(1)T-R-T茶壺


#include <GL/glut.h>
#include <stdio.h>
float x1=-0.4, y1=0, x2=0, y2=0, angle=0;
void display()
{
    glEnable(GL_DEPTH_TEST);
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glTranslatef(x1, y1, 0);//要掛在哪裡?
        glRotatef(angle, 0,0,1);
        glTranslatef(-0.25, -0.11, 0);
        glColor3f(1,1,0);
        glutSolidTeapot(0.2);
    glPopMatrix();
    glPushMatrix();
        glTranslatef(x2, y2, 0);
        glColor3f(1,0,0);
        glutSolidTeapot(0.2);
    glPopMatrix();
    glFlush();///先不用 glutSwapBuffers(); 配合 glutInitDisplayMode(GLUT_DOUBLE);
}
void keyboard(unsigned char key, int x, int y)
{

    glutPostRedisplay();
}
int main(int argc, char**argv)
{

    glutCreateWindow("Robot3D");
    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard);

(2)2個關節連在一起



#include <GL/glut.h>
#include <stdio.h>
float x1=-0.4, y1=0, x2=0, y2=0, angle=0, angle2=0;
void display()
{
    glEnable(GL_DEPTH_TEST);
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();///BLUE
        glTranslatef(x2, y2, 0);//要掛在哪裡?
        glRotatef(angle, 0,0,1);
        glColor3f(0,0,1);
        glutSolidTeapot(0.2);
        glPushMatrix();///GREEN
            glTranslatef(x1, y1, 0);
            glRotatef(angle2, 0,0,1);
            glTranslatef(-0.25, -0.11, 0);
        glColor3f(0,1,0);
        glutSolidTeapot(0.2);
        glPopMatrix();
    glPopMatrix();
    glFlush();///先不用 glutSwapBuffers(); 配合 glutInitDisplayMode(GLUT_DOUBLE);
}
void keyboard(unsigned char key, int x, int y)
{
    if(key=='1') x1+=0.1;
    if(key=='2') x1-=0.1;
    if(key=='3') y1+=0.1;
    if(key=='4') y1-=0.1;
    if(key=='5') angle+=10;
    if(key=='6') angle-=10;
    if(key=='7') angle2+=10;
    if(key=='8') angle2-=10;
    printf("%f %f\n", x1, y1);
    glutPostRedisplay();
}
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutCreateWindow("Robot3D");
    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard);
    glutMainLoop();
}




(3)利用滑鼠與鍵盤 讓關節轉動


#include <GL/glut.h>

    if(key=='1') now=1;
    if(key=='2') now=2;
    if(key=='3') now=3;
    if(key=='4') now=4;
    glutPostRedisplay();
}
void drawBody()
{
    glPushMatrix();
    glScalef(1,0.5,0.5);
    glutSolidCube(1);
    glPopMatrix();
}
void drawArm()
{
    glPushMatrix();
    glScalef(0.6,0.3,0.3);
    glutSolidCube(1);
    glPopMatrix();
}
void display()
{

    glColor3ub(166,132,100);
    GLfloat pos[]={0,0,-1,0};
    glLightfv(GL_LIGHT0,GL_POSITION,pos);
    glEnable(GL_LIGHT0);
    glEnable(GL_LIGHTING);
    glEnable(GL_DEPTH_TEST);
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();
        glTranslatef(0.5, 0, 0);///最後一步, 把樓下的 "會對Arm Joint做旋轉的東西" 再移到右上 掛上去 ver 4
        glRotatef(angle[1], 0,0,1);///把下面整團, 都對中間做旋轉 ver 3
        glTranslatef(0.25, 0,0);///這是把它往右移, Arm Joint在中間 ver 2
        glColor3f(0,0,1);
        drawArm();///這是個Arm ver 1  Right Upper Arm
        glPushMatrix();
            glTranslatef(0.25, 0, 0);///最後一步, 把樓下的 "會對Arm Joint做旋轉的東西" 再移到右上 掛上去 ver 4

            glTranslatef(0.25, 0,0);///這是把它往右移, Arm Joint在中間 ver 2
            glColor3f(0,1,0);
            drawArm(); ///Right Lower Arm
        glPopMatrix();
    glPopMatrix();
    glPushMatrix();
        glTranslatef(-0.5, 0, 0);///最後一步, 把樓下的 "會對Arm Joint做旋轉的東西" 再移到右上 掛上去 ver 4
        glRotatef(-angle[3], 0,0,1);///把下面整團, 都對中間做旋轉 ver 3
        glTranslatef(-0.25, 0,0);///這是把它往右移, Arm Joint在中間 ver 2
        glColor3f(0.5,0.5,1);
        drawArm();///這是個Arm ver 1  Left Upper Arm
        glPushMatrix();
            glTranslatef(-0.25, 0, 0);///最後一步, 把樓下的 "會對Arm Joint做旋轉的東西" 再移到右上 掛上去 ver 4
            glRotatef(-angle[4], 0,0,1);///把下面整團, 都對中間做旋轉 ver 3
            glTranslatef(-0.25, 0,0);///這是把它往右移, Arm Joint在中間 ver 2
            glColor3f(0.5,1,0.5);
            drawArm(); ///Left Lower Arm
        glPopMatrix();
    glPopMatrix();
    drawBody(); ///body
    glFlush();
}
void motion(int x,int y)
{
    angle[now]-=y-oldY;
    oldY=y; oldX=x;
}
void mouse(int button,int state,int x,int y)
{
    if(state==GLUT_DOWN)
    {
        oldX=x; oldY=y;
    }
}
void timer(int t)
{
    glutTimerFunc(20,timer,t+1);
    //angle++;
    glutPostRedisplay();
}
int main(int argc, char *argv[])
{
    glutInit(&argc, argv);
    glutCreateWindow("T-R-T test");

    glutTimerFunc(20,timer,0);
    glutMouseFunc(mouse);
    glutMotionFunc(motion);
    glutKeyboardFunc(keyboard);
    glutMainLoop();
}
