Namespace Unity.Geospatial.HighPrecision

Classes

HPMath

Mathematics methods used for easily converting data between geodetic formats and Unity default expected formats.

HPNode

High Precision node allowing to get its local and universe position in double precision.

HPRoot

The HPRoot determines how the universe space will be converted into world space. It defines the coordinate in universe space which corresponds to the position of the GameObject, in world space.

The HPTransform is the High-Precision Framework's primary class. It acts very similarly to an ordinary transform, however its position is in 64 bit precision rather than being in 32 bit precision. The HPTransform can be used with or without an HPRoot parent. However, in order to truly benefit from the 64 bit precision, it should be the child of an HPRoot.

LocalCoordinateSystem

The LocalCoordinateSystem component causes any HPTransform to be defined as the center of interest within the universe space. This will maximize rendering precision around this object by essentially keeping it in the center of the scene. For many applications, the camera or the player makes for a good candidate as the origin HPTransform.

This component is meant as an example of how to implement a very simple dynamic rebasing scheme. However, many other schemes can and should be considered, such as rebasing only when getting a predefined distance from the origin or event triggered rebasing when the user performs an action.

MathExtension

Extend Unity mathematics structs.

MatrixExtension

Extension methods for Unity Matrix4x4.

Structs

DoubleBounds

Represents an axis aligned bounding box with values stored as doubles.

DoublePlane

Representation of a plane in 3D space storing values as doubles.

SerializableDoubleBounds

This struct should only be used for serialization purposes within Unity, either in MonoBehaviours, such that it can appear in the inspector, or for JSON serialization. For any purpose that does not require serialization, please use DoubleBounds. Cast as quickly as you can to the DoubleBounds struct which is immutable.

Enums

HPNode.ScaleTypes

The type of scale that the HPNode's current configuration allows. When it is a leaf node, it will accept non-uniform scales. Otherwise, it will only apply a uniform scale.
