Week 14 邱芳妤

作業 1

1.建立一貝殼專案

2.輸入以下程式碼：

#include <stdio.h>
FILE *fout=NULL,*fin=NULL;
int main(int argc,char *argv[])
{
    if(fout==NULL)
        fout=fopen("output.txt","w+");
    fprintf(fout,"Hellow World\n");
    return 0;
}

3.執行結果

作業 2

1.BUILD OPTION

2.設定路徑

並打上咒語

3.將Freeglut.dll 放入資料夾

4.輸入程式碼：

#include <GL/glut.h>
#include <stdio.h>
FILE *fout=NULL,*fin=NULL;

void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glutSolidTeapot(0.3);
    glutSwapBuffers();
}

void motion(int x,int y)
{
    if (fout==NULL) fout=fopen("motion.txt","w+");
    fprintf(fout,"%d,%d\n",x,y);
    printf ("%d,%d\n",x,y);
}
int main (int argc,char *argv[])
{
   glutInit(&argc,argv);
   glutInitDisplayMode (GLUT_DOUBLE | GLUT_DEPTH);
   glutCreateWindow ("3D");
   glutDisplayFunc(display);
   glutMotionFunc(motion);
   glutMainLoop();
}



5.執行結果

作業 3

1.輸入程式碼：

按下r鍵使茶壺移動。

#include <GL/glut.h>
#include <stdio.h>
FILE * fout = NULL,*fin = NULL;
int nowX=0,nowY=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glTranslatef((nowX-150)/150.0,(nowY-150)/150.0,0);
    glutSolidTeapot(0.3);
    glPopMatrix();
    glutSwapBuffers();
}
void motion(int x, int y)
{
    if(fout==NULL) fout=fopen("motion.txt","w+");
    fprintf(fout, "%d %d\n",x,y);
    printf("%d %d\n",x,y);
}
void keyboard(unsigned char key, int x, int y)
{
    if(key=='r')
    {
        if(fin==NULL) fin=fopen("motion.txt","r");
        fscanf(fin ,"%d %d\n", &nowX,&nowY);
        printf("%d %d\n",nowX, nowY);
    }
    glutPostRedisplay();
}
int main(int argc,char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("3D");
    glutDisplayFunc(display);
    glutMotionFunc(motion);
    glutKeyboardFunc(keyboard);
    glutMainLoop();
}
