NOTE: We recommend that you uninstall all previous versions of Java 3D before installing this version.

### System Requirements

The 1.5.1-beta2 version of the Java 3D API has been released for Solaris (both sparc and x86/amd64), Linux (both x86 and amd64), Windows (both x86 and amd64), and Mac OS X (both PPC and x86).

#### Solaris Sparc

The 1.5.1-beta2 version of Java 3D for Solaris SPARC requires the following:

- JDK 1.5.0 or later from Sun Microsystems: http://java.sun.com/j2se/
- Solaris 9 or later
- Frame Buffer with OpenGL 1.3 support or better (XVR-600, XVR-1200, Expert3D, etc.). A frame buffer with OpenGL 1.2 support will work, but with reduced texture mapping functionality.
- OpenGL 1.3 for Solaris or later. To find your current version, use: "`pkginfo -l SUNWglrt`". OpenGL for Solaris can be obtained at: http://www.sun.com/software/graphics/opengl/

#### Solaris x86

The 1.5.1-beta2 version of Java 3D for Solaris x86/amd64 requires the following:

- JDK 1.5.0 or later from Sun Microsystems: http://java.sun.com/j2se/
- Solaris 10 or later
- NVIDIA Frame Buffer with OpenGL 1.3 or later

#### Linux

The 1.5.1-beta2 version of Java 3D for Linux (x86 or amd64) requires the following:

- JDK 1.5.0 or later from Sun Microsystems: http://java.sun.com/j2se/
- Graphics adapter with driver that supports the GLX extension: GLX 1.3 or later and OpenGL 1.3 or later. A graphics adapter with OpenGL 1.2 support will work, but with reduced texture mapping functionality.

#### Windows

The 1.5.1-beta2 version of Java 3D for Windows 2000, Windows XP (x86 or amd64), or Windows Vista requires the following:

- JDK 1.5.0 or later from Sun Microsystems: http://java.sun.com/j2se/
- Windows 2000, Windows XP, or Windows Vista
- Support for either OpenGL or DirectX as shown below.

OpenGL version

The (default) OpenGL renderer of Java 3D requires OpenGL 1.3 or later, available from your graphics card manufacturer.

DirectX version

The (optional) DirectX renderer of Java 3D requires DirectX 9.0 or later, which is available from Microsoft at: http://www.microsoft.com/windows/directx/ . The DirectX version of Java 3D is selected by setting the "`j3d.rend`" system property to "`d3d`", for example:

`java -Dj3d.rend=d3d ClassName`

NOTE: The DirectX version of Java 3D is used if a suitable version of OpenGL cannot be found. Note also that DirectX is chosen by default on Windows Vista systems with an ATI graphics card (due to ATI driver bugs).

#### Mac OS X

The 1.5.1-beta2 version of Java 3D for Mac OS X (PPC or x86) requires the following:

- JDK 1.5.0 or later from Apple: http://developer.apple.com/java/download/
- Java Binding for OpenGL (JOGL), available at: https://jogl.dev.java.net/
  you can click here for a direct link to the download folder
- Apple OS X 10.3 or later (10.4 or later is required for Intel-based Apple systems)
- Support for OpenGL 1.3 or later

### Improvements in 1.5.1-beta2

#### Enhancements

- Windows Vista Support
- Pack200 Support for Java Web Start Applications
- Logging Framework
- Added support for JNLPAppletLauncher (will be available shortly)

### JOGL Rendering Pipeline

A JOGL rendering pipeline, as described in issue 229, is now available on all supported platforms, including Apple Mac OS X (x86 or PPC). The easiest way to run Java 3D applications using the JOGL pipeline is via Java Webstart from your browser (with no setup required). Click here to run a Java 3D example program from your browser via the JOGL pipeline. These examples will use JOGL on Mac OS X and the native OpenGL pipeline on all other platforms.

The JOGL renderer is the default on Mac OS X. You can select the JOGL renderer on other platforms by setting the "`j3d.rend`" system property to "`jogl`", for example:

`java -Dj3d.rend=jogl ClassName`

You will need to download JOGL and install it into the JRE along with the Java 3D jar files (or include it in your PATH/CLASSPATH).

NOTE: You must install both Java 3D and JOGL into the JRE, or else you must install neither Java 3D nor JOGL into the JRE. If you install Java 3D into the JRE and put JOGL on your CLASSPATH, the JoglPipeline will fail to find the JOGL classes.
