Sony's Extension to VRML2.0

New nodes

Sony_BindSharedNode

is newly introduced to support multiuser functions. This node is used Prototype definition of this node is: 
    PROTO Sony_BindSharedNode [
        field SFNode transformNode NULL
        field SFNode scriptNode NULL
    ] { }
This node is defined to be expanded to nothing so that VRML 2.0 browsers other than Community Place can safely ignore the node.

In the Community Place browser, this node is treated in a special way. A transform node specified for transformNode field of this node is made sharable among clients. In other words, nodes other than those specified in this field are not shared. The field transformNode must be specified and its value must be a Transform node.

If the value of the scriptNode field is not NULL, the value must be a Script node. The Script node's eventIns can be called remotely. You can call sendApplSpecific() or sendApplSpecificWithDist() Java APIs with specifying the target (the first argument) to be the Transform node specified in the transformNode field and eventIn name (the second argument) to be the eventIn names that appear in the Script node.

The third argument of the APIs is a string value, which will be the value of eventIns of the Script node. The eventIns must be of type SFString to accept the values sent using the APIs.

Here is an example:

PROTO Sony_BindSharedNode [ 
  field SFNode transformNode NULL 
  field SFNode scriptNode NULL
] { }

DEF T1 Transform { ... }
DEF S1 Script {
  eventIn SFString IN1
  eventIn SFString IN2
  ...
}

Sony_BindSharedNode { transformNode USE T1 scriptNode USE S1 }

Sony_Appearance

Extends the original Appearance node by putting two new fields: The definition is as follows: 
    PROTO Sony_Appearance [
	field        SFBool   backface         FALSE
	exposedField SFString description      ""
	exposedField SFNode   material         NULL
	exposedField SFNode   texture          NULL
	exposedField SFNode   textureTransform NULL
    ] {
	Appearance {
	    material IS material
	    texture IS texture
	    textureTransform IS textureTransform
	}
    }

Sony_WorldInfo

Sony_WorldInfo is a description of world configurations which is only valid for Sony Community Place Browser. The prototype declaration is following, 
PROTO Sony_WorldInfo [
  field        MFString archive              []
  field        SFInt32  armLength            -1
  field        SFBool   avatarRoom           FALSE
  field        SFInt32  backgroundImageType   0
  field        SFString cpBureau             ""
  field        SFString cpBureauWLS          ""
  field        SFBool   collisionSound       TRUE
  field        SFBool   collisionDisplay     TRUE
  exposedField SFBool   turnButtonAvailable  TRUE
  exposedField SFBool   floatButtonAvailable TRUE
  exposedField SFBool   homeButtonAvailable  TRUE
  field        SFInt32  soundDeviceRate      22050
  field        SFInt32  soundDeviceBits      8
]{}

archive

Specifies an archive which contains files used in this VRML file. These files are extracted and placed in appropriate local directories so that they can be accessed using relative paths from the place where this VRML file is placed. This method reduces the necessary connections during loading the content. For the compatibility with other browsers, these files should be placed in approriate remote directories as well.

The archive itself is created using LHA archiver and must be placed in the same directory as this VRML file is placed.

e.g. 

Sony_WorldInfo {
  archive ["foo.lzh"]
}

armLength

Specifies how far your virtual arm can reach in a world. This parameter is used to decide if an object can be touched. This parameter is specified by "meter".If this is set to -1, the arm length is set to long enough.

e.g. 

Sony_WorldInfo {
  armLength 5
}

avatarRoom

Specifies if an avatar room (for changing avatar color) description file is provided for this world. You can specifiy TRUE or FALSEas the value. If the value is TRUE, a file named avtroom.wrl must be supplied in the same place as this VRML file. The avtroom.wrl is expected to provide the functionality of changing avatar part colors. e.g. 
Sony_WorldInfo {
  avatarRoom TRUE
}

backgroundImageType

Specifies the type of background image format. you can specify one of following numbers.

0
this background image follows VRML2.0 spec.
1
front-URL texture is tiled horizontally and vertically, and the texture never moves while navigation.
2
front-URL texture is tiled horizontally, and the texture moves while navigation (If you turn left, the texture moves right).
e.g. 
Sony_WorldInfo {
  backgroundImageType 0
}

cpBureau

Specifies address and port number of Bureau of the world.

e.g. 

Sony_WorldInfo {
   cpBureau "vsserver.foo.com:5000"
}
or
Sony_WorldInfo {
   cpBureau "12.23.34.45:5000"
}

cpBureauWLS

Specifies address and port number of World Location Server of the world. Also you must specify 'title' in WorldInfo when you use the WorldLocationServer.

e.g. 

Sony_WorldInfo { 
  cpBureauWLS "vsserver.foo.com:6000"
} 
or
Sony_WorldInfo {
  cpBureauWLS "12.23.34.45:6000"
}

collisionSound

If you set this TRUE, Browser will play collision sound when you collide something.

e.g. 

Sony_WorldInfo {
  collisionSound FALSE
}

collisionDisplay

If you set this TRUE, Browser will display red frame when you collide something.

e.g. 

Sony_WorldInfo {
  collisionDisplay FALSE
}

turnButtonAvailableüAfloatButtonAvailableüAhomeButtonAvailable

Specifies availability of Turn, Float, Home button of Community Place Browser. If you set this TRUE, the button is available.

e.g. 

Sony_WorldInfo {
  turnButtonAvailable  FALSE
  floatButtonAvailable FALSE
  homeButtonAvailable  FALSE
}

soundDeviceRateüAsoundDeviceBits

Specifies sound device parameters which Community Place open.

e.g. 

Sony_WorldInfo {
  soundDeviceRate  22050
  soundDeviceBits  8
}
