* [core] fix opacity of duplicate labels with -allow-overlap: trueAnsis Brammanis2018-02-151-3/+8
|
* Prune unused layers from CrossTileSymbolIndexChris Loer2018-01-192-0/+13
| | | | Fixes issue #10939 -- removed layers would leak entries in the CrossTileSymbolIndex.
* [core] Prevent symbols at the same zoom from sharing a crossTileID.Chris Loer2018-01-172-9/+35
| | | | | Port of GL JS PR #5994. Fixes issue #10844, which would allow multiple symbols in a tile to share the same crossTileID as one of their duplicate parent-tile symbols. Once the symbols shared a crossTileID, they would permanently remain "duplicates" of each other, even after increasing zoom level allowed the CrossTileSymbolIndex to distinguish between them.

* [ios,macos] Darwin implementation of a CoreText-based LocalGlyphRasterizer.Chris Loer2017-12-112-2/+6
| | | | | - Changing font weight does not currently appear to be working. - Glyph metric extraction code not working; currently unused.
* [core] Enable local glyph generation using TinySDF.Chris Loer2017-12-113-5/+66
| | | | | | | - Platform-specific LocalGlyphRasterizer is responsible for deciding which glyphs to rasterize locally and for implementing the rasterization. - Default platform implementation doesn't locally generate any glyphs -> no behavior change - Unit test uses StubLocalGlyphRasterizer, which returns a single fixed bitmap for all CJK glyphs - Rename glyph_loader.test to glyph_manager.test

* [core] Symbol cross-fading.Chris Loer2017-11-172-4/+18
| | | | Hold onto tiles after they've been removed from the render tree long enough to run a fade animation on their symbols.

* [core] Skip fade animation for placed symbols that are currently offscreen.Chris Loer2017-11-174-40/+82
| | | | | Don't mark items that are outside the collision grid range as placed. Requires new ignore because GL JS issue #5654 allows insertion of symbols outside the CollisionIndex range, and those symbols can cascade in to affect items within the viewport.
* [core] Split MapMode::Still into Static and TileAnsis Brammanis2017-11-171-3/+6
| | | | | `Tile` makes sure the symbols in the resulting tile are tileable while symbols in `Still` match rendering in `Continuous` mode.

* [core] Remove dead codeChris Loer2017-11-173-371/+0
| | | | | | - CollisionTile - FrameHistory - PlacementConfig
* [core] Use floats instead of ints for Shaping.Chris Loer2017-11-172-5/+5
| | | | Brings gl-native shaping closer to gl-js.
* [core] Switch from background to foreground placementChris Loer2017-11-173-76/+48
| | | | | | | | | | | | - Background placement code now just generates static symbol buffers - Don't render GeometryTiles until their symbols are loaded. This is necessary for the CrossTileSymbolIndex to successfully prevent flicker. - SymbolInstances are transferred to SymbolBucket for use on foreground during collision detection - Symbols are sorted on foreground by sorting their index buffer but leaving vertex buffers intact (only works within one segment) - Vertical glyphs are generated at same time as horizontal glyphs. `reprojectLineLabels` chooses which one to use at render time and hides the other. - Icons are now always represented with a single collision box, even if they're placed along a line (this means their rotation alignment may be wrong, but the approach of representing them with multiple collision boxes wasn't very accurate either). - Generate vertices for new debug collision boxes and collision circles - Only add symbols within tile boundaries (reduces work, avoids double-draw) - Update symbol_projection.cpp to support line label projection calls from CollisionIndex.
* [core] Add global CollisionIndex to replace CollisionTile.Chris Loer2017-11-172-0/+399
| | | | | | | - Switches from tile to viewport coordinates - Represents line labels with circle geometries - Projects line labels at collision detection time to improve accuracy - Adapts tile-based symbol queries to viewport coordinates
* [core] Add Placement class.Chris Loer2017-11-172-0/+389
| | | | Responsible for running global collision detection/symbol placement algorithm and updating symbol opacity buffers accordingly.
* [core] Add CrossTileSymbolIndex.Chris Loer2017-11-172-0/+234
| | | | This class is responsible for tracking which symbols are "the same" between tiles at different zoom levels, so that symbol opacities (fade animations) can be copied smoothly between tiles.

* [core] improve legibility of labels that follow linesAnsis Brammanis2017-07-113-297/+55
| | | | | | | | | | port https://github.com/mapbox/mapbox-gl-js/pull/4781 This improves legibility of labels that follow lines in pitched views. The previous approach used the limited information in the shader to calculate put the glyph in approximatelyright place. The new approach does this more accurately by doing it on the cpu where we have access to the entire line geometry.
