Detailed Description

Controls how global geospatial coordinates are mapped to coordinates in the Unreal Engine level.

Internally, Cesium uses a global Earth-centered, Earth-fixed (ECEF) ellipsoid-centered coordinate system, where the ellipsoid is usually the World Geodetic System 1984 (WGS84) ellipsoid. This is a right-handed system centered at the Earth's center of mass, where +X is in the direction of the intersection of the Equator and the Prime Meridian (zero degrees longitude), +Y is in the direction of the intersection of the Equator and +90 degrees longitude, and +Z is through the North Pole. This Actor is used by other Cesium Actors and components to control how this coordinate system is mapped into an Unreal Engine world and level.

ComputeEarthCenteredEarthFixedToUnrealTransformation()

FMatrix ACesiumGeoreference::ComputeEarthCenteredEarthFixedToUnrealTransformation

(

)

const

Computes the transformation matrix from the Earth-Centered, Earth-Fixed (ECEF) coordinate system to the Unreal coordinate system.

The Unreal coordinates should generally not be interpreted as Unreal world coordinates, but rather a coordinate system based on some parent Actor's reference frame as defined by its transform. This way, the chain of Unreal transforms places and orients the "globe" in the Unreal world.

ComputeEastSouthUpAtEarthCenteredEarthFixedPositionToUnrealTransformation()

FMatrix ACesiumGeoreference::ComputeEastSouthUpAtEarthCenteredEarthFixedPositionToUnrealTransformation

(

const FVector &

EarthCenteredEarthFixedPosition

)

const

Computes the matrix that transforms from an East-South-Up frame centered at a given location to the Unreal frame.

The location is expressed as an Earth-Centered, Earth-Fixed (ECEF) position. To use an Unreal position instead, use ComputeUnrealToEastSouthUpTransformation.

In an East-South-Up frame, +X points East, +Y points South, and +Z points Up. However, the directions of "East", "South", and "Up" in Unreal or ECEF coordinates vary depending on where on the globe we are talking about. That is why this function takes a location, expressed in ECEF coordinates, that defines the origin of the East-South-Up frame of interest.

The resulting matrix should generally not be relative to the Unreal world, but rather be expressed in some parent Actor's reference frame as defined by its Transform. This way, the chain of Unreal transforms places and orients the "globe" in the Unreal world.

ComputeEastSouthUpToUnrealTransformation()

FMatrix ACesiumGeoreference::ComputeEastSouthUpToUnrealTransformation

(

const FVector &

UnrealLocation

)

const

Computes the matrix that transforms from an East-South-Up frame centered at a given location to the Unreal frame.

However, the directions of "East", "South", and "Up" in Unreal or ECEF coordinates vary depending on where on the globe we are talking about. That is why this function takes a location, expressed in Unreal coordinates, that defines the origin of the East-South-Up frame of interest.

ComputeUnrealToEastSouthUpTransformation()

FMatrix ACesiumGeoreference::ComputeUnrealToEastSouthUpTransformation

(

const FVector &

UnrealLocation

)

const

Computes the matrix that transforms from the Unreal frame to an East-South-Up frame centered at a given location.

The location is expressed in Unreal coordinates. To use an Earth-Centered, Earth-Fixed position instead, use ComputeEastSouthUpAtEarthCenteredEarthFixedPositionToUnrealTransformation.

In an East-South-Up frame, +X points East, +Y points South, and +Z points Up. However, the directions of "East", "South", and "Up" in Unreal or ECEF coordinates vary depending on where on the globe we are talking about.

Finds and returns the CesiumGeoreference suitable for use with the given Actor.

It searches in the following order:

GetOriginEarthCenteredEarthFixed()

const

Returns the georeference origin position as an FVector in Earth-Centerd, Earth-Fixed (ECEF) coordinates.

Only valid if the placement type is Cartographic Origin (i.e. Longitude / Latitude / Height).

GetOriginHeight()

const

Gets the height of the custom origin placement in meters above the ellipsoid.

GetOriginLatitude()

double ACesiumGeoreference::GetOriginLatitude

const

Gets the latitude of the custom origin placement in degrees, in the range [-90, 90].

GetOriginLongitude()

const

Gets the longitude of the custom origin placement in degrees, in the range [-180, 180].

GetOriginLongitudeLatitudeHeight()

FVector ACesiumGeoreference::GetOriginLongitudeLatitudeHeight

(

)

const

Returns the georeference origin position as an FVector where X is longitude (degrees), Y is latitude (degrees), and Z is height above the ellipsoid (meters).

GetOriginPlacement()

EOriginPlacement ACesiumGeoreference::GetOriginPlacement

(

)

const

Gets the placement of this Actor's origin (coordinate 0,0,0) within the tileset.

3D Tiles tilesets often use Earth-centered, Earth-fixed coordinates, such that the tileset content is in a small bounding volume 6-7 million meters (the radius of the Earth) away from the coordinate system origin. This property allows an alternative position, other then the tileset's true origin, to be treated as the origin for the purpose of this Actor. Using this property will preserve vertex precision (and thus avoid jittering) much better than setting the Actor's Transform property.

GetScale()

If this value is 50, for example, one meter on the globe occupies half a meter in the Unreal world.

TargetEarthCenteredEarthFixed

)

This aligns the specified Earth-Centered, Earth-Fixed (ECEF) coordinates to the Unreal origin.

That is, it moves the globe so that these coordinates exactly fall on the origin. Only valid if the placement type is Cartographic Origin (i.e. Longitude / Latitude / Height). Note that if the provided ECEF coordiantes are near the center of the Earth so that Longitude, Latitude, and Height are undefined, this function will instead place the origin at 0 degrees longitude, 0 degrees latitude, and 0 meters height about the ellipsoid.

Transforms a direction vector in Earth-Centered, Earth-Fixed (ECEF) coordinates into Unreal coordinates.

The resulting direction vector should generally not be interpreted as an Unreal world vector, but rather a vector expressed in some parent Actor's reference frame as defined by its transform. This way, the chain of Unreal transforms places and orients the "globe" in the Unreal world.

Transforms a position in Earth-Centered, Earth-Fixed (ECEF) coordinates into Unreal coordinates.

The resulting position should generally not be interpreted as an Unreal world position, but rather a position expressed in some parent Actor's reference frame as defined by its transform. This way, the chain of Unreal transforms places and orients the "globe" in the Unreal world.

In an East-South-Up frame, +X points East, +Y points South, and +Z points Up.
