先建立一個貝殼專案,把freeglut的設定都設定好
輸入程式碼
#include <GL/glut.h>
void display()
{
glutWireCube(0.3);//方塊
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMainLoop();
}
作業二
茶壺公轉、自轉
修改程式碼
#include <GL/glut.h>
float rot1=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);///清背景
glPushMatrix();
glutSolidTeapot(0.2);
glRotatef(rot1,0,0,1);
glTranslatef(0.6,0,0);
glRotatef(rot1*4,0,0,1);
glutSolidTeapot(0.2);
glPopMatrix();
glutSwapBuffers();
}
void motion(int x,int y)
{
rot1=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
做出半個機器人
#include <GL/glut.h>
float rot1=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);///清背景
glPushMatrix();
glutWireCube(0.2);///body
glPushMatrix();
glTranslatef(0,0.15,0);
glutWireCube(0.1);///head
glPopMatrix();
glPushMatrix();///右手
glTranslatef(0.15,0,0);
glutWireCube(0.1);
glTranslatef(0.1,0,0);
glutWireCube(0.1);
glTranslatef(0.1,0,0);
glutWireCube(0.1);
glPopMatrix();
glPushMatrix();///左手
glTranslatef(-0.15,0,0);
glutWireCube(-0.1);
glTranslatef(-0.1,0,0);
glutWireCube(-0.1);
glTranslatef(-0.1,0,0);
glutWireCube(-0.1);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
void motion(int x,int y)
{
rot1=x;
glutPostRedisplay();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
修改程式碼,讓手會動
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);///清背景
glPushMatrix();
glutWireCube(0.2);///body
glPushMatrix();
glTranslatef(0,0.15,0);
glutWireCube(0.1);///head
glPopMatrix();
glPushMatrix();///右手
//glTranslatef(0.15,0,0);
glTranslatef(0.10,0.05,0);
glRotatef(rot1,0,0,1);
glTranslatef(0.05,0,0);//拆成兩個
glutWireCube(0.1);///手臂1
//glTranslatef(0.1,0,0);
glTranslatef(0.05,0,0);
glRotatef(rot1,0,0,1);
glTranslatef(0.05,0,0);
glutWireCube(0.1);///手臂2
//glTranslatef(0.1,0,0);
glTranslatef(0.05,0,0);
glRotatef(rot1,0,0,1);
glTranslatef(0.05,0,0);
glutWireCube(0.1);///手掌
glPopMatrix();
glPushMatrix();///左手
glTranslatef(-0.15,0.05,0);
glutWireCube(-0.1);
glTranslatef(-0.1,0,0);
glutWireCube(-0.1);
glTranslatef(-0.1,0,0);
glutWireCube(-0.1);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
