DATASTREAM SDK

Access real-time Vicon data for feedback and control

Download

A flexible and easy way for users to stream in real time to 3rd party programs and Plug-Ins.

Created for the data streams from Nexus, Blade, Shōgun, and Tracker applications to use with third-party applications and plugins.

Datastream SDK
features

Vicon virtual system

SDK has an associated utility – the Vicon Virtual System (VVS). This utility makes the development process easier by simulating a live Vicon system and streaming data to Vicon Nexus, Tracker, Shōgun, and Blade applications.

Create custom applications

SDK and VVS make it easier to create custom applications by providing greater flexibility and easy access to Vicon data in real time.

This allows you to maximize time and work efficiency during data collection and processing. Additionally, SDK and VVS are available for free to existing customers.

Increased 3rd party compatibility

Vicon provides a flexible and powerful SDK solution that is available in three different formats across multiple operating systems, including Unity and Unreal engines for use in VR applications.

Modeling options

Use the SDK to create models in other packages and languages including; MATLAB, Labview, C++ and .Net

Latency compensation

Whilst Vicon Tracker produces data with the lowest possible latency, game engines add latency before the image gets to the eyes in an HMD and this can impact the sense of immersion. From version 1.8 there is a brand-new API for obtaining data in applications where reducing apparent latency is key, in particular location based VR and VR gaming experiences, by correcting for the delays introduced when the engine renders the image to the VR headset.

  3. For Legacy version please contact Vicon Support

How do I set up my network card?

1. Open the Network and Sharing Center and navigate to Change Adapter Settings. Vicon Vantage/Vero cameras are designated to one port.  For each Vue (or Bonita Video) camera connected, there will be additional network port used.

2. Right click on the proper port and go into the Properties. The Local Area Connection Properties window will open. Make sure only Internet Protocol Version 4 (TCP/IPv4) is selected.

3. Select Internet Protocol Version 4 (TCP/IPv4) from the list and select Properties to assign the proper IP address.

a .Vantage/Vero cameras will have the following IP Address: 192.168.10.1 and Subnet Mask of: 255.255.255.0

b. The first VUE camera will have the following IP Address: 192.168.10.2 and Subnet Mask of 255.255.255.0

c. Any additional VUE cameras the last IP value is incrementally increased by one. For example, the second VUE camera will be 192.168.10.3.

Select OK to close out of the Internet Protocol Version 4 (TCP/IPv4) Properties.  And OK again to close out of the Local Area Connection Properties.  This will make sure all changes have been saved.

4. Feel free to rename the network port so it is easily identifiable. Such as ViconMX, VUE1 or VUE2

Datastream SDK 1.8.0

Abstract

File Name: ViconDataStreamSDK_1.8.0_105615h.zip

Vicon DataStream SDK 1.8.0 (Software Development Kit).

The Vicon DataStream Software Development Kit (SDK) allows easy programmable access to the information contained in the Vicon DataStream. The function calls within the SDK allow users to connect to and request data from the Vicon DataStream.

DataStream SDK 1.8.0 incorporates many changes, the most significant of these is a new “Retiming API”. This allows for client applications to request estimated data in non-blocking fashion. i.e. data is returned immediately rather than waiting for a fresh frame. This means that perceived latency is reduced – ideal for VR. Additionally, a small amount of additional prediction can be added to allow the estimate to be predicted into the future to account for rendering delays in game engines.

The source package has been updated and is now included within this distribution under an MIT license, allowing for unlimited use and redistribution of the SDK, whilst limiting liability.

New plugins for Unity 3d and Unreal Engine are now available that take advantage of this new API.

New documentation, using Doxygen is provided.

Requirements

Windows x86 or x64 Linux x86 or x64 OSX 10.11

Blade 3.x, Tracker 3.x, Nexus 2.x *Some methods may not be available to all applications.

4. Launch LabView 2017 (64bit)

5. Select Create Project

6. Double click Blank Project

7. Save your Project in the C:\Users\Public\Documents\08 ThirdParty Software\Labview\LabviewProjects folder created in Step 2

8. In the Project select File > New VI

9. In the New pop-up Window select Blank VI

10. In the Block Diagram Panel, right mouse click > select Connectivity > .NET > Constructor …

11. Place the .NET Constructor in the Block Diagram
