New featureLuciadCPillar

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.

New featureLuciadCPillar

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.

New featureLuciadCPillar

LuciadCPillar now offers ambient occlusion and eye-dome lighting graphical effects on 3D maps. See GraphicsEffectsGraphicsEffectsGraphicsEffects, AmbientOcclusionEffectAmbientOcclusionEffectAmbientOcclusionEffect and EyeDomeLightingEffectEyeDomeLightingEffectEyeDomeLightingEffect for details. When enabled, they are applied on all the data on the map.

New featureLuciadCPillar

The GdalModelDecoderGdalModelDecoderGdalModelDecoder now supports decoding of 8 bit indexed color GeoTIFF data.

New featureLuciadCPillar

It is now possible to provide custom raster data and visualize it on the map. This can be accomplished using the new MultilevelTiledRasterModelBuilderMultilevelTiledRasterModelBuilderMultilevelTiledRasterModelBuilder and QuadTreeRasterModelBuilderQuadTreeRasterModelBuilderQuadTreeRasterModelBuilder classes. This for example allows you to implement your own raster format, or position a single image on the map. The article introduction to raster models provides more information on these classes.

You can indicate that your custom raster data may change. To enable this you need to call MultilevelTiledRasterModelBuilder::enableInvalidationMultilevelTiledRasterModelBuilder::enableInvalidationMultilevelTiledRasterModelBuilder::enableInvalidation or QuadTreeRasterModelBuilder::enableInvalidationQuadTreeRasterModelBuilder::enableInvalidationQuadTreeRasterModelBuilder::enableInvalidation. This results in the creation of an IRasterModelIRasterModelIRasterModel which returns true for the method IRasterModel::canInvalidateIRasterModel::canInvalidateIRasterModel::canInvalidate and on which you can call IRasterModel::invalidateIRasterModel::invalidateIRasterModel::invalidate. Invalidating the raster instructs LuciadCPillar to reload the data from the model and update the view accordingly.

GeometryFactoryGeometryFactoryGeometryFactory now also has a createPoint method that takes a CoordinateCoordinateCoordinate as input.

LCP-19, LCP-21, LCP-22, LCP-25, LCP-65, LCP-290, LCP-290, LCP-343
Vector loading performance has been improved for larger vector data sets.
  • 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.

Ogc3DTilesModelDecoder::decodeOgc3DTilesModelDecoder::decodeOgc3DTilesModelDecoder::decode has been overloaded so that you can now configure Ogc3DTilesModelDecoder::OptionsOgc3DTilesModelDecoder::OptionsOgc3DTilesModelDecoder::Options for the decoding of OGC 3D tiles data. These options allow you to configure a custom IDataLoaderIDataLoaderIDataLoader to fetch the OGC 3D Tiles resources, in case the default data loading from a server or the file system is not adequate for your use case. HspcModelDecoder::decodeHspcModelDecoder::decodeHspcModelDecoder::decode also supports this.
