好忙week12

 week12

step01-1

開啟codeblock

新增一個empty file

#include <stdio.h>

int main()

{

    FILE * fout= fopen("file.txt","w");

    printf("Hello World\n");

    fprintf(fout, "Hello World在檔案裡\n");

}

step01-2新增一個empty file

#include <stdio.h>

int main()

{

    char line[20];

    FILE * fin = fopen("file.txt","r");

    fscanf(fin,"%s",line);

    printf("讀到了:%s\n",line);

    fscanf(fin,"%s",line);

    printf("讀到了:%s\n",line);

}

step01-3新增一個empty file

#include <stdio.h>

int main()

{

    int a[10]={10,20,30,40,50,60,70,80,90,100};

    FILE *fout =fopen("file3.txt","w");

    for(int i=0;i<10;i++){

        fprintf(fout, "%d ",a[i]);

        printf("%d ",a[i]);

    }

    fclose(fout);

    int b[10];

    FILE *fin =fopen("file3.txt","r");

    for(int i=0;i<10;i++){

        fscanf(fin, "%d ",&b[i]);

        printf("%d ",b[i]);

    }

    fclose(fin);

}

step02-1

開啟GLUT專案，用滑鼠使茶壺可以移動

#include <stdio.h>

#include <GL/glut.h>

float teapotX=0,teapotY=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(teapotX,teapotY,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

void  mouse(int button,int state,int x,int y)

{

    teapotX=(x-150)/150.0;

    teapotY=(150-y)/150.0;

    display();

}

int main(int argc,char** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week12");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}

step02-2

複製02-1增加程式碼(紅色)，空白鍵可以回放，file4可以記錄

#include <stdio.h>

#include <GL/glut.h>

float teapotX=0,teapotY=0;

FILE * fout =NULL;

FILE * fin =NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(teapotX,teapotY,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

void  mouse(int button,int state,int x,int y)

{

    teapotX=(x-150)/150.0;

    teapotY=(150-y)/150.0;

    if(state==GLUT_DOWN){

        if(fout==NULL)

            fout=fopen("file4.txt","w");

            fprintf(fout,"%f %f\n",teapotX,teapotY);

    }

    display();

}

void keyboard(unsigned char key,int x,int y)

{

    if(fin==NULL){

        fclose(fout);

        fin=fopen("file4.txt","r");

        }

        fscanf(fin,"%f%f",&teapotX,&teapotY);

        display();

}

int main(int argc,char** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week12");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

step03-1

更改freeglut.dll位置 ，notepad++會一起變

step03-2

更改目錄，codeblock裡也要改

step03-3上傳github

cd desktop

git clone https://github.com/帳號/2023graphicsb

cd 2023graphicsb

git status(紅色)

git add .

git status(綠色)

git config --global user.email 帳號

git config --global user.name 名子

git commit -m "週次"

git push
