What's New in TerraExplorer for Web 7.3

Download TerraExplorer for Web 7.3 Release Notes >

Improved Performance

Improved navigation performance (frame rate) especially with medium/low-end machines, when loading a complex project with a significant number of feature layers or heavy 3D mesh layers. Modified feature point caching methods significantly improve navigation performance when flying over massive feature labels.

The new Auto performance/quality mode allows the system to ensure an optimal balance between performance and quality. Adjustments to quality are dynamically performed based on the complexity of the area in view in order to maintain a reasonable frame rate, e.g., when viewing a 3D model, the system may lower the quality slightly to ensure a smooth flight experience.

Volume Classification

New dynamic classification method allows you to associate areas of 3D layers and objects, e.g., mesh layers, with polygonal volume features and their attribute values so you can perform spatial and attribute queries on the mesh layer. The classified sections of the 3D mesh is colorized according to the 3D polygon styling. No pre-processing of the classification and mesh layers is required, so multiple feature layers can classify a single mesh and multiple meshes can be classified by any particular classification feature layer. This feature supports all the new volume classification options, including 3D classification of floors and windows and a 2D polygon buffer area to automatically enlarge the colorized area.

Feature Layer Improvements

• Support for Complex Geometries – TE4W now supports feature layers comprised of complex geometries such as multi-polygons, multi-lines and multi-points, ensuring that all of a loaded layer's sub-features are displayed.
• Support for Query Filters – TE4W now supports feature layer query filters. This enables you to load only the parts of a layer that you require, e.g., only roads with attribute type = highway.
• Enhanced Support for Feature Layer Styling
  • Additional styling options
  • Field expressions are supported enabling layers to be styled based on attribute field values.
  • "Extend to Ground" property supported now for both polylines and polygons (to create a partition such as a wall or fence).
  • Property sheet style settings allow TerraExplorer for Web users to modify base properties. Changes are saved between sessions.

Modify Terrain and Mesh

The powerful capabilities of the modify terrain have been extended to the 3D mesh layer, enabling the surface of the base terrain or a 3D mesh layer to be raised or lowered according to the elevation values of a modify mesh polygon's points. Among other things, this object allows users to integrate one 3D mesh layer inside a larger layer.

Hole on Terrain

TE4W expands its advanced objects’ support to include creation of hole on terrain objects. Cutting a hole on the terrain removes the terrain texture while maintaining the original contours of the terrain. The objects or feature layers created on the terrain in the area of the hole are drawn on the original contours of the terrain.  

Video on Terrain/Billboard

TE4W expands its advanced objects’ support to include creation of video on terrain objects. The Video on Terrain commands play a video file either on a selected area of the terrain (Video on Terrain), or on a floating billboard (Video Billboard).

Point Cloud Styling

TE4W expands its advanced objects’ support to include creation of video on terrain objects. The Video on Terrain commands play a video file either on a selected area of the terrain (Video on Terrain), or on a floating billboard (Video Billboard).

Shadow Analysis Improvements

• Improved shadow quality
• Set shadow color to blue for better analysis

New API

TE4W 7.3 offers expanded API capabilities, including:

• Set layer properties
• Get features from a layer
• Create base objects (points, lines and polygons)
• New callbacks, e.g., when an analysis object is added, tools are closed, and measurements finish

Cesium Support

• Cesium 3D library upgraded

Bug Fixes and Stability

This release improves overall stability and performance, including better support for accurate positioning in TE4W of mesh and point cloud layers whose positions were manually set in TerraExplorer Pro
