• Supports three mesh types: triangular prism, quadrangular prism, and cylinder.

• Supports selecting a single feature.

• It has a rotation animation.

• Low performance overhead. Supports thousands of data entries.

OD flowline widget

An OD flowline uses an upward-arching arc to represent a connection.

Key features of this primitive:

• An arc corresponds to one line data entry. The line contains only a start point and an end point.

• The line has a flow animation with directionality. The sign (positive or negative) of the speed in the animation configuration controls the direction.

• There are two flowline types: "vector" and "texture". The "vector" type consists of a baseline with a highlight line overlay and does not require a texture. The "texture" type requires a flowline texture or a symbol texture. The former determines the basic texture of the flowline, and the latter determines the point-like symbols that move along the flowline.

• Low performance overhead. Supports thousands of data entries.

• Uses a transparent material and is not affected by lighting.

• You can specify the baseline thickness to map a numerical relationship in the data.

• Supports selecting a single line.

2D icon widget

A 2D icon represents a point feature in a point sprite-like manner, which means the icon always faces the camera. It is often used to visualize many infrastructure points.

Key features of this primitive:

• You can specify the position, image, size, color, space, type, and quantity relationship for a single icon in the data.

• Supports selecting a single feature.

• It has a breathing animation.

• Not affected by lighting.

• Extremely low performance overhead. Supports tens of thousands of data entries.

Point heatmap widget

The point heatmap widget constructs and renders a heatmap based on the density and values of points. It reflects the macroscopic features of the data and does not support interaction or animation.

Key features of this primitive:

• In areas where points are denser or have higher values, the color is closer to the high-value color and the height is greater.

• Low performance overhead. Supports thousands of data entries.

• It accurately reflects overall macroscopic heat features only with a large data volume. It is not recommended for small or sparsely distributed datasets.

• Not affected by lighting.

General line widget

The general line widget uses polylines to represent line features. It can be used to represent roads, administrative boundaries, and other features at a macro level.

Key features of this primitive:

• You can efficiently update line colors using state data (stateData).

• Low performance overhead. Supports thousands of data entries.

• Uses a transparent material and is not affected by lighting.

• You can specify the thickness and color of individual line segments in the data.

• Supports selecting a single line.

Text Label Component

Billboard labels represent point features as point sprites, which are composed of images and text and always face the camera.

Simple label widget

The simple label widget renders large batches of image-text labels. Unlike the label bulletin board widget that supports only a small number of labels, the simple label widget is used to visualize a large volume of point data.

Key features of this primitive:

• Supports only simple layout configurations. Each label consists of one icon, one line of text, and a background filled with either an image or a solid color.

• You can specify the text, icon, and background image or fill color for each label in the data. The background image and fill color are mutually exclusive. To create a transparent background, set the fill color to 'rgba(0,0,0,0)'.

• Supports selecting a single feature.

• Not affected by lighting.

• Low performance overhead. Supports thousands of data entries.

• Image and text size affect performance. To optimize performance, minimize the image and font sizes.

• Supports GeoJSON and Mapbox Vector Tile (MVT) data sources.

Breathing bubble widget

A breathing bubble uses a flat, ground-level patch to represent a point feature. It is used for indication, decoration, and value mapping.

Key features of this primitive:

• You can specify the radius of a single patch in the data.

• It has a looping sequence frame animation.

• Supports selecting a single feature.

• Low performance overhead. Supports thousands of data entries.

• The number of horizontal and portrait frames must match the sequence frame texture.

Widened fence widget

A widened fence first widens a polygon boundary horizontally and then stretches it vertically. It is mainly used to represent area boundaries.

Key features of this primitive:

• The sides have a transparency gradient and texture animation.

• Low performance overhead. Supports thousands of data entries.

• Uses a transparent material and is not affected by lighting.

• Supports selecting a single feature.

Storage analysis

This widget lets you add spatial widgets to virtual twin objects in a scene, such as the sphere field of view widget and the cone field of view widget.

Viewshed analysis

Viewshed analysis is a type of geospatial analysis that determines the areas directly visible from a specific observation point. It considers factors such as terrain, obstacles such as buildings and trees, and other elements that might affect the line of sight.

Typical applications of viewshed analysis in different fields:

• Urban planning and architectural design: Evaluate the impact of new buildings on the existing visual landscape or assess the scenic value of a specific location.

• Environmental protection: Assess the visual impact on specific geographical features, such as mountains, rivers, and cultural heritage sites.

• Telecommunications: Plan the optimal locations for radio communication towers and other transmission facilities to ensure effective signal coverage.

• Military and security: Determine the best locations for surveillance towers or outposts to maximize monitoring areas and fields of view.

• Tourism planning: Evaluate and optimize the placement of viewpoints or scenic routes to provide the best viewing experience.

Sphere field of view widget

The spatial position of the sphere field of view analysis widget is synchronized with the twin object. It can impersonate a moving target, such as a vehicle, to show its surrounding view obstruction.

Cone field of view widget

Cone field of view analysis assesses the visibility within a conical range between a starting point and a target point.
