3Pipe-Viewer

3Pipe - Viewer

The Viewers

Multiple views (actually 3) of the same scenegraph
synchronised cameraposition and -orientation
synchronised swap-buffer
modifiable camerageometrics (widthangle, heightangle, overlap)
views can be rendered on different displays (speedup on multi-pipe systems)
mouseevents that occur in any display are translated correctly
changes (other than camera) in the scenegraph are shared via Share3D
multiple viewersets (on different machines) can be connected over network via Share3D

Share3D

old:

sharing of fields
support of MolecularInventor
WebFunctions

changes:

new: connectivity via named-pipes for local scenegraph sharing
new: sharing a local 'graph-state' for synchronising
new: sharing of inserting, deleting and replacing of nodes (only on Share3D clients, server doesn't upadte scene-graph)
supressed support of MolecularInventor (because of compatibility and versioning problems)

todo:

implement node-manipulations at serverside
concurancy-control (eg: different users manipulate camera)
watchdog for deadlocks (at the moment, they can be delocked by sending Xevents to the viewers, eg: moving the mouse)
support MolecularInventor latest Version ???

remarks:

Jack's Pen node only works in the middle viewer.

api of HvManager (main viewer):

SoMFString url;            // url for webfunctions
SoSFString server;         // server-address
SoSFInt32  id;             // session id
SoSFBool   autoConnect;    // automatically connect to servers ?
SoSFBool   monitor;        // monitor some performance statistics
SoMFString pipes;          // list of named-pipes to comunicate to client viewers
SoSFBool   webButton;      // show the web button ?

api of HvManagerP (client viewers):

SoSFString pipe;           // name of input pipe (from main viewer)
SoSFBool   monitor;        // monitor some performance statistics

tsMipTexture2

This is a extension of inventor's SoTexture2 wich supports user defined MipMaps.

api:

SoMFString filenames;      // MipMap textures
SoSFEnum   wrapS;          
SoSFEnum   wrapT;          
SoSFEnum   model;          
SoSFColor  blendColor;
