旋轉他 增加(紅色)
#include <GL/glut.h>
float angle =0;
void timer(int t)
{
glutTimerFunc(500,timer,t+1);
angle +=90;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotated(angle,0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char *argv[])
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE| GLUT_DEPTH);
glutCreateWindow("week14");
glutTimerFunc(3000,timer,0);
glutDisplayFunc(display);
glutMainLoop();
}
讓旋轉更流暢 修改(藍色) 增加(紅色)
#include <GL/glut.h>
float angle =0;
void timer(int t)
{
glutTimerFunc(33,timer,t+1);
angle +=3;
glutPostRedisplay();
}
void keyboard(unsigned char key,int x,int y)
{
glutTimerFunc(0,timer,0);
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotated(angle,0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char *argv[])
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE| GLUT_DEPTH);
glutCreateWindow("week14");
glutKeyboardFunc(keyboard);
///glutTimerFunc(3000,timer,0);
glutDisplayFunc(display);
glutMainLoop();
}

打開excel
做出一個表格
#include <GL/glut.h>
float angle =0,newAngle=0,oldAngle=0;
float oldX=0;
void timer(int t)
{
if(t<100) glutTimerFunc(33,timer,t+1);
float alpha = t/100.0;
angle = alpha * newAngle +(1-alpha)*oldAngle;
glutPostRedisplay();
}
void keyboard(unsigned char key,int x,int y)
{
glutTimerFunc(0,timer,0);
}
void mouse(int button,int state,int x,int y)
{
if(state==GLUT_DOWN) oldAngle = angle;
if(state==GLUT_UP) newAngle = angle;
}
void motion(int x,int y)
{
angle+= x-oldX;
oldX=x;
glutPostRedisplay();
