 HomeWork4製作擺pose機器人

step1:

在maya製作模型(各部位必須分開，不能combine)，並輸出成obj檔

輸出obj檔：File/Export Selection/files of type選擇obj

*點選部位直接匯出就好，不須一個一個刪

Step2:

將obj檔及相對應的html檔放入codeblocks相對的資料夾(為了排放整齊，可創一個資料夾為date放)

Step3:

先將glm.h&glm.cpp&freeglut.dll放入codeblocks的相對應資料夾

開始打程式：

#include <GL/glut.h>

#include <stdio.h>

#include "glm.h"

const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat light_position[] = { 2.0f, 5.0f, -5.0f, 0.0f };

const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };

const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };

const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat high_shininess[] = { 100.0f };///打光

}

*1:在要確定各關節位置時，可使用printf("glTranslatef(%.2f,%.2f,%.2f);\n",dx,dy,dz);和glTranslatef(dx,dy,dz);，方便確定關節該放在什麼座標上

*2:在設定旋轉的中心點時，可先做一個茶壺出來確定中心點在哪
