WEEEEEEEEEEEK11 牢底坐穿

 WEEK11

-----------------------------------------------------------

WEEK11-1_TRT_again

把上週week10-1放上來

搭出T-R-T程式    

glTranslated(0.3,0.3,0); 掛肩上

    glRotatef(angle++,0,0,1); 轉動

    glTranslatef(0.45/2,0,0); 旋轉中心 放正中心

第一條註解

第三條註解

-------------------------------------------------------------------

WEEK11-2_obj_gundam_again

一條手

maya切割

用maya把其他地方取消掉 export 檔案格式
mtl、obj檔丟進資料夾
