Unreal Engine Project: Sensorimotor Lab

Version: v2.0.1
Author: Roland Bruggmann

Description

Screenshot of Project Content

A project based on UE Display Cluster template aka ‘nDisplay’ providing with Institute of Sport Science ISPW related maps, more precise for the sensorimotor laboratory with its five sided CAVE. The laboratory integration is enabled by a messaging layer which is used to interact with an enterprise service bus ESB or the laboratory’s experiment management system repectively. This project was elaborated in TPF approved project ‘Distributed Game Engine DGE’ and subsequent projects.

3. Maps

3.1. Map ISPW Cave 3D Demo

The map ISPW_Cave_3D_Demo which is a copy from plugin ISPW is intended to demonstrate the real-time rendering of 3D content in mono but also in stereo mode and the perception of the same using shutter glasses in the ISPW SenorimotorLab CAVE:

3.2. Map ISPW Cave 360DegVideo

The map ISPW_Cave_360DegVideo which is a copy from plugin ISPW provides with lab integration enabled by a newly developed messaging layer which allow VR-objects to be controlled by the lab’s experiment management system and CAVE-specific content to be rendered:

4. Display Cluster

4.1. nDisplay Configurations

Edit nDisplay config file *.cfg (host IPs, master etc.) using a text editor of choice. For further information see plugin ‘ISPW’.

4.2. Packaging

Brief instruction for packaging a shipping build (cp. Unreal Engine Documentation, Packaging Projects):

  1. In Project Settings set ISPW_Cave_360DegVideo as Game Default Map
  2. File > Package Project > Build Configuration > Shipping
  3. File > Package Project > Windows (64-bit)
  4. Point to a folder of your choice

In the folder of your choice a folder ‘WindowsNoEditor’ is created containing the executable file (*.exe).

4.3. nDisplay Launcher

Brief instruction to run an ISPW-CAVE game unwrapped locally on your machine (cp. Unreal Engine Documentation, nDisplay Quick Start):

  1. Find and launch nDisplay Listener and nDisplay Launcher (folder ‘C: \Program Files \Epic Games \UE_4.26 \Engine \Binaries \DotNET’ or similar)
  2. In nDisplay Launcher, Tab ‘Launcher’, List of Applications > Click Button ‘Add’: Point to the shipping build executable ‘*.exe’ in folder ‘WindowsNoEditor’
  3. In nDisplay Launcher, Tab ‘Launcher’, Config Files Dropdown > Click Button ‘Add’: Point to a Display Config, e.g., ‘\WindowsNoEditor \SensorimotorLab \Content \DisplayClusterConfigs \Dev \CAVE-5_-_3DMode-Off_-_Camera-Static_-_Projection-Simple_-_unwrap.cfg’
  4. Click Button ‘Run’

4.3.2. Test Pattern

To load a test pattern make use of Cluster Events (cp. Unreal Engine Documentation, Test-Patterns).

5. Integration

For testing purpose plugin ISPW provides with Jupyter Notebooks:

Please in folder ISPW/Testing find instructions on how to install Anaconda and setup Jupyter Notebook.
