* Add symbol dds attributes and adapt style code generation
* Update to mapbox-gl-js/master
* Refactor SymbolFeature as a subclass of GeometryTileFeature
Prepares for enabling DDS on symbol paint properties by allowing the
SymbolFeatures, which we keep around after constructing SymbolLayout,
to be used in evaluating data-driven paint properties later in the
layout process.
* Draft approach for splitting icon/text paint properties
The `Program` types are set up to bind GL attributes to each of the
data-driven paint properties specified in the `PaintProperties` type
provided. Since `SymbolPaintProperties` specifies both `Text*` and
`Icon*` properties, the symbolIcon, symbolIconSDF, and symbolGlyph
programs each attempt to bind roughly double the number of attributes
that they actually need.
This change addresses this by:
- Adding the more specific `IconPaintProperties` and `TextPaintProperties` types, which are subsets of the full `SymbolPaintProperties`.
- The symbol layer continues to use its `SymbolPaintProperties paint` member to track layer property state, but it provides helpers that construct objects of each the specific `{Icon,Text}PaintProperties::Evaluated` type, for use by the painter.
- The three symbol programs instantiate `Program<>` using the appropriate `{Icon,Text}PaintProperties` type.
* check in generated style code
* Populate paint buffers for symbol DDS properties
* Address first round of review comments
* Refactor VectorTile{Layer,Feature} to explicitly share data
* Update submodule
Mapbox GL Native
A library for embedding interactive, customizable vector maps into native applications on multiple platforms. It takes stylesheets that conform to the Mapbox Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using OpenGL. Mapbox GL JS is the WebGL-based counterpart, designed for use on the Web.
The Mapbox GL ecosystem
This repository hosts the cross-platform Mapbox GL Native library, plus convenient SDKs for several platforms. The cross-platform library comes with a GLFW-based demo application for Ubuntu Linux and macOS. The SDKs target the usual languages on their respective platforms:
| SDK | Languages | Build status |
|---|---|---|
| Mapbox GL Native | C++14 |   |
| Mapbox Android SDK | Java |  |
| Mapbox iOS SDK | Objective-C or Swift |  |
| Mapbox macOS SDK | Objective-C, Swift, or AppleScript |  |
| node-mapbox-gl-native | Node.js |  |
| Mapbox Qt SDK | C++03 |  |
Additional Mapbox GL Native–based libraries for hybrid applications are developed outside of this repository:
| Toolkit | Android | iOS | Developer |
|---|---|---|---|
| React Native (npm) | ✅ | ✅ | |
| Apache Cordova (npm) | ✅ | ✅ | Telerik |
| NativeScript (npm) | ✅ | ✅ | Telerik |
| Xamarin | ✅ | ✅ | Xamarin |
If your platform or hybrid application framework isn’t listed here, consider embedding Mapbox GL JS using the standard Web capabilities on your platform.
