專案目錄中，把Execution working dir 改成 .
(3)在第一行加上程式碼：
CMP3_MCI myMP3;
在int main中加入：
myMP3.Play();
(4)播放後就有音效了
5. week15-4_mouse_motion_translate_rotate
(1)打開新專案，命名為：week15-4_mouse_motion_translate_rotate
(2)把所有程式碼刪掉，加上11行程式碼：
#include <GL/glut.h>
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(0.3);
glutSwapBuffers();
}
int main(int argc, char*argv[])
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week05");
glutDisplayFunc(display);
glutMainLoop();
}
(3)增加滑鼠移動的程式
float angleX[10]={}, angleY[10]={};
float teapotX=0, teapotY=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glTranslatef(teapotX, teapotY, 0);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void mouse(int button, int state, int x, int y)
{
oldX = x;
oldY = y;
}
void motion(int x, int y)
{
teapotX += (x - oldX)/150.0;
teapotY -= (y - oldY)/150.0;
}
int main(int argc, char*argv[])
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week15");
glutDisplayFunc(display);
}
(4)加上茶壺移動座標的程式
#include <stdio.h>
float angleX[10]={}, angleY[10]={};
float teapotX=0, teapotY=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glTranslatef(teapotX, teapotY, 0);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int oldX = 0, oldY = 0;
void mouse(int button, int state, int x, int y)
{
oldX = x;
oldY = y;
}
void motion(int x, int y)
{
teapotX += (x - oldX)/150.0;
teapotY -= (y - oldY)/150.0;
printf("glTranslatef(%.3f, %.3f, 0);\n", teapotX, teapotY);
oldX = x;
oldY = y;
glutPostRedisplay();
}
int main(int argc, char*argv[])
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week15");
glutDisplayFunc(display);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutMainLoop();
}
(5)畫出中心點，能藉由中心點找出TRT的旋轉移動位置
#include <stdio.h>
float angleX[10]={}, angleY[10]={};
float teapotX=0, teapotY=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidSphere(0.02, 30, 30);
glPushMatrix();
glTranslatef(teapotX, teapotY, 0);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int oldX = 0, oldY = 0;
void mouse(int button, int state, int x, int y)
{
oldX = x;
oldY = y;
}
void motion(int x, int y)
{
teapotX += (x - oldX)/150.0;
teapotY -= (y - oldY)/150.0;
printf("glTranslatef(%.3f, %.3f, 0);\n", teapotX, teapotY);
oldX = x;
oldY = y;
glutPostRedisplay();
}
int main(int argc, char*argv[])
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week15");
glutDisplayFunc(display);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutMainLoop();
}
(6)加上TRT程式，並註解掉一些不需要的程式
#include <stdio.h>
float angleX[10]={}, angleY[10]={};
float teapotX=0, teapotY=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidSphere(0.02, 30, 30);
glPushMatrix();
///glTranslatef(teapotX, teapotY, 0);
glRotatef(angleX[0], 0, 0, 1);
glTranslatef(-0.500, -0.127, 0);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int oldX = 0, oldY = 0;
void mouse(int button, int state, int x, int y)
{
oldX = x;
oldY = y;
}
void motion(int x, int y)
{
///teapotX += (x - oldX)/150.0;
///teapotY -= (y - oldY)/150.0;
///printf("glTranslatef(%.3f, %.3f, 0);\n", teapotX, teapotY);
angleX[0] += (x-oldX);
oldX = x;
oldY = y;
glutPostRedisplay();
}
int main(int argc, char*argv[])
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week15");
glutDisplayFunc(display);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutMainLoop();
}
