* Remove MapObjects from labsVolker Hilsheimer2022-09-261-77/+0
| | | | | | | | | | | | | | | The feature was designed to enable map backends to implement their own rendering of the map, and map items. It was never really used by any of the backends we supported, and introduced a lot of complexity to the code base. The idea as such has perhaps merit, but for now we focus on the basic functionality of Qt Location. Support for Qt Location when the Qt Quick scene graph is not used is not a part of that.

* Enable mercator-to-screen projection in GLSLPaolo Angelelli2020-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix QGeoMapObject handling in reference implementationPaolo Angelelli2018-04-221-3/+5
| | | | | | | | | | | | | | | | | setVisible was neither changing the visibility nor triggering repaint. Pimpls weren't removing themselves in their destructors when dynamically added/removed via QGeoMapObjectView add/removeMapObject. This patch also factors out the duplicated QGeoMapObject support from QGeoTiledMapLabs and QGeoMapObjectsOverlay and moves it into an own class, QGeoMapObjectQSGSupport. To properly flush the scene graph nodes upon object removal, a pointer to the QSGNode is added to the MapObject struct, now moved inside QGeoMapObjectQSGSupport.

* Introduce map objects reference implementationPaolo Angelelli2018-04-171-0/+61
This patch introduces a reference implementation for the QGeoMapObject subclasses in the locationlabs module. If this module is built, all current plugins, with the exception of mapboxgl, will also be able to render map objects. The current reference implementation of map objects is not optimized, but it can be useful for both testing and feature parity (so that switching between plugins will give the same result).
