week04-2

1、下載moodle-freeglut mingw檔案，libfreeglut改libglut32.a

2、codeblocks開new project-GLUT project

3、打程式碼

#include<GL/glut.h>

float angle=0,oldX=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

    glRotatef(angle,0,0,1);

    glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

void motion(int x,int y)

{

    angle+=(x-oldX);

    oldX=x;

    display();

}

void mouse(int button,int state,int x,int y)

{

    oldX=x;

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("Week04 Rotate");

    glutDisplayFunc(display);

    glutMotionFunc(motion);

    glutMouseFunc(mouse);

    glutMainLoop();

}
