Week14切換關節、移動、旋轉
開啟github將final_project下載下來
將libfreeglut.a改為libglut32.a
旋轉茶壺程式
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(angle,0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void timer(int t)
{
glutTimerFunc(500,timer,t+1);
angle+=50;
glutPostRedisplay();
}
int main(int argc,char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14");
glutDisplayFunc(display);
glutTimerFunc(2000,timer,0);
glutMainLoop();
}
用鍵盤控制茶壺程式
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(angle, 0, 0, 1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void timer(int t)
{
glutTimerFunc(500, timer, t+1);
angle += 90;
glutPostRedisplay();
}
void keyboard(unsigned char key, int x, int y)
{
glutTimerFunc(0, timer, 0);
}
int main(int argc, char ** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14");
glutDisplayFunc(display);
glutKeyboardFunc(keyboard);
///glutTimerFunc(2000, timer, 0);
glutMainLoop();
}
使用滑鼠控制茶壺
#include <GL/glut.h>
float angle=0, oldAngle=0, newAngle=0; ///step02-1宣告變數
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(angle, 0, 0, 1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void timer(int t) ///step01-1 你的timer()函式,做對應動作
{
if(t<100) glutTimerFunc(50, timer, t+1);
float alpha = t/100.0;
angle = newAngle*alpha + (1-alpha) * oldAngle;
glutPostRedisplay(); ///重畫畫面
}
void motion(int x, int y)
{
angle = x;
glutPostRedisplay();
}
void mouse(int button, int state,int x, int y)
{
if(state==GLUT_DOWN) oldAngle = x; ///step02-1按下去
if(state==GLUT_UP) newAngle = x; ///step02-1放開來
glutPostRedisplay(); ///step02-1重畫畫面
}
void keyboard(unsigned char key, int x, int y)
{
glutTimerFunc(0, timer, 0);
}
int main(int argc, char ** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14");
glutDisplayFunc(display);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutKeyboardFunc(keyboard);
///glutTimerFunc(2000, timer, 0);
glutMainLoop();
}
