* Reorganize code for map items into separate folderVolker Hilsheimer2022-09-231-802/+0
| | | | | | | | | Splitting the code that only provides declarative wrappers around types from the implementations of the map and item rendering makes it easier to work with the code base and identify dependencies.

* More include cleanupVolker Hilsheimer2022-07-291-7/+10
| | | | | | | | | | | Remove includes of private headers from other modules where possible. Get rid of some duplicate includes, and try to group includes by module, with private includes in a separate block for better visibility where we have dependencies to private APIs.

* Use 'const' correctlyVolker Hilsheimer2022-07-281-5/+5
| | | | | | | | | | Don't return or pass const copies, use either plain copies or const references. Make getters const, make variables const, and use qAsConst in ranged for loops to avoid detaches.

* Add geometry simplification to MapPolyline/MapPolylineObjectQSGPaolo Angelelli2020-02-121-11/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces a metric-based implementation of the Ramer-Douglas-Peucker line simplification algorithm to generate a LOD pyramid for the polyline geometries. This comes with a related property (in MapItemBase), lodThreshold, that can be used to change the threshold after which no simplification will be used. By default the value of this property is 0, meaning that the behavior will be unchanged and no LOD will be used. This change also introduces LOD on map polyine objects QSG, for which no property is introduced, and there's a default threshold set to zoom level 12 (which appear to produce acceptable results). Finally, this patch makes use of a threadpool with 1 thread to enqueue geometry simplification tasks, which would otherwise freeze the UI when computing for the first time. Support for geometry simplification is currently added only to polylines. It might be of interest extending it to polygons as well, once a proper strategy for handling the simplification of inner holes has been identified. Finally, extending it to circles could be of interest, while potentially bringing only minor benefits, as circle geometries are currently fixed to 128 vertices. Also adds a MapObject-based delegate to the geojson viewer example.

* Enable mercator-to-screen projection in GLSLPaolo Angelelli2020-02-111-0/+823
With this change, all the geo-to-screen conversion, and the triangulation operations for geo polylines and geo polygon are performed either at set time or in the shader. A separate bounding box geometry is processed in the old way to provide a correct QtQuick Item geometry, that can be used for nesting mouse areas, performing translations, input event delivery, etc. With this approach, performance are improved by more than one order of magnitude in average, but complex geometries will of course benefit more. It also adds correct rendering support for polygons with holes, previously only rendered correctly by the MapboxGL plugin. The polyline shader has basic miter joins. The miter is skipped if the angle is too sharp to avoid complicating the implementation. This shader introduces some glitches when the polyline is minified, for which the real fix is to have LOD for the geometry, and render simplified geometries at low zoom levels (added in a subsequent patch). Note: this approach, at least in its current implementation, does not support enabling layers on individual items, only on the Map element.
