 ## week12-1_obj_gundam_hand1_hand2

準備工作

1:opencv要裝起來,要記的勾Add Path,不要改目錄,再重開codeblocks

2:把codeblocks setting-complier加入三個設定

-search directories的complier要設c:\opencv2.1\include

-search directories的linker要設c:\OpenCV2.1\lib

-linker setting 要設cv210 cxcore210 highgui210

再把github上週的程式,拿下來

1:把week11-3_obj_gundanm_hand1_hand2複製到桌面

2:改目錄名week12-1_obj_gundam_hand1_hand2

3:把cbp,改檔名week12-1_obj_gundam_hand1_hand2

## week12-2_obj_gundam_upper_lower_hand

0.先把week12-1_obj_gundam_upper_hand1_hand_2整個目錄,複製新的目錄,改目錄名

week12-2_obj_gundam_upper_lower_hand_上手臂`下手臂的意思

1:把cbp檔,修改檔名成week12-2_obj_gundam_upper_lower_hand

2:CodeBlocks把cbp檔開起來,把下面的專案Title改成week12-2_obj_gundam_upper_lower_hand

```cpp 

GLMmodel  *  upper = NULL;

GLMmodel  *  lower = NULL;

```

再把 drawmodel() 複製兩份，分別叫 void 

drawLower(){...}

裡面的 pmodel 都改成 upper 或 lower 檔名改成 upper.obj 和 lower.obj

利用 MAYA 開啟

## week12-3_obj_gundam_body_upper_lower

0.把目錄複製 week12-3_obj_gundanm_body_upper_lower

1:再把裡面cbp改檔名成week12-3_obj_gundam_body_upper_lower.cbp

2:再把Title改成week12-3_obj_gundam_body_upper_lower

3:在開啟codeblock把week12-3_obj_gundam_body_upper_lower.cbp開起來

接下來,maya要切出身體囉body.obj

最後,程式碼加上

GLMmodel*body=NULL;

再把voud drawBody()複製出來,改用body.obj和body body body
