Overview

vhToolkitUnity is the Unity3D Unity rendered version of the Virtual Human Toolkit.  This project integrates several research systems together in order for the user to interact with a virtual human character through usage of text to speech and language understanding. Some of the systems that are integrated into his project are the Smartbody animation system, text to speech engines, and AcquireSpeech.  Unity is a 3rd party proprietary rendering engine and is provided as binary-only with the Virtual Human Toolkit. You can download the free version of Unity here. For changing art assets you need to purchase Unity Pro. vhtoolkitUnity was created using the vhAssets package as a starting point.

Using SmartBody Bonebus Mode

Bonebus mode uses Smartbody as a separate process instead of integrated within Unity.  This is useful if you have Unity Free since Smartbody uses Unity Plugins which is a Pro only feature.

  1. While the Toolkit is running, press 'C'

  2. Click 'Launch SB Bonebus' and the SmartBody window will open

  3. Click 'Bonebus Init Scene' and the  Characters will re-initialize in bonebus mode

If Unity will not Play because you have Unity Free, then click the SmartbodyManager gameobject and disable it before playing.

Developers

Loading VHToolkit Scene

  1. Open Unity
  2. File->Open Project (this may already be done for you if this is the first time you've launched Unity)
  3. On the Open Project tab, click the Open Other button.
  4. Navigate to the VHToolkit Unity Project here: <VHToolkit>\core\vhtoolkitUnity
  5. Click Select Folder

Creating your own Project using the VHToolkit Unity Package

  1. Open Unity
  2. File->New Project
  3. You need 2 Unity Packages to start with.  You'll find all packages here: <VHToolkit>\bin\vhtoolkitUnity.  Copy them to <your project>\Assets. 
  4. First, is the vhAssets package.  This contains common scripts and libraries used in various Virtual Humans applications.  There is a different .unitypackage file for each platform.  
    1. vhAssetsPackage.unityPackage    (Windows)
    2. vhAssetsPackageOSX.unityPackage
    3. vhAssetsPackageIOS.unityPackage
    4. vhAssetsPackageAndroid.unityPackage
  5. Second, is the vhAssets Test Scene.  This contains assets and scripts that will initialize a very basic test scene environment.  This file is:  vhAssetsTestScenePackage.unityPackage
  6. Copy the 2 Unity Packages to this new project.
  7. In Unity, in the 'Project' column, double click on the 2 Unity Packages.
  8. Open Scenes->vhAssetsTestScene
  9. Click Play.  The virtual human should be animating in an idle pose.  Hit 'C' to show a debug menu.  You should be able to control him via the buttons on the debug menu.

These instructions are for both Unity Pro and Unity Free. When there are specific instructions for a particular version, they have been marked as such.

There are differences because Unity Pro uses an .dll version of smartbody, and runs within the process. For Unity Free, Smartbody is launched as a separate process and communicates to Unity via network traffic.

Creating your own Virtual Human

Creating your own Virtual Human has different meanings to different groups.  Some people want to use the existing characters that we supply, but only change certain features like giving them a different voice, or a different colored shirt.  Others groups want to use a different character, but the character was created using a standard character package that we already support (Mixamo, etc).  Others want to use a completely different character with a unique skeleton, etc.   These instructions will attempt to explain the different features and how to customize based on your needs.

The easiest way to use your own Virtual Human is to create a Unity Project using the included .unitypackages as a starting point.  From here, you can add/change features on the default character, or bring in your own and customize using the existing character for reference.
