LuciadRIA Release notes

You can now limit the total number of points used by all point cloud layers on a map with the new RIAMap.performanceHints.maxPointCount property. LuciadRIA distributes this point budget automatically and continuously across the point cloud layers visible on the map. See Tuning performance and visual quality of point clouds.

LuciadRIA can now decode and visualize Gaussian splats. Gaussian splatting is a novel scene-representation and 3D rendering technique that uses a large amount of tiny 3D Gaussian primitives ("splats") to create photorealistic views of real-world scenes.

LuciadRIA can consume Gaussian splats as OGC 3D Tiles with glTF payloads that make use of the KHR_gaussian_splatting or KHR_gaussian_splatting_compression_spz_2 extension of the glTF specification.

You can visualize a Gaussian splatting dataset by constructing a TileSet3DLayer with an OGC3DTilesModel. Also see TileSet3DLayer.gaussianSplatsStyle, which allows you to customize the styling of the Gaussian splats, using expressions for example, and to tweak other performance-related settings.

LuciadRIA depends on the libraries tinyply and spz for parsing ply and spz files respectively.

See Visualize Gaussian splats for more information.

We have added full support for the military standard 'APP-6 NATO Joint Military Symbology, Edition E Version 2, October 2025'.

The symbols of the Cyberspace symbol set, which we added previous release have been upgraded from APP-6E E Version 1 to APP-6E Version 2.

You can visualize the APP-6E symbols using the Military Symbology samples, located in samples/symbology within the release directory.

APP-6E - Fictional Scenario.

• Decoding NVG XML content
• Decoding NVG XML streaming content, of both full sync and partial updates
• Visualization of NVG Features
• Editing of NVG Features, of both shapes and properties
• Creation of NVG Features
• Encoding of NVG XML content

OrientedBox.getCorners() and OrientedBox.getCornerPoints() now return a fixed-size tuple of eight corners, typed as OrientedBoxCorners<Vector3> and OrientedBoxCorners<Point>, instead of an Vector3[] and a Point[]. An oriented box always has exactly eight corners, so callers can now destructure or index all of them without checking for undefined.

Existing code keeps working: a tuple is still an array, so it can be iterated, mapped and passed wherever an array of corners was expected.

Undoable.undo() and Undoable.redo() can now be asynchronous. An undoable often updates a model, and such an update can take a request to a server, for example on a WFS-T store. Returning a promise is optional: an Undoable that applies its change synchronously returns nothing, as before. Existing Undoable implementations keep working unchanged.

As a result, UndoManager.undo() and UndoManager.redo() now return Promise<void> instead of void. If every Undoable in your UndoManager is synchronous, that promise never rejects, and you can keep calling both methods and ignore what they return. As soon as one of them can be asynchronous, await it inside a try/catch block, so that you find out whether the operation was applied and can report a failed model update to your user.

See the Adding undo/redo support to your application guide for details.

RIAMap.maxMemoryUsageHint (property and constructor option) has been deprecated in favor of RIAMap.performanceHints.maxMemoryUsage.

It is now possible to configure the APP-6A and APP-6B "Antitank Ditch" symbols to be painted using the "Under Construction" stroke pattern. To paint these symbols using the "Under Construction" stroke pattern, set the typeOfEquipment modifier to "U" or "Under Construction".

• Guarded Unit
• Controlling Headquarters
• Purpose
• Special Headquarters
• SIGINT Mobility Indicator
• Target Designator
• Target Number Extension
• Unlisted Point Information

It is now possible to configure the APP-6A and APP-6B "Biological and Chemical Attack, Release Event" symbols to be painted using the "Chemical" icon. To paint these symbols using the "Chemical" icon, set the typeOfEquipment modifier to "C" or "Chemical".

Fixed incorrect rendering of a number of APP-6A and APP-6B icons.

APP-6A:

• Hostile or Insurgent Infantry (2.X.3.1.15): now uses the Infantry icon, where it used to have the Motorised Infantry icon.

APP-6A and APP-6B:

• Hail (3.X.7.3): now uses the correct icon.
• Ice Pellets (3.X.7.4): now use the correct color.
• Ice Crystals (3.X.7.5): now use the correct color.
• Freezing Fog (3.X.9.2.1): now use the correct color.

APP-6B:

• Multi-Functional Earth Mover (1.X.3.2.2.3.2.1): now has a circular frame instead of a rectangular one when in the Friendly affiliation.

The APP-6E Cyberspace symbols now display the headquarters staff, feint/dummy and task force indicators when their hqTaskForceDummy modifier is set. Previously these indicators were missing.

