Field Detail

blendOption

@JsProperty
public Number blendOption

The billboard blending option. The default is used for rendering both opaque and translucent billboards. However, if either all of the billboards are completely opaque or all are completely translucent, setting the technique to BillboardRenderTechnique.OPAQUE or BillboardRenderTechnique.TRANSLUCENT can improve performance by up to 2x. Default: BlendOption.OPAQUE_AND_TRANSLUCENT()

debugShowBoundingVolume

@JsProperty
public boolean debugShowBoundingVolume

This property is for debugging only; it is not for production use nor is it optimized. Draws the bounding sphere for each draw command in the primitive. Default: false

modelMatrix

@JsProperty
public Matrix4 modelMatrix

The 4x4 transformation matrix that transforms each polyline in this collection from model to world coordinates. When this is the identity matrix, the polylines are drawn in world coordinates, i.e., Earth's WGS84 coordinates. Local reference frames can be used by providing a different transformation matrix, like that returned by Transforms.eastNorthUpToFixedFrame(org.cesiumjs.cs.core.Cartesian3). Default: Matrix4.IDENTITY()

Constructor Detail

PointPrimitiveCollection

@JsConstructor
public PointPrimitiveCollection()

A renderable collection of points. Points are added and removed from the collection using add(org.cesiumjs.cs.scene.options.PointPrimitiveOptions) and Collection.remove(T). Performance: For best performance, prefer a few collections, each with many points, to many collections with only a few points each. Organize collections so that points with the same update frequency are in the same collection, i.e., points that do not change should be in one collection; points that change every frame should be in another collection; and so on.

PointPrimitiveCollection

@JsConstructor
public PointPrimitiveCollection(PointPrimitiveCollectionOptions options)

A renderable collection of points. Points are added and removed from the collection using add(org.cesiumjs.cs.scene.options.PointPrimitiveOptions) and Collection.remove(T). Performance: For best performance, prefer a few collections, each with many points, to many collections with only a few points each. Organize collections so that points with the same update frequency are in the same collection, i.e., points that do not change should be in one collection; points that change every frame should be in another collection; and so on.

Parameters:

options - PointPrimitiveCollectionOptions

Method Detail

add

public PointPrimitive add(PointPrimitiveOptions options)

Creates and adds a point with the specified initial properties to the collection. The added point is returned so it can be modified or removed from the collection later. Performance: Calling add is expected constant time. However, the collection's vertex buffer is rewritten - an O(n) operation that also incurs CPU to GPU overhead. For best performance, add as many pointPrimitives as possible before calling update.

Parameters:

options - PointPrimitiveOptions

Returns:

The point that was added to the collection.
