week13

 

示範複習作業/考試的 TRT(實際例子

#include<GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glRectf(0.3,0.5, -0.3,-0.5);///畫個方形(不一定是正方)

    glutSwapBuffers();


}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(600,600);

    glutCreateWindow("week13 rect TRT");


    glutDisplayFunc(display);

    glutMainLoop();

}




多加個小方塊

#include<GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,1);///白

    glRectf(0.3,0.5, -0.3,-0.5);///四邊形當身體

    glPushMatrix();

        ///glTranslatef()

        ///glRotatef()

        ///glTranslatef()

    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 TRT");


    glutDisplayFunc(display);

    glutMainLoop();

}




TRT

把手的軸心放在正中心(1)

#include<GL/glut.h>
void display()
{
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);///白
    glRectf(0.3,0.5, -0.3,-0.5);///四邊形當身體
    glPushMatrix();
        ///glTranslatef()
        ///glRotatef()
        glTranslatef(-0.3,-0.4,0);///(1)把軸心放在中心
    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 TRT");

    glutDisplayFunc(display);
    glutMainLoop();
}



旋轉(2)

#include<GL/glut.h>
float angle=45;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);///白
    glRectf(0.3,0.5, -0.3,-0.5);///四邊形當身體
    glPushMatrix();
        ///glTranslatef()
        glRotatef(angle,0,0,1);///(2)
        glTranslatef(-0.3,-0.4,0);///(1)把軸心放在中心
    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 TRT");

    glutDisplayFunc(display);
    glutMainLoop();
}


改整體位置(3)

#include<GL/glut.h>
float angle=45;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);///白
    glRectf(0.3,0.5, -0.3,-0.5);///四邊形當身體
    glPushMatrix();
        glTranslatef(0.3,0.4,0);///(3)整體移位
        glRotatef(angle,0,0,1);///(2)
        glTranslatef(-0.3,-0.4,0);///(1)把軸心放在中心
    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 TRT");

    glutDisplayFunc(display);
    glutMainLoop();
}


藉由滑鼠旋轉手

#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);
    oldX=x;
    glutPostRedisplay();///請GLUT重畫畫面
}
void display()
{
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);///白
    glRectf(0.3,0.5, -0.3,-0.5);///四邊形當身體
    glPushMatrix();
        glTranslatef(0.3,0.4,0);///(3)整體移位
        glRotatef(angle,0,0,1);///(2)
        glTranslatef(-0.3,-0.4,0);///(1)把軸心放在中心
    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 TRT");

    glutMouseFunc(mouse);
    glutMotionFunc(motion);
    glutDisplayFunc(display);

    glutMainLoop();
}

再加一個手臂也可TRT

#include<GL/glut.h>
float angle=0 ,oldX=0;
void mouse(int button,int state,int x,int y){
    oldX=x;
}
void motion(int x,int y){

    angle+=(x-oldX);
    oldX=x;
    glutPostRedisplay();///請GLUT重畫畫面
}
void display()
{
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);///白
    glRectf(0.3,0.5, -0.3,-0.5);///四邊形當身體
    glPushMatrix();
        glTranslatef(0.3,0.4,0);///(3)整體移位
        glRotatef(angle,0,0,1);///(2)
        glTranslatef(-0.3,-0.4,0);///(1)把軸心放在正中心
        glColor3f(1,0,0);///紅
        glRectf(0.3,0.5,0.7,0.3);///上手臂

            glPushMatrix();

                glTranslatef(0.7,0.4,0);///(3)整體移位
                glRotatef(angle,0,0,1);///(2)
                glTranslatef(-0.7,-0.4,0);///(1)把軸心放在正中心

                glColor3f(0,1,0);///綠
                glRectf(0.7,0.5,1.0,0.3);///上手臂

            glPopMatrix();
    glPopMatrix();
    glutSwapBuffers();

