SpatialInterface provides access to the underlying native functionality through JNI. It handles initialization, destruction, and the execution of various subsystems including:

Physics simulation

Animation

Input (controllers and hands)

Transformation systems

Data model synchronization

This class is typically instantiated and managed by VrActivity or its subclasses, which handle the proper sequencing of method calls throughout the application lifecycle.

Properties

appPtr_ : Long [Get]	Pointer to the native application instance. This is set during initialization and used for all native method calls. Signature var appPtr_: Long
dataModel : DataModel [Get]	The data model associated with this spatial interface. Contains the entity-component data for the application. Signature lateinit var dataModel: DataModel

Functions

applyHapticFeedback ( hand , amplitude , duration , frequency )	Applies the given haptic feedback to both controllers. This method triggers haptic feedback (vibration) on the specified controller, allowing for tactile feedback in response to user interactions. Signature fun applyHapticFeedback(hand: Hand, amplitude: Float, duration: Long, frequency: Float) Parameters hand: Hand Apply haptics to the specified controller hand. amplitude: Float Value between 0 - 1 for strength of haptics. duration: Long Time in nanoseconds for how long the haptic feedback should be applied. frequency: Float Frequency of vibration (in hz).
enableAABBDebugLines ( enabled )	Toggles debug lines for AABB(Axis Aligned Bounding Boxes) around each scene object. This is useful for visualizing the spatial extents of objects in the scene and understanding collision boundaries. Signature fun enableAABBDebugLines(enabled: Boolean) Parameters enabled: Boolean Whether to enable or disable AABB debug lines.
enableInput ( enabled )	Controls whether input (controllers and hands) are enabled. This method can be used to temporarily disable input processing. Signature fun enableInput(enabled: Boolean) Parameters enabled: Boolean Whether input should be enabled or disabled.
setPerformanceLevel ( level )	Set the performance level for both CPU and GPU. This allows developers to control the performance level of the device. Higher performance levels provide better performance but consume more power. Example usage: // Set to boost mode during intensive operations spatial.setPerformanceLevel(PerformanceLevel.BOOST_HINT) // Disable boost by setting back to default (SUSTAIN_HIGH) spatial.setPerformanceLevel(PerformanceLevel.SUSTAIN_HIGH) // Set to sustained low mode to preserve battery life spatial.setPerformanceLevel(PerformanceLevel.SUSTAINED_LOW) Signature fun setPerformanceLevel(level: PerformanceLevel): Boolean Parameters level: PerformanceLevel The performance level to set for both CPU and GPU. Returns Boolean true if the operation was successful, false otherwise.
