課堂作業 1 :
1. 建立一個新貝殼專案
2. include、link位址
3. freeglut、opengl32、glu32、gdi32、winmm
4. 執行 : 失敗 因為沒有放入freeglut.dll黨
5. 畫出一個方塊
課堂作業 2 : 茶壺自轉
1. 茶壺
2. 滑鼠點擊轉
程式碼 :
#include <GL/glut.h>
float rot1=0;
void display()
{
glPushMatrix();
glRotatef(rot1, 0, 0, 1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void motion(int x, int y)
{
rot1=x;
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Robot");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
3. 滑鼠按著不放轉
程式碼 :
#include <GL/glut.h>
float rot1=0;
void display()
{
glPushMatrix();
glRotatef(rot1, 0, 0, 1);
glutSolidTeapot(0.3);
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();
}
4. 清背景 滑鼠按著不放轉
程式碼 :
#include <GL/glut.h>
float rot1=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(rot1, 0, 0, 1);
glutSolidTeapot(0.3);
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();
}
5. 自轉+公轉
程式碼 :
#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();
}
課堂作業 3 : 畫出機器人
1. 練習畫出方格
2. 畫出機器人的頭、身體、右手
3. 畫出左手
4. 手可以隨滑鼠移動揮舞
5. 手可以隨滑鼠移動彎曲
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();
}
