【转自岩屋】Java 3D 已经开源了

【写在前面】Java3D的开源似乎昭示了SUN希望其产品继续崛起的决心，但是似乎早已是大势已去，这一步来的已经太晚了，PV3D已经在开源的世界左右逢源了。

但是换一个角度讲：JAVA3D的开源对于PV3D的开发人员又是一大喜讯，我想技术是共通的，也许JAVA3D里做的好的技术会被大家借鉴到PV3D里面，使得这个小规模团体的开源软件做的更好，更大。

Java 3D 已经开源了

Javae 3D API是作为复杂三维图形和声音渲染系统的接口的一系列层次的JAVA类的统称。开发员可以用Java3D开发创建和操纵3D图形对象的高端应用。
Java3D 项目由多个子项目组成主要包括:j3d-core(Java3D API的核心), vecmath(3D矢量数学包)与j3d-core-utils(Java3D核心utilitie)，Java3D VRML97 Loader等，现在j3d-core和vecmath已经开源了，将采用GPLv2 with the Classpath exception许可授权。

FourByFouris a three dimensional game of tic-tac-toe on a 4x4x4 cube.
HelloUniverse a simple rotating cube.

PrintCanvas3D a program to test off-screen rendering and printing.
QueryProperties displays a list of 3D properties in a text panel.

Advanced Texture Mapping Examples

The following examples use advanced texture mapping features. They should run on most graphics cards, although they may not run on some older cards:

DOT3Demo a bump mapping example.
TextureImageNPOT a non-power-of-two texture example.

Sound Examples using JOALMixer

The following examples use JOALMixer to render Java3D Sound nodes. You will need a sound card and speakers or headphones in order to hear the sound for these examples. JOALMixer is supported on Windows, Linux, and MacOSX.

BackgroundSoundTest a simple background sound test.
PointSoundTest a simple point sound test.

Programmable Shader Examples

Programmable shader examples using OpenGL's GLSL shading language. Note that the following examples require a shader-capable graphics card (for example, an NVidia 6600 or ATI X200).

EnvironmentMappingGLSL an environment mapping example.
ObjLoadGLSL an example that loads in a .obj file and applies a shader.

PhongShadingGLSL a per-pixel lighting (Phong shading) example.
ShaderTestGLSL a program illustrating multiple shaders
