LWJGL 3.3.3 · org.lwjgl.openxr.FBPassthroughKeyboardHands

The XR_FB_passthrough_keyboard_hands extension.

This extension enables applications to show passthrough hands when hands are placed over the tracked keyboard. It enables users to see their hands over the keyboard in a mixed reality application. This extension is dependent on XR_FB_passthrough extension which can be used to create a passthrough layer for hand presence use-case.

The extension supports a single pair of hands (one left and one right hand), multiple pair of hands are not supported.

This extension allows:

Creation of keyboard hands passthrough layer using CreatePassthroughLayerFB
Setting the level of intensity for the hand mask in a passthrough layer with purpose XrPassthroughLayerPurposeFB as PASSTHROUGH_LAYER_PURPOSE_TRACKED_KEYBOARD_HANDS_FB or PASSTHROUGH_LAYER_PURPOSE_TRACKED_KEYBOARD_MASKED_HANDS_FB
