Release
7.1
This document provides information about the new features and improvements in the most recent releases of BS Contact 7.1. Indepth technical documentation is available in the BS SDK.
The node BSCollaborate is for managing user events such as Avatar movement, Login/Logout events and Chat messages.NetConnection
exposedField SFBool enabled TRUE #Enable or disable the connection exposedField MFString address "localhost" #Address of the server to connect exposedField SFInt32 port 0 #Port number from the server eventIn SFInt32 protocol 3 #Protocol number to use eventOut SFBool isActive FALSE #Event for established connection to server
The node EventStreamSensor is like a proto or script interface. It can handle many variables for sending and reciving events.BSCollaborate

To define special physicalized shapes with a high poly model and a simpler physic shape, BS Contact 7.1 provide the node PhysicShape.PhysicsTransform

You can customize the physics engine and set some global threshholds with the physics node PhysicsInfoPhysicsShape

The X3D node MovieTexture also supports SWF files. The new flag exposedField SFBool stream FALSE for MovieTexture nodes allows the direct download by the movie renderer. With the default stream FALSE http urls are first downloaded to the cache.
A Cube with a YouTube Flash Movie
The node FlashMovieTexture renders SWF files or streams to a texture and allows interaction with the embedded Adobe Flashplayer. With the option transparent=true Flash movies can have background color key transparency. Test for a transparent Flash Movie
The xml-parser now supports the usage of collada digital asset exchange (dae) files. This example demonstrates different transform nodes applied onto cylinder shapes.
Collada content authors are now able to inline their collada-geometry in a X3D or VRML file. DAE files can simply be inlcuded using a regular Inline node.
The BS Contact 7.1 release makes it even simpler to utilize the visualization software BS Contact.
A new installation mechanism enables the user to install the Bitmanagement viewer (plug-in) and stand-alone application instantly
and simultaneously. Under Windows XP an application can be started by a simple click on a link of the application and can then be
used interactively, without any previous knowledge of how to install the application.
Automatic Installation of BS Contact 7.1
The Text node in USE_TEXTURE mode is improved for extended UTF-8 character ranges.
The Particle node supports the new field for emitting particels in local or global coordinates.
exposedField SFBool emitLocal TRUENew scripting functions:
Browser.saveNode(...) Browser.openFileDialog(...)New member functions for nodes : Introspection of node interfaces
int sfnode.getNumFields() # get number of fields mfstring sfnode.getFieldInfo(int) # get information for field value sfnode.getFieldDefault(int) # get the PROTO default field value sfnode.setEventIn(eventInNameString,value) # set an event in by name and field value
node= textureNode.createPixelTexture(..)
New Stereo Modes: INTERLACED_VERTICAL INTERLACED_HORIZONTAL TRIDELITY
For the DX7 Render DXT1 DXT3 and DXT5 dds texture are now treated as having alpha like in DX9.
Texture nodes are supporting an additional field:
eventOut SFBool isFlipped
This flag indicates if the internal texture image layout is vertically flipped,
and can be used by shaders to adopt the texture coordinates.
New url prefixes install: and cache:
New getOption values: languageENG languageNative language
New option for get and set UI-LANG for setting the Contact translation file.
Extensions for the Object node
Extensions for the DrawOp node
TreeGroup now updates the children field on add/remove children.