In addition, the hqTaskForceDummy modifier now only offers the indicators that the APP-6E standard allows for the following symbol sets:

• Land Equipment (15): the headquarters and task force indicators are disabled.
• Land Installation (20): the task force indicator is disabled.
• Dismounted Individual (27): the headquarters and task force indicators are disabled.
• Activities (40): the feint/dummy and task force indicators are disabled.
• Cyberspace - Non Unit (64): the feint/dummy indicator is now enabled. Previously none of the indicators were available for this symbol set.

The APP-6E mined area symbols now display the feint/dummy indicator when their hqTaskForceDummy modifier is set to one of the Feint/Dummy values. Previously the indicator was missing, so a decoy area was indistinguishable from a real one.

The change affects the following APP-6E symbols:

• Minefield - Dynamic Depiction
• Mined Area
• Mined Area, Fenced

WFSQueryOptions.filter now only accepts an OGCCondition, such as the id filter returned by identifiers(). Passing property() or literal() to WFSFeatureStore.query(), spatialQuery() or queryWithLock() now results in a compile-time error.

OGCCondition, a predicate that evaluates to true or false, and OGCExpression, which evaluates to a value such as a string or number, are now distinct types. The FilterFactory functions type their arguments and results accordingly, so passing an expression where a condition is expected, or the other way around, is now a compile-time error. For example, and(property("a"), ...) no longer compiles. These calls already failed at runtime.

func() returns OGCCondition & OGCExpression, so you can use a function both as a condition and as an operand. OGCFilterEncoder.encode() now only accepts an OGCCondition.

Store is now an abstract class instead of an interface, and its spatialQuery, get, add, put and remove operations are no longer optional: Store and FeatureModel always declare them, so checks such as typeof store.add === "function" no longer work. Use the new isOperationSupported(operation) method instead to find out which operations can actually be called; calling an unsupported one throws a ProgrammingError. query is always supported.

Adapt a custom store by extending Store and implementing query. Override the operations the store supports (spatialQuery, get, add, put and remove) and report them from isOperationSupported.

Store now provides the event system itself: it always has an on method and a store reports its changes with the new emitStoreChangedEvent method. on only accepts "StoreChanged", and its callback receives "add", "update" or "remove" instead of any string. Another event throws a ProgrammingError. Due to these changes, a custom store has to extend Store instead of implementing it, and a store that overrides on must narrow its callback.

Several map effect properties were renamed or re-expressed. The old names are deprecated but keep working (they are mapped onto the new ones), so existing code keeps rendering the same result.

The FogEffect now expresses fog in metric units instead of the previous unitless values:

• density is deprecated in favor of visibility: the distance in meters at which the fog fully obscures the scene near the ground. Note that visibility works inversely to density, a higher visibility means thinner fog.
• heightFalloff is deprecated in favor of halvingHeight: the altitude in meters over which the fog thins by half. Uniform fog, previously heightFalloff: 0, is now expressed as halvingHeight: null.

If you are unsure which values to use, start from the defaults (a visibility of 80000 m and a halvingHeight of 4000 m) and adjust from there. See the fog effect documentation for more guidance on choosing metric values.

Other effect properties were renamed only, without a change in meaning:

• DepthOfFieldEffect: scale becomes blurStrength, focalDepth becomes focusDistance, focusRange becomes blurStartDistance, and noFocusRange becomes fullBlurDistance.
• LightScatteringAtmosphere: affectsTerrain becomes aerialPerspective.

LightScatteringAtmosphere also gained a new mieAnisotropy property, controlling how tightly the Mie haze clusters around the sun.

Touch and mouse input on labels no longer prevents the map from panning, zooming, or picking. The HTML label layer is now transparent to input by default, so a click or touch on label text falls through to the map. Previously, a finger resting on a label blocked the map from receiving touch events.

Interactive label content keeps working: native elements (<a href>, <button>, <input>, <select>, <textarea>, <label> and contenteditable elements) receive input automatically. To make custom content interactive, add the lcd-label-interactive CSS class to it. If you previously attached a handler to the whole label element rather than to an inner control, add that class to the element that should be clickable. See How to add interactive content to labels.

The hostile text modifier now accepts only two values: ENY (the default) and null.

You can use the modifier to disable the ENY indicator: setting it to null removes the annotation from both the icon label and the stroke decoration of tactical graphics. Previously, symbols with a hostile affiliation were always annotated with ENY, regardless of the modifier value.

The change affects all supported military symbology standards.

A number of control measure Line symbols in APP-6D and MIL-STD 2525D no longer display the generic PL ("phase line") label. Previously these symbols were labeled twice: once with PL followed by the first uniqueDesignation modifier, and once with the abbreviation specific to the symbol followed by the second uniqueDesignation modifier. They are now labeled only with their own abbreviation, followed by the first uniqueDesignation modifier.

The change affects the following symbols. All of them belong to symbol set 25 (Control Measure); the symbol code is given for each symbol.
