This fixes a bug where, for a zoom value greater than that of the highest zoom
stop, composite function interpolation would return nan. (Blocking a render
test over in #8593)
* Add failing tests for composite function edge case
The failing cases here are:
- Should interpolate before the first stop
- Should interpolate past the last stop
* Fix edge case in composite function interpolation
* Hold functions constant outside stop-defined domain
It should be safe to invoke GeometryTileWorker::setData multiple times without invoking GeometryTileWorker::setLayers. Therefore GeometryTileWorker::redoLayout() must not consume the layers.
This converts the style property classes (CirclePaintProperties and so on) to the same tuple-based approach as gl::Attribute and gl::Uniform. The approach is outlined in https://github.com/mapbox/cpp/blob/master/C%2B%2B%20Structural%20Metaprogramming.md.
The main advantage of this approach is it allows writing algorithms that work on sets of style properties, without resorting to code generation or manually repetitive code. This lets us iterate on approaches to data-driven properties more easily.
Another advantage is that the cascading, unevaluated, and evaluated states of a set of properties exist as independent structures, instead of individual properties holding their own state. This is a more functional approach that makes data flow clearer and reduces state.
Implemented observer callbacks so the style knows when the source’s attribution changes and the map knows when the style’s attribution changes. Also implemented a getter for a tile source’s attribution.
Fixes#2723.
Until Style::recalculate() is called to check that there are no visible layers using the source, we have to assume there are. Otherwise, Style::isLoaded() can return a false positive.
This paves the way for updates to filter and layout properties to trigger a source reload, without each SDK having to participate in the implementation.
* [core] geometry.hpp 0.8.0
* geojsonvt @ 6.0.0
* Update platform deps, build scripts
* Perf optimizations/cleanup
* Rebase in geometry@080
* D.R.Y. etc
* Ensure fill annotation geometries have closed rings.
* Optimizations
* Update to geojsonvt @ 6.1.0 for clean handoff between geojson parsing and geojsonvt
* Apply close multi/poly geoms for line annotations as well
* Layer source ID is immutable; must be provided to the constructor
* Layer source layer is mutable
* Layers with GeoJSON sources do not have a source layer
While here, make Layer::copy impl-private.
