EyeOffset

This page describes the possible content of a CZML document or stream. Please read CZML Structure for an explanation of how a CZML document is put together.

#EyeOffset

An offset in eye coordinates which can optionally vary over time. Eye coordinates are a left-handed coordinate system where the X-axis points toward the viewer's right, the Y-axis poitns up, and the Z-axis points into the screen.

Interpolatable: yes

##Properties

cartesian - Cartesian3

The eye offset specified as a three-dimensional Cartesian value [X, Y, Z], in eye coordinates in meters. If the array has three elements, the eye offset is constant. If it has four or more elements, they are time-tagged samples arranged as [Time, X, Y, Z, Time, X, Y, Z, ...], where Time is an ISO 8601 date and time string or seconds since epoch.

reference - Reference

The eye offset specified as a reference to another property.

epoch - string

The epoch to use for times specified as seconds since an epoch.

interpolationAlgorithm - string

The interpolation algorithm to use when interpolating. Valid values are "LINEAR", "LAGRANGE", and "HERMITE".

interpolationDegree - number

The degree of interpolation to use when interpolating.

forwardExtrapolationType - string

The type of extrapolation to perform when a value is requested at a time after any available samples. Valid values are "NONE", "HOLD", and "EXTRAPOLATE".

forwardExtrapolationDuration - number

The amount of time to extrapolate forward before the property becomes undefined. A value of 0 will extrapolate forever.

backwardExtrapolationType - string

The type of extrapolation to perform when a value is requested at a time before any available samples. Valid values are "NONE", "HOLD", and "EXTRAPOLATE".

backwardExtrapolationDuration - number

The amount of time to extrapolate backward before the property becomes undefined. A value of 0 will extrapolate forever.