}
int main(int argc, char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutInitWindowSize(600,600);
    glutCreateWindow("week13 rect TRT");

    glutMouseFunc(mouse);
    glutMotionFunc(motion);
    glutDisplayFunc(display);

    glutMainLoop();
}


兩隻手都可旋轉

#include<GL/glut.h>
float angle=0 ,oldX=0;
void mouse(int button,int state,int x,int y){
    oldX=x;
}
void motion(int x,int y){

    angle+=(x-oldX);
    oldX=x;
    glutPostRedisplay();///請GLUT重畫畫面
}
void display()
{
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);///白
    glRectf(0.3,0.5, -0.3,-0.5);///四邊形當身體

    glPushMatrix();///右邊
        glTranslatef(0.3,0.4,0);///(3)整體移位
        glRotatef(angle,0,0,1);///(2)
        glTranslatef(-0.3,-0.4,0);///(1)把軸心放在正中心
        glColor3f(1,0,0);///紅
        glRectf(0.3,0.5,0.7,0.3);///上手臂

            glPushMatrix();
                glTranslatef(0.7,0.4,0);///(3)整體移位
                glRotatef(angle,0,0,1);///(2)
                glTranslatef(-0.7,-0.4,0);///(1)把軸心放在正中心

                glColor3f(0,1,0);///綠
                glRectf(0.7,0.5,1.0,0.3);///下手臂
            glPopMatrix();
    glPopMatrix();


     glPushMatrix();///左邊
        glTranslatef(-0.3,0.4,0);///(3)整體移位
        glRotatef(angle,0,0,1);///(2)
        glTranslatef(0.3,-0.4,0);///(1)把軸心放在正中心
        glColor3f(1,0,0);///紅
        glRectf(-0.3,0.5,-0.7,0.3);///下手臂

            glPushMatrix();
                glTranslatef(-0.7,0.4,0);///(3)整體移位
                glRotatef(angle,0,0,1);///(2)
                glTranslatef(0.7,-0.4,0);///(1)把軸心放在正中心

                glColor3f(0,1,0);///綠
                glRectf(-0.7,0.5,-1.0,0.3);///上手臂
            glPopMatrix();
    glPopMatrix();

    glutSwapBuffers();

}
int main(int argc, char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutInitWindowSize(600,600);
    glutCreateWindow("week13 rect TRT");

    glutMouseFunc(mouse);
    glutMotionFunc(motion);
    glutDisplayFunc(display);

    glutMainLoop();
}




用鍵盤按鍵指定要旋轉哪一部分

#include<GL/glut.h>
float angle[20] ,oldX=0;
int angleID=0;
void keyboard(unsigned char key,int x,int y)
{
    if(key=='0') angleID=0;///0號關節
    if(key=='1') angleID=1;
    if(key=='2') angleID=2;
    if(key=='3') angleID=3;

}
void mouse(int button,int state,int x,int y){
    oldX=x;
}
void motion(int x,int y){

    angle[angleID]+=(x-oldX);
    oldX=x;
    glutPostRedisplay();///請GLUT重畫畫面
}
void display()
{
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glColor3f(1,1,1);///白
    glRectf(0.3,0.5, -0.3,-0.5);///四邊形當身體

    glPushMatrix();///右邊
        glTranslatef(0.3,0.4,0);///(3)整體移位
        glRotatef(angle[0],0,0,1);///(2)
        glTranslatef(-0.3,-0.4,0);///(1)把軸心放在正中心
        glColor3f(1,0,0);///紅
        glRectf(0.3,0.5,0.7,0.3);///上手臂

            glPushMatrix();
                glTranslatef(0.7,0.4,0);///(3)整體移位
                glRotatef(angle[1],0,0,1);///(2)
                glTranslatef(-0.7,-0.4,0);///(1)把軸心放在正中心

                glColor3f(0,1,0);///綠
                glRectf(0.7,0.5,1.0,0.3);///下手臂
            glPopMatrix();
    glPopMatrix();


     glPushMatrix();///左邊
        glTranslatef(-0.3,0.4,0);///(3)整體移位
        glRotatef(angle[2],0,0,1);///(2)
        glTranslatef(0.3,-0.4,0);///(1)把軸心放在正中心
        glColor3f(1,0,0);///紅
        glRectf(-0.3,0.5,-0.7,0.3);///上手臂

            glPushMatrix();
                glTranslatef(-0.7,0.4,0);///(3)整體移位
                glRotatef(angle[3],0,0,1);///(2)
                glTranslatef(0.7,-0.4,0);///(1)把軸心放在正中心

                glColor3f(0,1,0);///綠
                glRectf(-0.7,0.5,-1.0,0.3);///下手臂
            glPopMatrix();
    glPopMatrix();
    glutSwapBuffers();

}
int main(int argc, char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutInitWindowSize(600,600);
    glutCreateWindow("week13 rect TRT");

    glutMouseFunc(mouse);
    glutMotionFunc(motion);
    glutKeyboardFunc(keyboard);
    glutDisplayFunc(display);

    glutMainLoop();
