PlaneSurface Class
A representation of an infinite plane which can serve as a surface for interactions.
Rarely used on its own, but frequently used as an underlying component of ClippedPlaneSurfaces.
While it is uncommon for a PlaneSurface to be used on its own (because few interactable elements can be considered infinite planes), it is quite common for multiple different ClippedPlaneSurfaces to exist on the same plane: consider multiple buttons on a single interactable UI. In such a scenario, many ClippedPlaneSurfaces can be backed by the same PlaneSurface, ensuring that they always remain coplanar regardless of edits to the underlying surface.
Member Enumerations
Enumeration NormalFacing
Used for interaction with flat surfaces, and acts in much the same way as Unity’s Plane.
Backward | Normal faces along the transform's negative Z axis |
Forward | Normal faces along the transform's positive Z axis |
Properties
NormalFacing Facing[Get]
Gets or sets the direction (NormalFacing.Forward or NormalFacing.Backward) for this plane.
bool DoubleSided[Get]
Determines whether this plane is double-sided.
If true, this plane can be interacted with from either side; otherwise, the plane is only considered to exist if perceived from the direction of its normal.
Vector3 Normal[Get]
Returns either the forward direction or the backward direction depending on whether Facing is NormalFacing.Forward or NormalFacing.Backward, respectively.
Bounds Bounds[Get]
Implementation of IBounds.Bounds; for details, please refer to the related documentation provided for that property.
Fields
Transform Transform[Get]
Implementation of ISurface.Transform; for details, please refer to the related documentation provided for that property.
Member Functions
bool ClosestSurfacePoint
( in Vector3 point,
out SurfaceHit hit,
float maxDistance )
Implementation of ISurface.ClosestSurfacePoint(in Vector3, out SurfaceHit, float); for details, please refer to the related documentation provided for that property.
bool Raycast
( in Ray ray,
out SurfaceHit hit,
float maxDistance )
Implementation of ISurface.Raycast(in Ray, out SurfaceHit, float); for details, please refer to the related documentation provided for that property.
Plane GetPlane ( )
Gets a Unity Plane representation of the mathematical plane represented by this PlaneSurface.
void InjectAllPlaneSurface
( NormalFacing facing,
bool doubleSided )
Injects all required dependencies for a dynamically instantiated PlaneSurface; effectively wraps InjectNormalFacing(NormalFacing) and InjectDoubleSided(bool).
This method exists to support Interaction SDK's dependency injection pattern and is not needed for typical Unity Editor-based usage.
void InjectNormalFacing
( NormalFacing facing )
Sets the NormalFacing value for a dynamically instantiated PlaneSurface.
This method exists to support Interaction SDK's dependency injection pattern and is not needed for typical Unity Editor-based usage.
void InjectDoubleSided
( bool doubleSided )
Sets whether a dynamically instantiated PlaneSurface should be interactable from both sides.
This method exists to support Interaction SDK's dependency injection pattern and is not needed for typical Unity Editor-based usage.
