用滑鼠移動glRotatefglRotatef裡的座標調整人物方向

更改程式碼變成用滑鼠移動圖片方向

變成旋轉茶壺
#include <GL/glut.h>
#include <stdio.h>
float myAngle=0;
void motion(int x,int y)
{
myAngle=x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(myAngle,0,0,1);
glutSolidTeapot( 0.3 );
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week04");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}

選轉茶壺MAX進化版
#include <GL/glut.h>
#include <stdio.h>
float myAngle=0,oldx=0;
void motion(int x,int y)
{
myAngle+=(x-oldx);
oldx=x;
glutPostRedisplay();
}
void mouse(int button,int state,int x,int y)
{
oldx=x;
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(myAngle,0,0,1);
glutSolidTeapot( 0.3 );
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week04");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMouseFunc(mouse);
glutMainLoop();
}
