ProjectedCollisionBox encapsulates geometry of the projected
collision box, it is using union and thus provides memory save
- 12 bytes per collision box instance.
RenderTile and Tile will be split when ochestration movces to a separate thread.
This PR improves encapsulation of Tiles management: now performed within TilePyramid.
`RenderSymbolLayer` does not have to update dynamic vertices of its buckets, this logic is moved to placement (which is already updates opacity vertices).
* fixes clustering of labels when text variable placement enabled - as assignes `usesVariablePlacement` per bucket
* simplifies the code in `RenderSymbolLayer` (the `RenderSymbolLayer::upload()` is now omitted).
* symbol buckets are not modified after orchestration finishes
Symbols are placed accordingly to their viewport Y order,
if the style `symbol-z-order` is set to `viewport-y`.
This improves rendering of symbol layers, where icons are allowed
to overlap but not text.
[node] Hook up map-wide "crossSourceCollisions" option, defaulting to true.
[test] Pass "crossSourceCollisions" test option through test harness; enable cross-source-collisions tests on native.
- Fixes issue #12461.
- Only implement "avoid edges" in MapMode::Tile since it's no longer relevant in Static or Continuous mode.
- New: Force "avoid edges" to "true" for line labels, since in tile mode they'll always clip poorly at tile boundaries.
- Remove unused "withinPlus0/inside" logic.
Since placements will be committed even if they do not need the full
fade duration to fade features in, we need the new `fadeStartTime` to
keep track of how long we still need to fade. This is important because
if we fade too long we will trigger another placement and never stop
rendering.
Native version of mapbox/mapbox-gl-js#6548.
Port of mapbox/mapbox-gl-js#6550.
Prevents symbols that share the same layout properties from colliding against each other.
Bump GL JS pin to get regression test.
Rename "bucketName" -> "bucketLeaderID" to make it clearer what it represents.
- assert symbol layer tiles must be geometry tiles, instead of dynamically checking
- re-use retainedBucketQuery iterator instead of calling find twice.
- Symbol querying is now global instead of per-tile
- Symbols that bleed over tile boundaries no longer missed in queries
- Symbol results now sorted based on rendering order (ie overlapping symbols change their sort order when a bearing change causes their render order to change)
- Placement::retainedQueryData now responsible for maintaining symbol querying data for buckets that may no longer be in the TilePyramid.
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.
