開新專案(貝殼空專案)
設定build options

#include <GL/glut.h>
void display()
{
glPushMatrix();
glutSolidTeapot(0.3);
glTranslatef(0.5,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int main (int argc, char **argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMainLoop();
}
呈現兩個茶壺
#include <GL/glut.h>
float rot1=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); ///清除
glPushMatrix();
glutSolidTeapot(0.3);
glTranslatef(0.5,0,0);
glRotatef(rot1,0,0,1); ///自轉
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void motion(int x, int y)
{
rot1=x;
glutPostRedisplay();
}
int main (int argc, char **argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
茶壺可以公轉和自轉

2.關節轉動T-R-T
