LuciadCPillar Release notes

The BezierCurveBezierCurveBezierCurve geometry now also supports cubic interpolation. A Bézier curve can now be created by on of these methods:

• GeometryFactory::createQuadraticBezierCurveGeometryFactory::createQuadraticBezierCurveGeometryFactory::createQuadraticBezierCurve: creates quadratic Bézier curve that is defined by 3 control points.
• GeometryFactory::createCubicBezierCurveGeometryFactory::createCubicBezierCurveGeometryFactory::createCubicBezierCurve: creates a cubic Bézier curve that is defined by 4 control points.

You can make the distinction between both using the new BezierCurve::getControlPointCountBezierCurve::getControlPointCountBezierCurve::getControlPointCount function. Also, the editing sample demonstrates how to create and edit a CubicBezierCurve.

• FeatureCanvas::LabelDrawCommandFeatureCanvas::LabelDrawCommandFeatureCanvas::LabelDrawCommand
• FeatureCanvas::TextDrawCommandFeatureCanvas::TextDrawCommandFeatureCanvas::TextDrawCommand
• FeatureCanvas::IconDrawCommandFeatureCanvas::IconDrawCommandFeatureCanvas::IconDrawCommand

• FeatureLayerLoadingStrategy::LoadSpatiallyFeatureLayerLoadingStrategy::LoadSpatiallyFeatureLayerLoadingStrategy::LoadSpatially is used.
• The feature uses a geocentric or topocentric reference.

• The GeometryFactory::createBezierCurve function was renamed to GeometryFactory::createQuadraticBezierCurveGeometryFactory::createQuadraticBezierCurveGeometryFactory::createQuadraticBezierCurve.
• The BezierCurve::getControlPointBezierCurve::getControlPointBezierCurve::getControlPoint method now takes an index as parameter. To revert to the previous behavior, you can now call this method with an index of 1.
• The ObservableBezierCurveUtil::deriveControlPointObservableBezierCurveUtil::deriveControlPointObservableBezierCurveUtil::deriveControlPoint now also takes an index as parameter to align with the BezierCurve::getControlPointBezierCurve::getControlPointBezierCurve::getControlPoint method.

• System.Text.Json was updated to version 8.0.5
• NLog was updated to version 5.3.4

Added support for editing PolygonPolygonPolygon instances using the EditorEditorEditor class. This is done using the new PolygonHandlesProviderPolygonHandlesProviderPolygonHandlesProvider class. Editing polygons works out of the box: this new handles provider is used by default by FeatureHandlesProviderFeatureHandlesProviderFeatureHandlesProvider and CompositeGeometryHandlesProviderCompositeGeometryHandlesProviderCompositeGeometryHandlesProvider.

In addition to this functionality, a few utilities where added to modify and handle PolygonPolygonPolygon instances:

• ObservablePolygonUtilObservablePolygonUtilObservablePolygonUtil
• Polygon::replaceExteriorRingPolygon::replaceExteriorRingPolygon::replaceExteriorRing
• Polygon::replaceInteriorRingPolygon::replaceInteriorRingPolygon::replaceInteriorRing
• Polygon::appendInteriorRingPolygon::appendInteriorRingPolygon::appendInteriorRing
• Polygon::removeInteriorRingPolygon::removeInteriorRingPolygon::removeInteriorRing

A couple of methods now use double values instead of integer values:

• Map::resizeMap::resizeMap::resize
• Map::getWidthMap::getWidthMap::getWidth and Map::getHeightMap::getHeightMap::getHeight
• Camera::getWidthCamera::getWidthCamera::getWidth and Camera::getHeightCamera::getHeightCamera::getHeight

This was done to avoid precision loss due to rounding errors. In rare cases, this precision loss could lead to incorrect behavior like:

• map-wide jittering effects
• a (small) black border at the side of the map
• the map content being stretched out very slightly

It is now possible to specify an OcclusionModeOcclusionModeOcclusionMode when painting geometries and (non-label) icons or text. This allows you to (partially) show 3D objects that would otherwise be obscured by other 3D objects. See

• FeatureCanvas::GeometryDrawCommand::occlusionModeFeatureCanvas::GeometryDrawCommand::occlusionModeFeatureCanvas::GeometryDrawCommand::occlusionMode
• FeatureCanvas::IconDrawCommand::occlusionModeFeatureCanvas::IconDrawCommand::occlusionModeFeatureCanvas::IconDrawCommand::occlusionMode
• FeatureCanvas::TextDrawCommand::occlusionModeFeatureCanvas::TextDrawCommand::occlusionModeFeatureCanvas::TextDrawCommand::occlusionMode

The precision of WKT and EPSG references that use an ellipsoidal version of the Lambert azimuthal equal area projection has been improved. This affects the following EPSG codes:

• 3035
• 3571 to 3576
• 5633, 5635, 5636, 5638
• 6931, 6932
• 9039
• 9947

The C# WinForms and WPF integration code has been improved to more easily support scenarios where a Map is removed from the application window, and moved to a different component in that same application window. An example of such a scenario is when the WinForms or WPF Map components are used within a docking UI framework.

