前言
陸陸續續接觸osg有一段時間了. 也陸陸續續寫過很多小demo來做一些基礎的測試, 但是基本沒怎麼用在項目中,有的僅僅是顯示的部分.偶然間羣友就討論起了魔方來,其中一個小夥伴就問魔方的程序怎麼寫, 然後幾個小夥伴就本着無聊,就各自用自己知道的知識寫了一個玩, 我這個是c++osg的,其它的有個是.net的,還有一個是js的,本着學習記錄,說不定以後能回頭再完善些也好
展示
繪製出來的效果是這樣的
實際上爲了方便,將那個魔方可以任意調節節數
#define CUBEFSIZE 9;
功能羅列:
- 單個方塊的選擇
- 魔方面的選擇
- 魔方單個方塊的旋轉.
- 然後就是基本的旋轉等操作,
這裏如果選擇的話,我就讓他成爲白色.
這個是選擇面
接下來讓選擇的小方塊旋轉.
旋轉一個90°
接下來是代碼部分
創建面->創建小方塊->創建魔方 是這個過程.

這個魔方只是一個粗製的版本，很多地方需要雕琢，有很多不完善的地方；
整個魔方的操作，注意一些旋轉操作細節，旋轉中，已經設計好任意點旋轉了，所以整個魔方旋轉基調已經定下了；
關於如何判斷魔方是否已經拼好。實際上，每個方塊的面有一個標識，而魔方中的每個小方塊，也有自己三維座標，到時候，判斷小方塊的面的法向的朝向，是否是一致（奇葩想法…額,實在不行, 三視圖直接判斷顏色…）
以後有機會再完善吧， 有什麼不懂的，可以留言一起討論
