2019電腦圖學: Week13 鍾嘉穎 2019-05-16

1. 主題: 檔案

1. 打開CodeBlocks

2. 開新Project (Console Application)

3. 把完來的程式碼刪掉

4. 加入新的程式碼

5. 改成以下的程式碼

#include <stdio.h>

FILE * fout=NULL; ///(1)宣告一個檔案指標

int main()

{

fout = fopen("filename.txt","w+"); ///(2)我們要開檔案 ///w+ = read and update

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

fprintf(fout,"Hello World\n"); ///(3)印出來

}

6. 他會自己加一個叫"filename"的檔案然後在裡面打"Hello World"

7. 把20個關節的角度印出來 (開一個叫motion的新檔案)

#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()

{

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

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

fprintf(fout2, "%.2f ", angle[i]); ///把角度印出來

}

2. 主題: 關節、擺動作

1. 先載入freeglut (跟第一週一樣)

1. Google search "freeglut windows"
2. 從Transmission Zero 下載 "freeglut 3.0.0 MinGW Package"

3. 解壓縮後放到桌面

4. 在lib複製一個"libfreeglut.a"命名為"libglut32.a"

5. CodeBlocks 開

6. File -> New -> Project -> GLUT Project

7. 把location改成"C:\Users\user\Desktop\freeglut"

2. 加入程式碼

3. 先做一個茶壺

#include <GL/glut.h>

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glutSolidTeapot( 0.3 );

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();

}

4. 加紅色茶壺

#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();

}

5. 加入旋轉的程式碼(用滑鼠可以轉動)

#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

angle[1] += x-oldX;///NOW2

oldX = x;///NOW2

display();///NOW2

}

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");

glutMouseFunc(mouse);///NOW2

glutMotionFunc(motion);///NOW2

glutDisplayFunc(display);

glutMainLoop();

}

6. 有兩個紅色茶壺(用滑鼠可以轉動)

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

glPushMatrix();

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

3. 主題: 複習

1. 做一個新的檔案把角度存起來 (在freeglut的lib裡)

#include <GL/glut.h>

#include <stdio.h>///NOW_FILE (0)

float angle[20];///NOW2

int angleID=1;///NOW3

if(key=='3') angleID=3;///NOW3

if(key=='4') angleID=4;///NOW3

if(key=='w'){///NOW_FILE

fout = fopen("motion.txt", "w+");///NOW_FILE (2)

}

int main(int argc, char**argv)

{

glutInit(&argc, argv);

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

glutCreateWindow("Week 13 angle motion file");

glutKeyboardFunc(keyboard);///NOW3

glutMouseFunc(mouse);///NOW2

glutMotionFunc(motion);///NOW2

glutDisplayFunc(display);

glutMainLoop();

}

2. 做一個新的檔案把角度存起來 (在freeglut的lib裡)

#include <GL/glut.h>

#include <stdio.h>///NOW_FILE (0)

float angle[20];///NOW2

int angleID=1;///NOW3

FILE * fout = NULL;///NOW_FILE (1)

FILE * fin = NULL;///NOW_FILE_READ (1)

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();

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

glutSolidTeapot( 0.3 );///body

glPushMatrix();///右邊

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

glPushMatrix();

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

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

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

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

glRotatef(angle[4], 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 lower 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

if(fout == NULL) fout = fopen("motion.txt", "w+");///NOW_FILE (2)

for(int i=0;i<20;i++){///NOW3

printf(" %.2f ", angle[i]);///NOW3

fprintf(fout, " %.2f ", angle[i]);///NOW_FILE

}

printf("\n");///NOW3

fprintf(fout, "\n");///NOW_FILE

}

void keyboard(unsigned char key, int x, int y)///NOW3

{///NOW3

if(key=='1') angleID=1;///NOW3

float angle[20];///NOW2

int angleID=1;///NOW3

glPopMatrix();

glutSwapBuffers();

}

int oldX=0;///NOW2
