旋轉
1.
#include <GL/glut.h>
float angle=0;///旋轉的角度
void motion(int x, int y)///mouse motion拖著移動時,會叫motion()
{
angle=x;///老師用上週較差的方法,直接把mouse座標,變轉動角度
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(0.5, 0.14, 0);
glRotatef(angle, 0,0,1);
glTranslatef(0.45, -0.08, 0);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("Week05 TRT");
glutDisplayFunc(display);
glutMotionFunc(motion);
