Properties

displayName

abstract val displayName: String

This projection's display name.

is2D

open val is2D: Boolean

Indicates whether this projection is a 2D projection.

isContinuous

open val isContinuous: Boolean

Indicates whether this projection is continuous with itself horizontally.

projectionLimits

open val projectionLimits: Sector?

Functions

cartesianToGeographic

abstract fun cartesianToGeographic(ellipsoid: Ellipsoid, x: Double, y: Double, z: Double, offset: Double, result: Position): Position

Converts a Cartesian point to a geographic position.

abstract fun cartesianToLocalTransform(ellipsoid: Ellipsoid, x: Double, y: Double, z: Double, result: Matrix4): Matrix4

geographicToCartesian

abstract fun geographicToCartesian(ellipsoid: Ellipsoid, latitude: Angle, longitude: Angle, altitude: Double, offset: Double, result: Vec3): Vec3

Converts a geographic position to Cartesian coordinates.

geographicToCartesianBorder

abstract fun geographicToCartesianBorder(ellipsoid: Ellipsoid, sector: Sector, numLat: Int, numLon: Int, height: Float, origin: Vec3?, offset: Double, result: FloatArray): FloatArray

geographicToCartesianGrid

abstract fun geographicToCartesianGrid(ellipsoid: Ellipsoid, sector: Sector, numLat: Int, numLon: Int, height: FloatArray?, verticalExaggeration: Double, origin: Vec3?, offset: Double, result: FloatArray, rowOffset: Int, rowStride: Int): FloatArray

geographicToCartesianNormal

abstract fun geographicToCartesianNormal(ellipsoid: Ellipsoid, latitude: Angle, longitude: Angle, result: Vec3): Vec3

geographicToCartesianTransform

abstract fun geographicToCartesianTransform(ellipsoid: Ellipsoid, latitude: Angle, longitude: Angle, altitude: Double, result: Matrix4): Matrix4

intersect

abstract fun intersect(ellipsoid: Ellipsoid, line: Line, result: Vec3): Boolean

Computes the first intersection of a specified globe and line. The line is interpreted as a ray; intersection points behind the line's origin are ignored.
