Yes I do.耶死愛度今天複習貼圖和下載OpenCV

(1) 作業Q &A

1. 下載OpenCV (裝好才能開CodeBlocks)

1. 去 https://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.1/

2. 下載 OpenCV-2.1.0-win32-vs2008.exe

3. 要選 "Add OpenCV to the system PATH for all users"小葉說反正就是有ADD的

4. 要放的路徑: C:\OpenCV2.1

2. 載入freeglut

1. 從Transmission Zero 下載 "freeglut 3.0.0 MinGW Package"

2. 解壓縮後放到桌面

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

4. CodeBlocks 開

5. File -> New -> Project -> GLUT Project

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

3. 設定載入include, bin, lib

1. 在Build Option新增

2. 圖要放在freeglut的bin裏

(2) 複習:貼圖texture

丁丁又開嘞第四次時間暫停，我好想過11月25號ㄚㄚㄚㄚ，對嘞今天用攝影機和運鏡

(1)攝影機和運鏡

三個模式

分別是glOrtho

glFustum

gluPerspective

今天主要用gluPerspective

來達成主要目的

eye眼睛看的方向

center看的中心點

up手拿鏡頭的角度

接著來跑CodeBlocks

先到這個網站

http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/?fbclid=IwAR28YojTgynOCT1AFY77S_10lyrz1DW1syRtZXDZyMUCvSZygUNGR2ms4Yc

下載source裡面有glm.c和glm.h

然後把他們放到你的資料夾，還有要把glm.c改名為glm.cpp

還要下載data

放到你資料夾的bin資料夾

用Notepad++打開source裡的Prejection.c

把Prejection.c的程式碼複製貼上到自己專案的main理

(2)投影、矩陣

先把人形弄上去

(3)位置移動 & 轉動

要出事了怎麼辦?高雄發大財阿，至少我還沒開始吃草

(1) 主題: 檔案

教你存檔案

先印個Hello World

#include<stdio.h>
FILE * fout=NULL;
int main()
{
fout=fopen("filename.txt","w+");
for(int i=0;i<20;i++){
fprintf(fout,"Hello World\n");
}
}

(2)主題:關節、擺動作

我們現在就開始寫關節的部分

首先，我們先設定20個關節的角度

記得要加空格增加可讀性

#include<stdio.h>

FILE * fout2=NULL;

FILE * fin2=NULL;

float angle[20];

int main()

{

fout2=fopen("motion.txt","w+");

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

fprintf(fout2," %.2f ",angle[i]);

}

先處理第一個關節

#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

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();
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

glutMainLoop();
}

第二個關節
#include <GL/glut.h>

{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glColor3f(1, 1, 1);///white

glutSolidTeapot( 0.2 );///right lower arm
glPopMatrix();
glPopMatrix();
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();

}

把左邊的關節也做出來

Yes I do.耶死愛度 今天複習貼圖 和下載OpenCV

(1) 作業Q &A

1. 下載OpenCV (裝好才能開CodeBlocks)

1. 去 https://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.1/

2. 下載 OpenCV-2.1.0-win32-vs2008.exe

3. 要選 "Add OpenCV to the system PATH for all users"小葉說反正就是有ADD的

4. 要放的路徑: C:\OpenCV2.1

(2) 複習:貼圖texture

(3) 複習:打光

(4) 複習:模型

丁丁又開嘞第四次時間暫停，我好想過11月25號ㄚㄚㄚㄚ，對嘞今天用攝影機和運鏡

(1)攝影機和運鏡

(2)投影、矩陣

(3)位置移動 & 轉動

(4)背景貼圖

計時器開起來嘿嘿

電腦圖學(1)先練習計時器

(2)內差公式

(3)動畫
