Description

Renders one or more points in the 3D scene. Each point in the batch has a unique position and an optional color. All points in the batch share the same pixel size. For best performance, avoid creating lots of batches with only a few points each. See the Batching Performance Overview.

Public Methods

Set	Defines the positions of points in a point batch. The points are rendered in the primitive's Reference Frame.
SetCartographic	For convenience. Defines the positions of points in a point batch using Cartographic positions. This is equivalent to converting each position in positions to Cartesian and calling Set.
SetCartographicWithColors	For convenience. Defines the positions and colors of points in a point batch using Cartographic positions. This is equivalent to converting each position in positions to Cartesian and calling Set.
SetCartographicWithColorsAndRenderPass	For convenience. Defines the positions and colors of points in a point batch using Cartographic positions. renderPassHint is provided for efficiency. This is equivalent to converting each position in positions to Cartesian and calling Set.
SetPartial	Updates a subset of positions in a point batch.
SetPartialCartographic	For convenience. Updates a subset of positions in a point batch using Cartographic positions. This is equivalent to converting each position in positions to Cartesian and calling Set Partial
SetPartialCartographicWithColors	For convenience. Updates a subset of positions and/or colors in a point batch using Cartographic positions. This is equivalent to converting each position in positions to Cartesian and calling Set Partial
SetPartialCartographicWithColorsIndicesOrderAndRenderPass	For convenience. Updates a subset of positions and/or colors in a point batch using Cartographic positions. This is equivalent to converting each position in positions to Cartesian and calling Set Partial
SetPartialCartographicWithIndicesOrder	For convenience. Updates a subset of positions in a point batch using Cartographic positions. This is equivalent to converting each position in positions to Cartesian and calling Set Partial
SetPartialWithColors	Updates a subset of positions and/or colors in a point batch.
SetPartialWithColorsIndicesOrderAndRenderPass	Updates a subset of positions and/or colors in a point batch.
SetPartialWithIndicesOrder	Updates a subset of positions in a point batch.
SetWithColors	Defines the positions and colors of points in a point batch. The points are rendered in the primitive's Reference Frame.
SetWithColorsAndRenderPass	Defines the positions and colors of points in a point batch. The points are rendered in the primitive's Reference Frame. renderPassHint is provided for efficiency.

Public Properties

CentralBodyClipped	Gets or sets whether individual points will be clipped by the central body.
DisplayOutline	Gets or sets whether an outline is rendered around each point in the batch.
DistanceDisplayConditionPerPoint	Gets or sets a Distance Display Condition that is evaluated per point in the point batch during rendering. This is different than Display Condition, which is evaluated once for the entire point batch. When `DistanceDisplayConditionPerPoint` is `null`, no per point display condition is evaluated.
MaximumPixelSizeSupported	Gets the maximum pixel size supported by the video card.
MinimumPixelSizeSupported	Gets the minimum pixel size supported by the video card.
OutlineColor	Gets or sets the outline's color.
OutlineTranslucency	Gets or sets the translucency of the outline. Translucency is between `0` and `1`, where `0` is opaque and `1` is transparent.
OutlineWidth	Gets or sets the size, in pixels, of the outline around each point in the batch.
PerItemPickingEnabled	Gets or sets whether individual point indices will be included in the PickResults returned from the Scene's `Pick` method. Each point index that is picked will be returned as a BatchPrimitiveIndex.
PixelSize	Gets or sets the size, in pixels, of each point in the point batch.
SetHint	Gets the primitive's Set Hint. See the Set Hint Performance Overview for selecting an appropriate value to construct the primitive with.
