1、JME(java Monkey Engine) 学习笔记 bianerJME是一个高性能的3D图形API，采用LWJGL作为底层支持。它的后续版本将支持JOGL。JME和Java 3D具有类似的场景结构，开发者必须以树状方式组织自己的场景。JME有一套很好的优化机制，这使得它得运行速度要比Java 3D快很多。 JME(java Monkey Engine)，一个非常棒的Java 3D游戏引擎.通过学习，然后把相关的理解写下来，供有需要的朋友参考。虽然，对于我们来说，无法编写如此优秀的操作引擎。但希望有更多像从事游戏制作、开发的朋友，能提供帮助，开发出让大众喜欢的游戏。希望读者喜欢，希望读者能
2、有所收获。谨以此一系列的学习笔记，送给我最爱的小银猪。希望她快乐、幸福。bianer 2011春Lesson1/*通过SimpleGame建立游戏场景，并显示创建的对象*/public class Lesson1 extends SimpleGame /* * Main method is the entry point for this lesson.
