移動茶壺
程式碼:
#include <GL/glut.h>
float x=0,y=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glTranslatef((x-150)/150.0, -(y-150)/150.0,0);
glutSolidTeapot(0.3);
glPopMatrix();///還原矩陣,恢復
glutSwapBuffers();
}
void motion(int nowx, int nowy)
{
x=nowx; y=nowy;
display();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week04_06160221");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}

旋轉茶壺
程式碼:
#include <GL/glut.h>
float x=0,y=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(x,0,1,0);//旋轉
glutSolidTeapot(0.3);
glPopMatrix();///還原矩陣,恢復
glutSwapBuffers();
}
void motion(int nowx, int nowy)
{
x=nowx; y=nowy;
display();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week04_06160221");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
