Pygame_openGL(初)

該怎麼去用Python去繪圖一個3D世界呢，終於來到這一天用CODE繪製3D畫面
pythonprogramming.net
先照哥的code跑一遍
得到哥的畫面呢，假設實現minecraft創世神有可能嗎之類的
就開始找到目前為止的資料吧
初步構想呢我想為這個遊戲新增什麼東西呢
今天共新增了
這些在網路上超少，或許我對opengl關鍵字不夠熟悉關係，
不過還是可以透過其他語言控制opengl的code從其中找出關聯性
貼圖紋理和為這個世界加入音效，和顯示文字之類的東東 直接來上代碼吧 改裝後!用滾輪來調控速度
預計

徒手打造一個mmorpg，所以呢我們接下來我們可以來產生一個地面，讓角色在cube行走，已經掌握貼圖後，我們可以再加入其他更多模型3dsmax骨架之類的，算了扯遠了，話說在座標還分很多種世界座標，視窗座標等等 終於了解數學不好不能寫遊戲惹，又不是說要編寫一個引擎(或許可能?!)，光源阿之類的粒子特效，總而言之，有這個demo我們只要再加入碰撞效果，創建地圖的話我們就可以打造一個類似mmorpg，day1慢慢啃

個別物件進行翻轉的時候應該用投影矩陣類似的東西，有趣的是發現原來遊戲世界的周圍
是可能用
