Classes

AppBar

Logic for the App Bar. Generates buttons, manages states.

BaseStateModel

Base class for defining state model logic to use in conjunction with the State class Allows for retrieving current state mode and comparing states

Billboard

The Billboard class implements the behaviors needed to keep a GameObject oriented towards the user.

BoundingBox allows to transform objects (rotate and scale) and draws a cube around the object to visualize the possibility of user triggered transform manipulation. BoundingBox provides scale and rotation handles that can be used for far and near interaction manipulation of the object. It further provides a proximity effect for scale and rotation handles that alters scaling and material.

BoundingBoxHelper

The BoundingBoxHelper class contains functions for getting geometric info from the non-axis-aligned bounding box of a GameObject. These functions can be used to align another object to the center of a certain face or the center of an edge of a face... etc. The BoundingBoxHelper static function can be used for a one time calculation. The dynamic functions can be used to obtain boundingcube info on an object's Update loop. Operations are minimized in the dynamic use scenario.

ButtonBackgroundSize

The base layout component for a button or UI elements - easily build UI with Unity Primitives. Helps to create consistency by using values that scale to a designer's 2D layout program. Based on a ratio of 2048 pixels for 1 meter of surface area.

Use case: A designer creates a concept image of UI based on a 2048 artboard. 2048 pixels is a nice resolution for a meter of content, two meters away from the user. The FOV of the HoloLens is about 1 meter wide at 2 meters from the user meaning the designer can assume an image area of 2048 x 1184 pixels at 2 meters from the user. The designer or engineer can take pixel based redlines and create UI at 1:1 scale.

ButtonBackgroundSizeOffset

Scales an object relative the scale of the Anchor Transform Works best when using with Layout3DPixelSize, but not required - See LayoutPixelSize for more info Use Case: Create a button, then add another element who's size should maintain a consistent size relative to the Anchor. Like creating a button background using a Cube and ButtonSize. The add another Cube that is 40 pixels smaller than the background. Event if the background changes size, this element will remain 40 pixels smaller.

ButtonBorder

Use a Unity primitive cube or cylinder as a border segment relative to the scale of the AnchorTransform Use with ButtonSize on the component and the Anchor for consistent results Works best when using with ButtonSize, but not required - See ButtonSize for more info.

ManipulationHandler.HandMovementType

ManipulationHandler.ReleaseBehaviorType

ManipulationHandler.RotateInOneHandType

ManipulationHandler.TwoHandedManipulation

ObjectManipulator.ReleaseBehaviorType

ObjectManipulator.RotateInOneHandType

Describes what pivot the manipulated object will rotate about when you rotate your hand. This is not a description of any limits or additional rotation logic. If no other factors (such as constraints) are involved, rotating your hand by an amount should rotate the object by the same amount. For example a possible future value here is RotateAboutUserDefinedPoint where the user could specify a pivot that the object is to rotate around. An example of a value that should not be found here is MaintainRotationToUser as this restricts rotation of the object when we rotate the hand.
