public class SoPreferences
extends java.lang.Object
```
Manages Open Inventor configuration parameters.
Open Inventor maintains a configuration database that stores information about the Open Inventor "environment". The Open Inventor environment contains configuration parameters and their values.

Setting configuration parameters
There are several ways that configuration parameter values are set into the Inventor configuration database:

Configuration files:
Open Inventor Java uses a resource file named com.openinventor.inventor.properties if it is located in your CLASSPATH. You can find this file (com.openinventor.inventor.properties) in the directory $OIVJHOME/properties and modify it to fit your needs. You can copy it to another location, provided that you set your CLASSPATH to point to it.
The configuration parameters specified in the configuration files are set into Open Inventor's configuration database.
The configuration file format is simple. You specify environment name-value pairs, one per line. Values are defined with a left part (the key) and a right part (the value affected), separated with the '=' character.
```
 # comment
 
 # NAME1 and NAME2 are defined and associated
 # with value1 and value2 respectively.
 NAME1=value1
 NAME2=value2
   
 
```
NOTE: Each property defined in this file overrides the environment variable of the same name during the execution of your program. For instance, if a property OIVJHOME is defined, it overrides the environment variable $OIVJHOME. On the other side, they are overridden by the System properties, ie when you use the -D option of the java command line.

Using SoPreferences methods:
setValue(String, String) sets a configuration parameter in the Open Inventor configuration database. As this value is set in memory, it is local to the application process and can only be retrieved using getValue(String).

Querying configuration parameters To query a specific configuration parameter, use the method getValue(String) which returns the value of the specified configuration parameter in the Open Inventor configuration database.
SoPreferences also provides convenience methods for querying specific data types and providing a default value, e.g.,
```
 
        int numFiles = SoPreferences.getInteger( "NUM_FILES", 1 );
 
```
requests the value of an integer-valued configuration parameter and returns the default value 1 if this parameter has not been specified.

Other
The SoPreferences configuration mechanism is not restricted to Open Inventor parameters. Applications are welcome to use it for their own parameters if appropriate.

```
public static final java.lang.String IVVR_DELAY_RENDER
```
    Sets the VolumeViz delayedRendering flag.
    When this flag is TRUE, VolumeViz drawing nodes (e.g. SoOrthoSlice) are considered "transparent" objects by Open Inventor. They may be delayed (until after all opaque objects) and/or sorted according to the current transparency type (see SoGLRenderAction). This may result in a more correct image if there is opaque geometry intersecting the volume. However delayed/sorted rendering may slightly decrease performance. For compatibility with earlier versions of VolumeViz the default is FALSE. This flag may also be set using com.openinventor.volumeviz.SoVolumeViz#setDelayedRendering(boolean).

    Although in most cases the SEGY reader can automatically detect when the number of traces per line in a SEGY file is not uniform, in some cases it cannot. You can set this environment variable to request the use of a more sophisticated file parsing algorithm. However, be aware that the initialization for file reading will take longer when this environment variable is set.

  - IVVR_USE_TEX3D
```
public static final java.lang.String IVVR_USE_TEX3D
```
    Controls when VolumeViz will use OpenGL 3D texturing.
    All boards that report OpenGL version 1.2 or higher are required to support 3D texturing and will render the correct image. However on some boards (e.g. GeForce2) this support is not hardware accelerated and may be very slow. By default VolumeViz tries to detect this situation and automatically disable use of 3D textures, but there are cases where it is desirable to use 3D textures even if they are slow. In these cases set IVVR_USE_TEX3D to 1. Valid values are: - 0 = Never : Do not use 3D textures (even when available) - 1 = Always : Use 3D textures if supported in hardware or software - -1 = WhenFast : Use 3D textures only if supported in hardware (DEFAULT) On some boards, e.g. ATI, WhenFast is the same as Always because we can't reliably detect how 3D textures are implemented.

    Constant Field Values
  - OIV_PBUFFER_ENABLE
```
public static final java.lang.String OIV_PBUFFER_ENABLE
```
    Affects SoOffscreenRenderer. Set to zero to disallow use of Pbuffers. The OpenGL Pbuffer extension allows accelerated rendering to off-screen memory. The SoOffscreenRenderer class will automatically use a Pbuffer (if possible) for rendering. In case of problems using Pbuffers, this environment variable may be used. Note: If Pbuffers are disallowed, OpenGL does rendering in software. This gives low performance and OpenGL extensions will often not be available. In general the image may not match the on-screen image simply because a different renderer is being used. However, the lack of OpenGL extensions can cause the offscreen image to differ signficantly. Following are some of the features that depend on OpenGL extensions: Open Inventor correct transparency, VolumeViz 3D textures, FXViz shadowing and bump mapping.

```
    By default in Open Inventor 3.1, all the geometry nodes of a particular class share a single class mutex. This reduces the number of mutexes needed and does not impose any penalty once the geometry is render cached. If geometry cannot be render cached, it may be better to use per-node mutexes by setting this variable to "0" (zero).
