Module panel

Panel-facing, stable-grab, logical/world conversion, and depth-drag geometry.

Structs

OpenXrPanelFacingOptions

Facing policy and inclusive pitch bounds in radians.

OpenXrPanelGrabState

Retained state that keeps a grabbed panel point stable while it reorients.

OpenXrPanelGrabUpdate

Result of applying a stable-grab facing update.

PanelDepthUpdate

World grab point after optional controller-origin depth translation.

Enums

OpenXrPanelFacingMode

Policy controlling whether panel orientation follows the viewer.

Constants

DEFAULT_PANEL_PITCH_MAX_RAD

Default maximum panel pitch, positive 45 degrees in radians.

DEFAULT_PANEL_PITCH_MIN_RAD

Default minimum panel pitch, negative 45 degrees in radians.

Functions

apply_facing_stable_grab

Applies the selected facing policy while preserving the grabbed world point.

apply_pointer_depth_delta

Projects pointer-origin movement onto the initial ray axis.

apply_yaw_only_stable_grab

Reorients a dragged panel in yaw while preserving the grabbed world point.

face_user_yaw_only

Computes yaw-only orientation whose local positive Z faces the viewer.

face_user_yaw_pitch_clamped

Computes viewer-facing yaw and pitch while keeping roll at zero.

logical_point_to_panel_local

Maps a top-left-origin logical UI point into panel-local metres.

panel_local_to_world

Transforms a panel-local point into world space using the layer pose.

rotate_vec3

Rotates a vector by an OpenXR quaternion.

vec3_from_xr

Converts an OpenXR vector to the crate’s lightweight vector unchanged.

xr_vec3

Converts the crate’s lightweight vector to an OpenXR vector unchanged.
