  • v1.57 Changes

    May 01, 2019
    ➕ Additions :tada:
    • 👌 Improved 3D Tiles streaming performance, resulting in ~67% camera tour load time reduction, ~44% camera tour load count reduction. And for general camera movement, ~20% load time reduction with ~27% tile load count reduction. Tile load priority changed to focus on loading tiles in the center of the screen first. Added the following tileset optimizations, which unless stated otherwise are enabled by default. #7774
      • Added Cesium3DTileset.cullRequestsWhileMoving option to ignore requests for tiles that will likely be out-of-view due to the camera's movement when they come back from the server.
      • Added Cesium3DTileset.cullRequestsWhileMovingMultiplier option to act as a multiplier when used in culling requests while moving. Larger is more aggressive culling, smaller less aggressive culling.
      • Added Cesium3DTileset.preloadFlightDestinations option to preload tiles at the camera's flight destination while the camera is in flight.
      • Added Cesium3DTileset.preferLeaves option to prefer loading of leaves. Good for additive refinement point clouds. Set to false by default.
      • Added Cesium3DTileset.progressiveResolutionHeightFraction option to load tiles at a smaller resolution first. This can help get a quick layer of tiles down while full resolution tiles continue to load.
      • Added Cesium3DTileset.foveatedScreenSpaceError option to prioritize loading tiles in the center of the screen.
      • Added Cesium3DTileset.foveatedConeSize option to control the cone size that determines which tiles are deferred for loading. Tiles outside the cone are potentially deferred.
      • Added Cesium3DTileset.foveatedMinimumScreenSpaceErrorRelaxation option to control the starting screen space error relaxation for tiles outside the foveated cone.
      • Added Cesium3DTileset.foveatedInterpolationCallback option to control how screen space error threshold is interpolated for tiles outside the foveated cone.
      • Added Cesium3DTileset.foveatedTimeDelay option to control how long in seconds to wait after the camera stops moving before deferred tiles start loading in.
    • ➕ Added new parameter to PolylineGlowMaterial called taperPower, that works similar to the existing glowPower parameter, to taper the back of the line away. #7626
    • ➕ Added Cesium3DTileset.preloadWhenHidden tileset option to preload tiles when tileset.show is false. Loads tiles as if the tileset is visible but does not render them. #7774
    • Added support for the KHR_texture_transform glTF extension. #7549
    • ➕ Added functions to remove samples from SampledProperty and SampledPositionProperty. #7723
    • ➕ Added support for color-to-alpha with a threshold on imagery layers. #7727
    • ➕ Add CZML processing for heightReference and extrudedHeightReference for geoemtry types that support it.
    • 📚 CesiumMath.toSNorm documentation changed to reflect the function's implementation. #7774
    • ➕ Added CesiumMath.normalize to convert a scalar value in an arbitrary range to a scalar in the range [0.0, 1.0]. #7774
    🛠 Fixes :wrench:
    • 🛠 Fixed an error when loading the same glTF model in two separate viewers. #7688
    • 🛠 Fixed an error where clampToHeightMostDetailed or sampleHeightMostDetailed would crash if entities were created when the promise resolved. #7690
    • 🛠 Fixed an issue with compositing merged entity availability. #7717
    • 🛠 Fixed an error where many imagery layers within a single tile would cause parts of the tile to render as black on some platforms. #7649
    • 🛠 Fixed a bug that could cause terrain with a single, global root tile (e.g. that uses WebMercatorTilingScheme) to be culled unexpectedly in some views. #7702
    • 🛠 Fixed a problem where instanced 3D models were incorrectly lit when using physically based materials. #7775
    • 🛠 Fixed a bug where glTF models with certain blend modes were rendered incorrectly in browsers that support ImageBitmap. #7795

  • v1.56.1 Changes

    April 02, 2019
    ➕ Additions :tada:
    • 🚚 Resource.fetchImage now takes a preferImageBitmap option to use createImageBitmap when supported to move image decode off the main thread. This option defaults to false.
    💥 Breaking Changes :mega:
    • The following breaking changes are relative to 1.56. The Resource.fetchImage behavior is now identical to 1.55 and earlier.
      • Changed Resource.fetchImage back to return an Image by default, instead of an ImageBitmap when supported. Note that an ImageBitmap cannot be flipped during texture upload. Instead, set flipY : true during fetch to flip it.
      • Changed the default flipY option in Resource.fetchImage to false. This only has an effect when ImageBitmap is used.

