程式碼:
#include <GL/glut.h>
void display()
{
glutWireCube(0.3);
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMainLoop();
}
作業二: 做出自轉與公轉的茶壺


程式碼:
#include <GL/glut.h>
float rotl=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glutSolidTeapot(0.2);
glRotatef(rotl,0,0,1);
glTranslatef(0.6,0,0);
glRotatef(rotl*4,0,0,1);
glutSolidTeapot(0.2);
glPopMatrix();
glutSwapBuffers();
}
void motion(int x,int y)
{
rotl=x;
glutPostRedisplay();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
作業三 : 製作機器人
做出手臂

可旋轉的手臂

同方向的手臂

程式碼:
#include <GL/glut.h>
float rotl=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glutWireCube(0.2);///body
glPushMatrix();
glTranslatef(0,0.15,0);
glutWireCube(0.1);///head
glPopMatrix();
glPushMatrix();
glTranslatef(0.10,0.05,0);
glRotatef(rotl,0,0,1);
glTranslatef(0.05,0.0,0);
glutWireCube(0.1);///right upper arm
glTranslatef(0.05,0,0);
glRotatef(rotl,0,0,1);
glTranslatef(0.05,0,0);
glutWireCube(0.1);///right lower arm
glTranslatef(0.05,0,0);
glRotatef(rotl,0,0,1);
glTranslatef(0.05,0,0);
glutWireCube(0.1);///hand
glPopMatrix();
glPushMatrix();
glTranslatef(-0.10,0.05,0);
glRotatef(rotl,0,0,-1);
glTranslatef(-0.05,0.0,0);
glutWireCube(-0.1);///left upper arm
glTranslatef(-0.05,0,0);
glRotatef(rotl,0,0,-1);
glTranslatef(-0.05,0,0);
glutWireCube(-0.1);///left lower arm
glTranslatef(-0.05,0,0);
glRotatef(rotl,0,0,-1);
glTranslatef(-0.05,0,0);
glutWireCube(-0.1);///hand
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
void motion(int x,int y)
{
rotl=x;
glutPostRedisplay();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
