Unigine.VRHandTracking Class

This class manages the VR hand tracking feature. It allows visualizing the bones basis, velocity and size to check and configure the hands configuration.

Notice

Hand tracking is natively supported only when using the OpenXR backend. This includes any VR device that supports OpenXR hand tracking (e.g., Meta Quest, Varjo, Vive with appropriate runtimes). For varjo and openvr backends, hand tracking requires additional plugins such as LeapMotion Plugin or Ultraleap Plugin.

Refer to this article to properly configure hand tracking in your project and choose the right backend.

VRHandTracking Class

Properties

bool IsAvailable#

The value indicating if hand tracking is available on the active VR device and is supported at runtime.

VRHand HandLeft#

The left hand.

VRHand HandRight#

The right hand.

bool VisualizerEnabled#

Console: vr_hand_tracking_visualizer_enabled
The value indicating if the visualizer for hands is enabled. When set to 1, the engine will draw a simple debug skeleton of the hands, showing bones only. This option requires the Visualizer to be enabled.

The default value is false.

bool ShowBasis#

Console: vr_hand_tracking_show_basis
The value indicating if the visualizer for the coordinate axes (basis) of each hand bone is enabled. This option requires the Hand visualizer to be enabled.

The default value is false.

bool ShowVelocity#

Console: vr_hand_tracking_show_velocity
The value indicating if the visualizer for the velocity vectors of each hand bone is enabled. Useful for debugging motion-based interactions like swipes or throws. This option requires the Hand visualizer to be enabled.

The default value is false.

bool ShowBoneSizes#

Console: vr_hand_tracking_show_bone_sizes
The value indicating if the visualizer for the size of each hand bone is enabled. Displays red spheres representing the size (radius) of each bone, providing a visual reference for the physical dimensions of the tracked hand. This option requires the Hand visualizer to be enabled.

The default value is false.

The information on this page is valid for UNIGINE 2.20 SDK.
