移動 glTranslatef
旋轉glRotatef
縮放glScalef

swap

旋轉是沿著中心點轉
左右邊在轉
C
mouse轉動
#include<GL/glut.h>
void motion(int x,int y)
{
}
void display()
{
glClearColor(0,0,1,1);
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(1,0,0);
glutSolidTeapot(0.3);
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DEPTH | GLUT_DEPTH);
glutCreateWindow("hello3D");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
左右轉動


Buffer :

Double :

階層旋轉、移動
#include<GL/glut.h>
float rotX=0,rotY=0;
void display()
{
glClearColor(0,0,1,1);
glClear(GL_COLOR_BUFFER_BIT);
glPushMatrix();
glRotatef(rotX,1,0,0);
glRotatef(rotY,0,1,0);
glColor3f(1,1,0);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void motion (int x, int y)
{
rotX = x;
rotY = y;
display();
}
int main(int argc,char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("hello 3D");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
