魚鱗☆ﾟ.*･｡電腦圖學 Week12

 1. week12-1_gundam_handA_handB

(1)安裝freeglut

(2)安裝opencv，重開CodeBlocks --> 詳細去看魚鱗電腦圖學Week05-1

(3)把上週的 week11-2_obj_gundam_opencv_texture_lighting 下載下來，改名叫 week12-1_gundam_handA_handB，cbp檔也要改

(4)open file，然後去properties中的title把名字改成week12-1_gundam_handA_handB

(5)把MyBody註解掉，加一顆在中心的圓球，並把手的關節挪到中心

2. week12-2_glm_gundam_upper_lower

(1)目標：要把上手臂、下手臂 切好、讀入

##事先準備：Maya開起來，把 HandA.obj 讀入，切割出 upper.obj 和 lowerA.obj ☆ﾟ.*･｡

(2)再把 week12-1_gundam_handA_handB 資料夾複製成 week12-2_glm_gundam_upper_lower

(3)把handA程式改成上手臂A(upperA)和下手臂A(lowerA)的程式，再註解掉身體的程式，讓下手臂能夠正常連接上手臂並挪動
