YT's 電腦圖學 Week09

 #week09-0_sample 

1. 安裝freeglut --> File -->New --> Project --> GLUT專案 week09-0_sample

 #複習上週的week08-3_glm_gundam_opencv_texture_lighting 

要把環境設定好: Open CV

1. 下載桌面上的葉正聖上課用軟體 OpenCV-2.1.0

!注意! (1) 要選第二個 Add Path

         (2) 目錄不要改

          (3) 要重開 CodeBlocks

CodeBlocks --> Setting -->Compiler裡，要設定3個地方:

• Search directories 的 compiler 要加入 C:\OpenCV2.1\include
• Linker 的 lib 要加入 C:\OpenCV2.1\lib
• Linker 設定，要加入 cv210 、 cxcore210 、 highgui210

2. 要把上週的 GitHub 倉庫複製下來

安裝Git，開啟 Git Bash小黑 (要選Launch Git Bash)

指令: (1) cd desktop

        (2) git clone https://github.com/ccytong/2024graphicsa

        (3) cd 2024graphicsa

        (4) start .

把上週的week08-3_glm_gundam_opencv_texture_lighting開起來

1. File --> Open 到week08-3的目錄，點開.cbp檔 (CodeBlocks Project檔)

2. Build&Run 就可以

! 把剛剛的專案變成week09-1_glm_gundam_opencv_texture_lighting

1. 把剛剛的專案先關起來，按右鍵Close Project (這樣才不會被鎖)

2. 把整個week08-3_glm_gundam_opencv_texture_lighting檔案複製到桌面，改名為week09-1_glm_gundam_opencv_texture_lighting

3. 把檔案裡面的week08-1_glm_gundam_opencv_texture_lighting.cbp改名為week09-1_glm_gundam_opencv_texture_lighting.cbp

4. 把week09-1_glm_gundam_opencv_texture_lighting.cbp按右鍵，用Notepad++開啟，全部的week08-3要全改成week09-1 (要記得存檔 !)

5. 再用 CodeBlocks File-Open 開啟就好了 !

為了改得更徹底，main.cpp裡的 glutCreateWindow("week08 Gundam") 改成 ("week09-1")

 #week09-2_glutSolidTeapot_glutSolidCube_glutSolidSphere (實心)

1. 貼上11行glut程式碼  

#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);

glutCreateWindow("week09 Microsoft Visual Studio");

glutDisplayFunc(display);

glutMainLoop();

}

2. 畫3個圖案(黃框)

 #week09-3_glutWireTeapot_glutWireCube_glutWireSphere (空心)

1. 貼上上一個的程式碼

2. 把實心的圖案改成空心的 (Solid --> Wire)
