來做一個會旋轉的茶壺
#include <GL/glut.h>
float angle = 0;
void display()
{
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );///清理背景不清會有殘影
glutSolidSphere(0.05, 30, 30);///創一個glutSolidSphere來輔助
glPushMatrix();
glRotatef(angle, 0, 0, 1);/// step02,開始旋轉
glTranslatef(0.46, -0.05, 0);/// step1把茶壺移到中心點,可創一個glutSolidSphere來輔助
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
angle++;///把角度++
}
int main(int argc, char *argv[])
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("GLUT Shapes");
glutDisplayFunc(display);
glutIdleFunc(display);///清畫面
glutMainLoop();
}
來做一個會勾在另一個茶壺嘴旋轉的茶壺