  • v1.56 Changes

    April 01, 2019
    💥 Breaking Changes :mega:
    • 👍 Resource.fetchImage now returns an ImageBitmap instead of Image when supported. This allows for decoding images while fetching using createImageBitmap to greatly speed up texture upload and decrease frame drops when loading models with large textures. #7579
    • 💅 Cesium3DTileStyle.style now has an empty Object as its default value, instead of undefined. #7567
    • Scene.clampToHeight now takes an optional width argument before the result argument. #7693
    • 🚚 In the Resource class, addQueryParameters and addTemplateValues have been removed. Please use setQueryParameters and setTemplateValues instead. #7695
    Deprecated :hourglass_flowing_sand:
    • Resource.fetchImage now takes an options object. Use resource.fetchImage({ preferBlob: true }) instead of resource.fetchImage(true). The previous function definition will no longer work in 1.57. #7579
    ➕ Additions :tada:
    • ➕ Added support for touch and hold gesture. The touch and hold delay can be customized by updating ScreenSpaceEventHandler.touchHoldDelayMilliseconds. #7286
    • 💻 Resource.fetchImage now has a flipY option to vertically flip an image during fetch & decode. It is only valid when ImageBitmapOptions is supported by the browser. #7579
    • ➕ Added backFaceCulling and normalShading options to PointCloudShading. Both options are only applicable for point clouds containing normals. #7399
    • 💅 Cesium3DTileStyle.style reacts to updates and represents the current state of the style. #7567
    🛠 Fixes :wrench:
    • Fixed the value for BlendFunction.ONE_MINUS_CONSTANT_COLOR. #7624
    • 🛠 Fixed HeadingPitchRoll.pitch being NaN when using .fromQuaternion due to a rounding error for pitches close to +/- 90°. #7654
    • 🛠 Fixed a type of crash caused by the camera being rotated through terrain. #6783
    • 🛠 Fixed an error in Resource when used with template replacements using numeric keys. #7668
    • 🛠 Fixed an error in Cesium3DTilePointFeature where anchorLineColor used the same color instance instead of cloning the color #7686

  • v1.55 Changes

    March 01, 2019
    💥 Breaking Changes :mega:
    • czm_materialInput.slope is now an angle in radians between 0 and pi/2 (flat to vertical), rather than a projected length 1 to 0 (flat to vertical).

    • ⚡️ Updated terrain and imagery rendering, resulting in terrain/imagery loading ~33% faster and using ~33% less data #7061
    • czm_materialInput.aspect was added as an angle in radians between 0 and 2pi (east, north, west to south).
    • ➕ Added CZML arcType support for polyline and polygon, which supersedes followSurface. followSurface is still supported for compatibility with existing documents. #7582
    🛠 Fixes :wrench:
    • 🛠 Fixed an issue where models would cause a crash on load if some primitives were Draco encoded and others were not. #7383
    • 🛠 Fixed an issue where RTL labels not reversing correctly non alphabetic characters #7501
    • 🛠 Fixed Node.js support for the Resource class and any functionality using it internally.
    • 🛠 Fixed an issue where some ground polygons crossing the Prime Meridian would have incorrect bounding rectangles. #7533
    • 🛠 Fixed an issue where polygons on terrain using rhumb lines where being rendered incorrectly. #7538
    • 🛠 Fixed an issue with EllipsoidRhumbLines.findIntersectionWithLongitude when longitude was IDL. #7551
    • 🛠 Fixed model silhouette colors when rendering with high dynamic range. #7563
    • 🛠 Fixed an issue with ground polylines on globes that use ellipsoids other than WGS84. #7552
