把freeglut資料夾移到桌面

打開貝殼專案

設定路徑


#include <GL/glut.h>
void display()
{
glutWireCube(0.8);
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMainLoop();
}
程式碼

把freeglut複製到專案資料夾
執行結果!
課堂作業二
#include <GL/glut.h>
float rot1=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glutSolidTeapot(0.2);
glRotatef(rot1, 0, 0, 1); ///公轉
glTranslatef(0.6,0,0);
glRotatef(rot1*4, 0, 0, 1); ///自轉
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();
}
執行結果如下
float rot1=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glutSolidTeapot(0.2);
glRotatef(rot1, 0, 0, 1); ///公轉
glTranslatef(0.6,0,0);
glRotatef(rot1*4, 0, 0, 1); ///自轉
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();
}
執行結果如下
課堂作業3
製作 機器人 程式碼如下
#include <GL/glut.h>
float rot1=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(0.15,0,0);
glutWireCube(0.1); ///right upper arm
glTranslatef(0.1,0,0);
glutWireCube(0.1); ///right lower arm
glTranslatef(0.1,0,0);
glutWireCube(0.1); ///hand
glPopMatrix();
glPushMatrix();
glTranslatef(-0.15,0,0);
glutWireCube(-0.1); ///left upper arm
glTranslatef(-0.1,0,0);
glutWireCube(-0.1); ///left lower arm
glTranslatef(-0.1,0,0);
glutWireCube(-0.1); ///hand
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();
}
按下 Bulid and run 即可看到機器人的頭、身體、手。
更改以下程式碼
#include <GL/glut.h>
float rot1=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(0.15,0,0);
glTranslatef(0.10,0.05,0);
glRotatef(rot1,0,0,1);
glTranslatef(0.05,0,0);
glutWireCube(0.1); ///right upper arm
///glTranslatef(0.1,0,0);
glTranslatef(0.05,0,0);
glRotatef(rot1,0,0,1);
glTranslatef(0.05,0,0);
glutWireCube(0.1); ///right lower arm
///glTranslatef(0.1,0,0);
glTranslatef(0.05,0,0);
glRotatef(rot1,0,0,1);
glTranslatef(0.05,0,0);
glutWireCube(0.1); ///hand
glPopMatrix();
glPushMatrix();
glTranslatef(-0.15,0.05,0);
glutWireCube(-0.1); ///left upper arm
glTranslatef(-0.1,0,0);
glutWireCube(-0.1); ///left lower arm
glTranslatef(-0.1,0,0);
glutWireCube(-0.1); ///hand
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();
}
可看到機器人的手可以彎曲。
