OrthographicFrustum

open external class OrthographicFrustum(source)

The viewing frustum is defined by 6 planes. Each plane is represented by a Cartesian4 object, where the x, y, and z components define the unit vector normal to the plane, and the w component is the distance of the plane from the origin/camera position.

const maxRadii = ellipsoid.maximumRadius;

const frustum = new OrthographicFrustum();
frustum.near = 0.01 * maxRadii;
frustum.far = 50.0 * maxRadii;

Types

Companion

external object Companion : Packable<OrthographicFrustum>

Properties

aspectRatio

external var aspectRatio: Double?

The aspect ratio of the frustum's width to it's height.

far

external var far: Double

The distance of the far plane.

near

external var near: Double

The distance of the near plane.

projectionMatrix

external val projectionMatrix: Matrix4

Gets the orthographic projection matrix computed from the view frustum.

width

external var width: Double?

The horizontal width of the frustum in meters.

Functions

clone

external fun clone(result: OrthographicFrustum? = definedExternally): OrthographicFrustum

Returns a duplicate of a OrthographicFrustum instance.

computeCullingVolume

external fun computeCullingVolume(position: Cartesian3, direction: Cartesian3, up: Cartesian3): CullingVolume

Creates a culling volume for this frustum.

equalsEpsilon

external fun equalsEpsilon(other: OrthographicFrustum, relativeEpsilon: Double, absoluteEpsilon: Double? = definedExternally): Boolean

Compares the provided OrthographicFrustum componentwise and returns true if they pass an absolute or relative tolerance test, false otherwise.

getPixelDimensions

external fun getPixelDimensions(drawingBufferWidth: Double, drawingBufferHeight: Double, distance: Double, pixelRatio: Double, result: Cartesian2): Cartesian2

Returns the pixel's width and height in meters.
