Getting Started

Development Environment

Unity 2019.1.2f1

Running the Demo Application

Open TestWillInk_HTCVive\Assets\Scenes\SampleScene.unity

Attach an HTC Vive or Vive Pro setup.

Press the Play button to start and use the HTC Vive controller's triggers to draw in VR.

By default volumetric ink drawing is enabled. To enable particle ink - select the ParticleInk object in the Scene Hierarchy and enable it in the Inspector.

Technology Guide

The scripts that provide the inking functionality are ParticleInkWriter and VolumetricInkWriter (located in Will.Ink.Unity.dll). Assign one of them to an empty GameObject. Assign another script to the same GameObject to handle controller input. From the second script obtain a reference to the the IInkWriter interface:

    private IInkWriter m_inkWriter;

	void Start()
	{
		m_inkWriter = GetComponent<IInkWriter>();
	}

In the Update method you can call the OnPointerPressed, OnPointerMoved and OnPointerReleased methods in response to controller input:

 	void Update()
	{
        ...

        if (controller.ButtonPressed)
        {
            PointerPoint pp = new PointerPoint(controller.position, controller.pressure, timestamp);

            m_inkWriter.OnPointerPressed(ref pp);
        }

        ...
    }

Please see the TestWillInk_HTCVive sample for details.
