一个简单的Java 3D源代码.docx

1、一个简单的Java 3D源代码一个简单的Java 3D源代码 收藏 这段源代码实现了在一个窗体中显示一个场景；以一个棋盘格做的地面，在地面上浮着一个蓝色的球体，在场景中有一个环境光和一个直射光，实现了用鼠标全角度的观察场景的功能。从某种意义上来说这的确实现了一部3D游戏最原始的框架。代码是照着Killer Game Programming in Java一书中关于3D游戏制作的那部分写的，由于此书是英文版的据说在国内也买不到中文翻译版的，看得很费力，本人英文不好。只能慢慢的研究书中的源代码。下面说明下源代码的文件功能GameMain.java - 程序的入口。ScreenManager.Jav

2、a - 实现一个很简单的窗体类从JFrame派生，目前只返回一个窗体，以后可能实现最复杂的功能。WrapCheckers3D.Java - 实现一个简单的3D场景类，能实现一个简单的鼠标操作。CheckerFloor.Java - 实现一个国际象棋般的棋盘格做来场景中的地面。ColouredTile.Java - 派生自Shape3D类，能实现一个正方体平面，用来为CheckerFloor类实现棋盘格GameMain.Java1.importjava.awt.event.WindowAdapter; 2.importjava.awt.event.WindowEvent; 3.4.importj