Before this improvement, this would either cause crashes or the map component would not paint its Map content anymore.

It is now possible to create 3D icons from glTF files in LuciadCPillar by using the FeatureCanvas::drawIcon3DFeatureCanvas::drawIcon3DFeatureCanvas::drawIcon3D method. FeatureCanvas::Icon3DDrawCommandFeatureCanvas::Icon3DDrawCommandFeatureCanvas::Icon3DDrawCommand allows you to set the glTF source file to load as well as other properties such as transformations: scale, rotation, orientation and translation. As well as color modulation, mesh position, query-ability of the mesh and a setting to tell if the mesh contains transparent surfaces.

The camera sample demonstrates how to import a glTF file. This information can also be found in the article Learn how to load and visualize your glTF data.
For information about the limitation of our glTF support in LuciadCPillar please refer to the article Which glTF version is supported and what are the limitations?.

LuciadCPillar has been upgraded to support .NET standard 2.0. It is now much easier to use the LuciadCPillar C# binary on newer .NET implementations. LuciadCPillar already supported .NET Framework 4.7.2 (or later). It now also supports all .NET Core and .NET versions (5 or later).

Note that building and running the LuciadCPillar C# samples still requires .NET Framework 4.7.2.

• The presence of a MapScaleMapScaleMapScale with a small denominator in the layer's IFeaturePainterIFeaturePainterIFeaturePainter implementation or in the layer's FeatureQueryConfigurationFeatureQueryConfigurationFeatureQueryConfiguration
• The presence of a large feature in the layer's IFeatureModelIFeatureModelIFeatureModel
• A model update of this large feature in the layer's IFeatureModelIFeatureModelIFeatureModel
• A camera position that is looking towards the horizon (in 3D), or the additional presence of many small features (>50000) in the layer's IFeatureModelIFeatureModelIFeatureModel, concentrated in a small area.

It is now possible to replace the IFeaturePainterIFeaturePainterIFeaturePainter of a FeatureLayerFeatureLayerFeatureLayer by a new feature painter instance. This allows you to change the styling for all features in the layer.

Note: There is currently the limitation that the detail levels of the new IFeaturePainterIFeaturePainterIFeaturePainter must be the same as those of the previous feature painter.

• The Map can now correctly visualize non-world covering elevation data sets correctly. In previous versions it clips away all other data outside the extents of the elevation data set. This is not the case anymore: all data outside the elevation data's extent is now painted at elevation 0.
• The map can now visualize multiple elevation data sets at the same time. In previous versions only the top-most elevation layer is used to generate terrain. Now all layers that contain elevation data are used to generate terrain.

LuciadCPillar for Android allows you to develop GPU accelerated geospatial situational awareness applications targeted to run on Android mobile devices. LuciadCPillar for Android is an SDK that supports both Kotlin and Java development. It is feature equivalent with LuciadCPillar for desktop.

To get started, consult the product documentation and select the Android profile at the top right of the page. The product documentation includes installation guides, a Java API reference and a set of ready-to-run kotlin samples that can be installed on your mobile device from Android studio.

You can now enable GPU texture compression on TileSet3DLayerTileSet3DLayerTileSet3DLayer for OGC 3D Tiles mesh data. This can greatly reduce the amount of GPU memory needed, improve performance and stability.

Enable when displaying meshes with large textures, such as reality capture reconstructions. By default, texture compression is enabled.
Disable when displaying meshes with lookup textures, such as CAD models.

If your environment does not support GPU texture compression, setting the flag has no effect.

• Data starts appearing on the screen up to 10 times faster right after adding a vector layer or after zooming in to a different detail level.
• Data loading throughput is up to 2 times larger.
• Data appears and disappears up to 5-10 times faster while navigating.
• The map's frame rate is higher while vector data is loaded. Navigation now remains smooth at all times during loading.

The CPillar map now supports high DPI rendering. This means that fonts, icons and other map elements are automatically resized in proportion to the display scale configured in the operating system. This also means that map scale calculations use the configured DPI to get a correct interpretation.

When integrating the CPillar map in a UI framework the DPI and the display scale must be configured on the Map::RendererMap::RendererMap::Renderer. You can read more on this in the article on support for high DPI displays. The article on integration within Qt provides details on how this is done for the Qt UI toolkit.

The API allows to provide icons for multiple resolutions such that the CPillar map can use the best applicable for your screen setup. For this purpose, the IIconIIconIIcon class was modified to allow painting an icon in different resolutions.
