glTranslatef調整左右前後上下
glRotatef調整旋轉
glScalef調整大小
先把茶壺作出來
#include<GL/glut.h>
void display()
{
glutSolidTeapot(0.3);
glutSwapBuffers();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week04");
glutDisplayFunc(display);
glutMainLoop();
}
#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();
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");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
