我們來計時吧(唐突)(?)

總而言之，今天的主題是「計時器(Timer)」！一個相當重要的東西。總之我們先開始吧～～

首先我們要下載fr......

接著我們開始來做吧～～

首先，這次的程式碼如下......

#include <GL/glut.h>

#include <mmsystem.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSwapBuffers();

}

void timer(int t)///NOW (2)

{

    glutTimerFunc(1000, timer, 0);

    PlaySoundA("Illuminati Confirmed.wav", NULL, SND_ASYNC);

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(900,900);

    glutCreateWindow("week14 timer");

    glutDisplayFunc(display);

    glutTimerFunc(1000, timer, 0);

    glutMainLoop();

}

來播播看吧～～

真是奇妙的音樂......？

*Illuminati Confirmed Sound*

反正成功了，阿哈哈......我們繼續吧～～

接著我們讓它能夠一直重複地讓茶壺動作吧

這次的程式碼如下......

#include <GL/glut.h>

#include <mmsystem.h>///NOW (0)發聲音

#include <stdio.h>///NOW3 for printf()

float angle=0;///NOW4

float nowX=0;///NOW5

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();///NOW4

        ///glRotatef(angle, 0, 0, 1);///NOW4

        glTranslatef(nowX, 0, 0);///NOW5

        glutSolidTeapot( 0.3 );///NOW4

    glPopMatrix();///NOW4

    glutSwapBuffers();

}

void timer(int t)///NOW (2)

{/// 1000 ms = 1秒,   33ms = 0.033秒 => 33*30=1000,  30fps

    glutTimerFunc(33, timer, t+1);///NOW4 ///NOW3 一起床,馬上撥下一個鬧鐘, 時間才會準

    printf("現在的 timer(t)的t是: %d\n", t);///NOW3

    float alpha = (t%30) / 30.0;///變成 alpha: 0.0 ~ 1.0  ///NOW5

    nowX = alpha*1.0 + (1-alpha)* -1.0;///NOW5

    glutPostRedisplay();///NOW4 要更新畫面

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(500,500);///大一點

    glutCreateWindow("week14 timer");

    glutDisplayFunc(display);

    glutTimerFunc(1000, timer, 0);///NOW (1)

    glutMainLoop();

}

來播播看吧

可以播放！而且計時器也確實有在運作！

接著就來更進一步來嘗試吧

這是最後的結果......

成果為......

幫我稱10秒!_week14

第一節課是計時器的練習

 glutTimerFunc(1000, timer, 0);

 1000為1秒  後面的0是一個變數

下列程式能讓茶壺不停的旋轉

#include <GL/glut.h> #include <mmsystem.h>///NOW (0)發聲音 #include <stdio.h>///NOW3 for printf() float angle=0;///NOW4 void display() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix();///NOW4 glRotatef(angle, 0, 0, 1);///NOW4 glutSolidTeapot( 0.3 );///NOW4 glPopMatrix();///NOW4 glutSwapBuffers(); } void timer(int t)///NOW (2) { glutTimerFunc(30, timer, t+1);///NOW4 ///NOW3 一起床,馬上撥下一個鬧鐘, 時間才會準 printf("現在的 timer(t)的t是: %d\n", t);///NOW3 angle = t;///NOW4 glutPostRedisplay();///NOW4 要更新畫面 } int main(int argc, char**argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH); glutInitWindowSize(500,500);///大一點 glutCreateWindow("week14 timer"); glutDisplayFunc(display); glutTimerFunc(1000, timer, 0);///NOW (1) glutMainLoop(); }

第二節課在教內差公式

設定 alpha值 float alpha = (t%30)/30.0; ///變成alpha:0.0~1.0
內差公式:nowX = alpha*1.0+(1-alpha)* -1.0;
可以利用內差公式來做動畫
    glPushMatrix();///NOW4
        glTranslatef(nowX, 0, 0);///NOW4
        glutSolidTeapot( 0.3 );///NOW4
    glPopMatrix();///NOW4

如何把檔案帶到其他地方開起來

把cbp檔案用notepad++打開

並且把<Option working_dir="." /> 連結位子處改成.

和<Add directory="C:/Users/user/Desktop/freeglut/include" /> 改成自己名稱的位子

最後下面這是能用計時器+內差公式做出動畫的程式
