利用CodeBlocks做出補間動畫〈alpha公式〉：
#include <GL/glut.h> #include <mmsystem.h>///聲音 #include <stdio.h> float angle=0; float nowX=0; void display() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix(); //glRotatef(angle, 0, 0, 1); glTranslatef(nowX, 0, 0); glutSolidTeapot( 0.3 ); glPopMatrix(); glutSwapBuffers(); } void timer(int t) { glutTimerFunc(30, timer, t+1);///timer(重複播) printf("這是第%d次\n", t); float alpha = (t%30)/30.0; nowX=alpha*1.0 + (1-alpha)*-1.0; PlaySoundA("thwap.wav", NULL, SND_ASYNC);///不同步 //angle = t; glutPostRedisplay();///更新畫面 } int main(int argc, char**argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH); glutInitWindowSize(500, 500); glutCreateWindow("timer"); glutDisplayFunc(display); glutTimerFunc(1000, timer, 0);///timer glutMainLoop(); }
