成员(属性)
color : Property|undefined
Gets or sets the Property specifying the
Color of the point.
-
默认值:
Color.WHITE
readonly definitionChanged : Event
Gets the event that is raised whenever a property or sub-property is changed or modified.
disableDepthTestDistance : Property|undefined
Gets or sets the distance from the camera at which to disable the depth test to, for example, prevent clipping against terrain.
When set to zero, the depth test is always applied. When set to Number.POSITIVE_INFINITY, the depth test is never applied.
distanceDisplayCondition : Property|undefined
Gets or sets the
DistanceDisplayCondition Property specifying at what distance from the camera that this point will be displayed.
heightReference : Property|undefined
Gets or sets the Property specifying the
HeightReference.
-
默认值:
HeightReference.NONE
outlineColor : Property|undefined
Gets or sets the Property specifying the
Color of the outline.
-
默认值:
Color.BLACK
outlineWidth : Property|undefined
Gets or sets the numeric Property specifying the the outline width in pixels.
-
默认值:
0
pixelSize : Property|undefined
Gets or sets the numeric Property specifying the size in pixels.
-
默认值:
1
scaleByDistance : Property|undefined
Gets or sets the
NearFarScalar Property used to scale the point based on distance.
If undefined, a constant size is used.
show : Property|undefined
Gets or sets the boolean Property specifying the visibility of the point.
-
默认值:
true
translucencyByDistance : Property|undefined
Gets or sets
NearFarScalar Property specifying the translucency of the point based on the distance from the camera.
A point's translucency will interpolate between the NearFarScalar#nearValue and
NearFarScalar#farValue while the camera distance falls within the lower and upper bounds
of the specified NearFarScalar#near and NearFarScalar#far.
Outside of these ranges the points's translucency remains clamped to the nearest bound.
