(1)

1-1.開 CodeBlocks/GLUT/GLUT

1-2.貼十行程式，把茶壺換Rect();  ->方形

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glRectf(0.3,0.5,-0.3,-0.5);

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutInitWindowSize(600,600);

    glutCreateWindow("Week13 rect");

    glutDisplayFunc(display);

    glutMainLoop();

}

1-3.刪註解 -->加顏色跟手臂 ，改軸心 ，加角度，手掛回身體

#include <GL/glut.h>

float angle=45;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,1);

    glRectf(0.3,0.5,-0.3,-0.5);

    glPushMatrix();

        ///glTranslatef(0.3,0.4,0);

        ///glRotatef(angle,0,0,1);

        ///glTranslatef(-0.3,-0.4,0);把軸心放中心

        glColor3f(1,0,0);///紅

        glRectf(0.3,0.5,0.7,0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    ///glutInitWindowSize(600,600);

    glutCreateWindow("Week13 rect");

    glutDisplayFunc(display);

    glutMainLoop();

}

1-4.按滑鼠可以旋轉手臂

#include <GL/glut.h>

float angle=45,oldX=0;

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

    oldX=x;

}

void motion(int x,int y){

    angle +=(x-oldX);

    glutPostRedisplay();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,1);

    glRectf(0.3,0.5,-0.3,-0.5);

    glPushMatrix();

        glTranslatef(0.3,0.4,0);

        glRotatef(angle,0,0,1);

        glTranslatef(-0.3,-0.4,0);

        glColor3f(1,0,0);

        glRectf(0.3,0.5,0.7,0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    ///glutInitWindowSize(600,600);

    glutCreateWindow("Week13 rect");

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

}
