Since label rendering isn't clipped, having a parent tile, and only a handful of child tiles loaded may result in some labels being rendered twice (from the parent tile, and the up to three child tiles that necessitate the parent tile remaining in the list). This patch makes sure that in one location, it only ever renders one set of labels, by favoring the parent tile until all required child tiles have been loaded.
The depth range is now set slightly differently. Both ends of the range
are shifted for each layer to solve some precision issues.
Some layers draw multiple things at different depths. For example, fill
layers draw fills and antialiasing separately. To handle this case, I
added setDepthSublayer(n) which a
Use a macro to completely remove all instantiations of mbgl::gl::debugging::group so that we aren't executing the code to generate the arguments to the object instantiation
Before C++11, std::list's implementation of size was O(n). It should be
all O(1) now, but it is probably still a good idea to use empty() to
emphasize the intend.
Following the same steps from #1548 and #1912 for GLFW and iOS ports.
Also removed a redundant check if transform state is changing since
we're already dealing with that.
Relevant changes:
- Added 'defaultFadeDuration' and 'defaultTransitionDelay' to MapData;
- Painter & StyleParser now receives a reference to MapData;
- As previously seen on the code: 300ms is the default fade duration
and 0ms is the default transition duration;
- We no longer pass the current time point to Style, since it now uses
MapData.animationTime, which gets updated in MapContext::update().
- Updated StyleParser check to use a mock MapData;
This eliminates a reference loop: VectorTileData holds StyleLayers which
hold StyleBuckets which held Sources which hold VectorTileDatas. This
breaks the StyleBucket -> Source link in favor of manually resolving the
reference where necessary.
Also add a virtual setState() method to give subclasses a chance
to intercept the change of state. This will be used by VectorTileData
to release resources when the TileData becomes immutable.
This moves all texture updates and buffer uploads to the beginning of every frame, before we issue any drawing commands. This means the GPU typically has much more time to upload the data in the background until we actually need it, and doesn't have to pause to store/load the framebuffer.
