USING 3D DATA
SENDING DATA TO A CLIENT APPLICATION
There are different methods for communicating to a host application or system
depending on your needs. Unless you have specific reasons for not doing so,
WorldViz recommends using our VRPN Ethernet-based network protocol. The
alternatives are shared memory (for when rendering with Vizard on the same
machine), RS-232 serial communication, or connection to a Motion Builder server.
All methods use the "Talk" toggle to turn the connection on and off. You must have
talk active to send data to a client application. The talk button is automatically active
while the PPT Studio is under 3D view. You can switch it off by clicking the talk
button under 2D view.
VRPN 7 (Recommended)
The Virtual-Reality Peripheral Network (VRPN) is the preferred method of connecting
to your host application. The Ethernet-based network connection is versatile and
offers lower latencies than serial communication, especially for large numbers of
markers and high update rates. If your host application does not currently support a
VRPN connection, adding this functionality is straightforward. Both VRPN6 and VRPN7
are supported.
By default, your PPT will output in VRPN7 format. You can easily change this
configuration by selecting the desired output plugin as found in the Configuration
Pane.
