2019電腦圖學: 林芷祺的筆記Week13

WEEK13 2019/5/16

主題 : 檔案

主題 : 關節，擺動作

貝殼專案

1.開啟codeblocks的專案

2.將程式碼改掉，執行後會在專案檔案裡面出現一個filename.txt，裡面會有印的東西

#include <stdio.h>

FILE * fout=NULL;///(1)宣告一個檔案指標

int main()

{///檔案寫檔

fout=fopen("filename.txt","w+");///(2)開檔案

for(int i=0;i<20;i++){

fprintf(fout,"Hello World\n");///(3)印到檔案

}

3.將程式碼改掉，執行後會在專案檔案裡面會出現一個motion.txt，裡面會有印的東西

#include <stdio.h>

FILE * fout2=NULL;///寫另一個檔案

FILE * fin2=NULL;///讀另一個檔案

float angle[20];///有20個關節的角度

int main()

{///檔案寫檔

fout2=fopen("motion.txt","w+");///另一個有關節的檔案

for(int i=0;i<20;i++){

fprintf(fout2," %.2f ",angle[i]);///印到檔案，要加空格

}

GLUT專案 : T-R-T

4.開啟glut專案(檔案位置記得存!!!!!!!!)

5.搜尋freeglut window下載Download freeglut 3.0.0 for MinGW

6.複製檔案位置

7.複製libfreeglut.a--->改成libglut32.a

8.把GLUT的main.cpp裡的程式全部刪掉，改成

#include <GL/glut.h>

float angle[20];///NOW2

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();

glColor3f(1, 1, 1);///white

glutSolidTeapot( 0.3 );///body

glPushMatrix();

glTranslatef(0.3, 0, 0);

glColor3f(1, 0, 0);///red

glutSolidTeapot( 0.2 );///right arm

glPopMatrix();

glutSwapBuffers();

}

int main(int argc, char**argv)

{

glutInit(&argc, argv);

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

///glutInitWindowSize(600,600);///可以開大一點的window

glutCreateWindow("Week 13 angle motion file");

glutDisplayFunc(display);

glutMainLoop();

}

9.執行(有紅色的關節)

#include <GL/glut.h>

float angle[20];///NOW2

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();

glColor3f(1, 1, 1);///white

glutSolidTeapot( 0.3 );///body

glPushMatrix();

glTranslatef(0.2, 0, 0);///NOW2 (3)掛上去

glRotatef(angle[1], 0,0,1);///NOW2 ///(2)旋轉

glTranslatef(0.15, 0, 0);///NOW2 (1)旋轉中心

glColor3f(1, 0, 0);///red

glutSolidTeapot( 0.2 );///right arm

glPopMatrix();

glutSwapBuffers();

}

int oldX=0;///NOW2

void mouse(int button, int state, int x, int y)///NOW2

{///NOW2

oldX = x;///NOW2

}

void motion(int x, int y)///NOW2

{///NOW2

oldX = x;///NOW2

display();///NOW2

}

int main(int argc, char**argv)

{

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

///glutInitWindowSize(600,600);///可以開大一點的window

glutCreateWindow("Week 13 angle motion file");

glutMouseFunc(mouse);///NOW2

glutMotionFunc(motion);///NOW2

glutDisplayFunc(display);

glutMainLoop();

}

10.執行(可以用滑鼠操控紅色的關節)

glPushMatrix();

glTranslatef(0.2, 0, 0);///NOW2 (3)掛上去
