Week12
1.3D Exploration安裝 - 開放Gundam模型
1.1.Save As:OpemGL cpp檔 - SampleApp格式 - 產生cpp檔
2.1. File-New-Project, OpenGL
2.2. Remove main並把gundam_auto.cpp加入文件夾和專案
2.3. Build & Run (有些錯誤就修一下)
#define GL_BGR_EXT 0x80E0
#define GL_BGRA_EXT 0x80E1
///以上2行, 可以解決你在 compile時, 找不到 GL_BGR_EXT 及 GL_BGRA_EXT 的問題
3.1. File-New-Project,GLUT專案
3.2. 先把茶壼做出來(打光) - Week10
3.3. 再加上 glm
3.4. 再加上 貼圖 安裝OpenCV2.1,重開CodeBlocks,Settings-Compiler - Week08
3.5.改變專案的工作執行目錄, . 現在的目錄,將freeglut.dll放在文件夾
3.6.cbp檔用Notepad++打開,dir改為.
3.7.把myTexture()函式放在main()之前
把Diffuse放在專案目錄中
在glutMainLoop()前myTexture("Diffuse.jpg");

glEnable(GL_TEXTURE_2D); ///1. 開啟貼圖功能
GLuint id; ///準備一個 unsigned int 整數, 叫 貼圖ID
glGenTextures(1, &id); /// 產生Generate 貼圖ID
glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖ID
