  • v1.50 Changes

    October 01, 2018
    💥 Breaking Changes :mega:
    • Clipping planes on tilesets now use the root tile's transform, or the root tile's bounding sphere if a transform is not defined. #7034
      • This is to make clipping planes' coordinates always relative to the object they're attached to. So if you were positioning the clipping planes as in the example below, this is no longer necessary: javascript clippingPlanes.modelMatrix = Cesium.Transforms.eastNorthUpToFixedFrame(tileset.boundingSphere.center);
      • This also fixes several issues with clipping planes not using the correct transform for tilesets with children.
    ➕ Additions :tada:
    • 🎉 Initial support for clamping to 3D Tiles. #6934
      • Added Scene.sampleHeight to get the height of geometry in the scene. May be used to clamp objects to the globe, 3D Tiles, or primitives in the scene.
      • Added Scene.clampToHeight to clamp a cartesian position to the scene geometry.
      • Requires depth texture support (WEBGL_depth_texture or WEBKIT_WEBGL_depth_texture). Added Scene.sampleHeightSupported and Scene.clampToHeightSupported functions for checking if height sampling is supported.
    • ➕ Added Cesium3DTileset.initialTilesLoaded to indicate that all tiles in the initial view are loaded. #6934
    • Added support for glTF extension KHR_materials_pbrSpecularGlossiness #7006.
    • Added support for glTF extension KHR_materials_unlit #6977.
    • Added support for glTF extensions KHR_techniques_webgl and KHR_blend. #6805
    • ⚡️ Update gltf-pipeline to 2.0. #6805
    • ➕ Added cartographicLimitRectangle to Globe. Use this to limit terrain and imagery to a specific Rectangle area. #6987
    • ➕ Added OpenCageGeocoderService, which provides geocoding via OpenCage. #7015
    • ➕ Added ground atmosphere lighting in 3D. This can be toggled with Globe.showGroundAtmosphere. 6877
      • Added Globe.nightFadeOutDistance and Globe.nightFadeInDistance to configure when ground atmosphere night lighting fades in and out. 6877
    • ➕ Added onStop event to Clock that fires each time stopTime is reached. #7066
    🛠 Fixes :wrench:
    • 🛠 Fixed picking for overlapping translucent primitives. #7039
    • 🛠 Fixed an issue in the 3D Tiles traversal where tilesets would render with mixed level of detail if an external tileset was visible but its root tile was not. #7099
    • 🛠 Fixed an issue in the 3D Tiles traversal where external tilesets would not always traverse to their root tile. #7035
    • 🛠 Fixed an issue in the 3D Tiles traversal where empty tiles would be selected instead of their nearest loaded ancestors. #7011
    • 🛠 Fixed an issue where scaling near zero with an model animation could cause rendering to stop. #6954
    • 🛠 Fixed bug where credits weren't displaying correctly if more than one viewer was initialized [#6965](expect(https://github.com/AnalyticalGraphicsInc/cesium/issues/6965)
    • 🛠 Fixed entity show issues. #7048

    💥 Breaking Changes :mega:
    • ✂ Removed ClippingPlaneCollection.clone. #6872
    • 🔄 Changed Globe.pick to return a position in ECEF coordinates regardless of the current scene mode.

  • v1.47 Changes

    July 02, 2018
    Highlights :sparkler:
    • ➕ Added support for polylines on terrain #6689 #6615
    • ➕ Added heightReference and extrudedHeightReference properties to CorridorGraphics, EllipseGraphics, PolygonGraphics and RectangleGraphics. #6717
    • PostProcessStage has a selected property which is an array of primitives used for selectively applying a post-process stage. #6476
    💥 Breaking Changes :mega:
    • glTF 2.0 models corrected to face +Z forwards per specification. Internally Cesium uses +X as forward, so a new +Z to +X rotation was added for 2.0 models only. To fix models that are oriented incorrectly after this change:
      • If the model faces +X forwards update the glTF to face +Z forwards. This can be done by loading the glTF in a model editor and applying a 90 degree clockwise rotation about the up-axis. Alternatively, add a new root node to the glTF node hierarchy whose matrix is [0,0,1,0,0,1,0,0,-1,0,0,0,0,0,0,1].
      • Apply a -90 degree rotation to the model's heading. This can be done by setting the model's orientation using the Entity API or from within CZML. See #6738 for more details.
    • ⚡️ Dropped support for directory URLs when loading tilesets to match the updated 3D Tiles spec. #6502
    • KML and GeoJSON now use PolylineGraphics instead of CorridorGraphics for polylines on terrain. #6706
    ➕ Additions :tada:
    • ➕ Added support for polylines on terrain #6689 #6615
      • Use the clampToGround option for PolylineGraphics (polyline entities).
      • Requires depth texture support (WEBGL_depth_texture or WEBKIT_WEBGL_depth_texture), otherwise clampToGround will be ignored. Use Entity.supportsPolylinesOnTerrain to check for support.
      • Added GroundPolylinePrimitive and GroundPolylineGeometry.
    • PostProcessStage has a selected property which is an array of primitives used for selectively applying a post-process stage. #6476
      • The PostProcessStageLibrary.createBlackAndWhiteStage and PostProcessStageLibrary.createSilhouetteStage have per-feature support.
    • ➕ Added CZML support for zIndex with corridor, ellipse, polygon, polyline and rectangle. #6708
    • ➕ Added CZML clampToGround option for polyline. #6706
    • ➕ Added support for RTC_CENTER property in batched 3D model tilesets to conform to the updated 3D Tiles spec. #6488
    • ➕ Added heightReference and extrudedHeightReference properties to CorridorGraphics, EllipseGraphics, PolygonGraphics and RectangleGraphics. #6717
      • This can be used in conjunction with the height and/or extrudedHeight properties to clamp the geometry to terrain or set the height relative to terrain.
      • Note, this will not make the geometry conform to terrain. Extruded geoemtry that is clamped to the ground will have a flat top will sinks into the terrain at the base.
    🛠 Fixes :wrench:
    • 🛠 Fixed a bug that caused Cesium to be unable to load local resources in Electron. #6726
    • 🛠 Fixed a bug causing crashes with custom vertex attributes on Geometry crossing the IDL. Attributes will be barycentrically interpolated. #6644
    • 🛠 Fixed a bug causing Point Cloud tiles with unsigned int batch-ids to not load. #6666
    • 🛠 Fixed a bug with Draco encoded i3dm tiles, and loading two Draco models with the same url. #6668
    • 🛠 Fixed a bug caused by creating a polygon with positions at the same longitude/latitude position but different heights #6731
    • 🛠 Fixed terrain clipping when the camera was close to flat terrain and was using logarithmic depth. #6701
    • 🛠 Fixed KML bug that constantly requested the same image if it failed to load. #6710
    • 👌 Improved billboard and label rendering so they no longer sink into terrain when clamped to ground. #6621
    • 🛠 Fixed an issue where KMLs containing a colorMode of random could return the exact same color on successive calls to Color.fromRandom().
    • 📜 Iso8601.MAXIMUM_VALUE now formats to a string which can be parsed by fromIso8601.
    • 🛠 Fixed material support when using an image that is already loaded #6729

  • v1.46.1 Changes

    June 01, 2018
    • 🚀 This is an npm only release to fix the improperly published 1.46.0. There were no code changes.

  • v1.46 Changes

    June 01, 2018
    Highlights :sparkler:
    • ➕ Added support for materials on terrain entities (entities with unspecified height) and GroundPrimitives. #6393
    • ➕ Added a post-processing framework. #5615
    • ➕ Added zIndex for ground geometry, including corridor, ellipse, polygon and rectangle entities. #6362
    💥 Breaking Changes :mega:
    • ParticleSystem no longer uses forces. #6510
    • Particle no longer uses size, rate, lifeTime, life, minimumLife, maximumLife, minimumWidth, minimumHeight, maximumWidth, and maximumHeight. #6510
    • ✂ Removed Scene.copyGlobeDepth. Globe depth will now be copied by default when supported. #6393
    • 0️⃣ The default classificationType for GroundPrimitive, CorridorGraphics, EllipseGraphics, PolygonGraphics and RectangleGraphics is now ClassificationType.TERRAIN. If you wish the geometry to color both terrain and 3D tiles, pass in the option classificationType: Cesium.ClassificationType.BOTH.
    • ✂ Removed support for the options argument for Credit #6373. Pass in an html string instead.
    • glTF 2.0 models corrected to face +Z forwards per specification. Internally Cesium uses +X as forward, so a new +Z to +X rotation was added for 2.0 models only. #6632
    Deprecated :hourglass_flowing_sand:
    • 🚚 The Scene.fxaa property has been deprecated and will be removed in Cesium 1.47. Use Scene.postProcessStages.fxaa.enabled.
    ➕ Additions :tada:
    • ➕ Added support for materials on terrain entities (entities with unspecified height) and GroundPrimitives. #6393
      • Only available for ClassificationType.TERRAIN at this time. Adding a material to a terrain Entity will cause it to behave as if it is ClassificationType.TERRAIN.
      • Requires depth texture support (WEBGL_depth_texture or WEBKIT_WEBGL_depth_texture), so materials on terrain entities and GroundPrimitives are not supported in Internet Explorer.
      • Best suited for notational patterns and not intended for precisely mapping textures to terrain - for that use case, use SingleTileImageryProvider.
    • ➕ Added GroundPrimitive.supportsMaterials and Entity.supportsMaterialsforEntitiesOnTerrain, both of which can be used to check if materials on terrain entities and GroundPrimitives is supported. #6393
    • ➕ Added a post-processing framework. #5615
      • Added Scene.postProcessStages which is a collection of post-process stages to be run in order.
        • Has a built-in ambientOcclusion property which will apply screen space ambient occlusion to the scene and run before all stages.
        • Has a built-in bloom property which applies a bloom filter to the scene before all other stages but after the ambient occlusion stage.
        • Has a built-in fxaa property which applies Fast Approximate Anti-aliasing (FXAA) to the scene after all other stages.
      • Added PostProcessStageLibrary which contains several built-in stages that can be added to the collection.
      • Added PostProcessStageComposite for multi-stage post-processes like depth of field.
      • Added a new Sandcastle label Post Processing to showcase the different built-in post-process stages.
      • Added zIndex for ground geometry, including corridor, ellipse, polygon and rectangle entities. #6362
      • Added Rectangle.equalsEpsilon for comparing the equality of two rectangles #6533
    🛠 Fixes :wrench:
    • 🛠 Fixed a bug causing custom TilingScheme classes to not be able to use a GeographicProjection. #6524
    • 🛠 Fixed incorrect 3D Tiles statistics when a tile fails during processing. #6558
    • 🛠 Fixed race condition causing intermittent crash when changing geometry show value #3061
    • ProviderViewModels with no category are displayed in an untitled group in BaseLayerPicker instead of being labeled as 'Other' #6574
    • 🛠 Fixed a bug causing intermittent crashes with clipping planes due to uninitialized textures. #6576
    • ➕ Added a workaround for clipping planes causing a picking shader compilation failure for gltf models and 3D Tilesets in Internet Explorer #6575

    • Cesium no longer ships with a demo Bing Maps API key.
    • 0️⃣ BingMapsImageryProvider is no longer the default base imagery layer. (Bing imagery itself is still the default, however it is provided through Cesium ion)
    • 0️⃣ BingMapsGeocoderService is no longer the default geocoding service.
    • 0️⃣ If you wish to continue to use your own Bing API key for imagery and geocoding, you can go back to the old default behavior by constructing the Viewer as follows: javascript Cesium.BingMapsApi.defaultKey = 'yourBingKey'; var viewer = new Cesium.Viewer('cesiumContainer', { imageryProvider : new Cesium.BingMapsImageryProvider({ url : 'https://dev.virtualearth.net' }), geocoder : [ new Cesium.CartographicGeocoderService(), new Cesium.BingMapsGeocoderService() ] });
    Deprecated :hourglass_flowing_sand:

ParticleSystem.minimumWidth and ParticleSystem.minimumHeight will now be ParticleSystem.minimumImageSize, ParticleSystem.maximumWidth and ParticleSystem.maximumHeight will now be ParticleSystem.maximumImageSize, and ParticleSystem.width and ParticleSystem.height will now be ParticleSystem.imageSize. Use of the minimumWidth, minimumHeight, maximumWidth, maximumHeight, width, and height parameters is deprecated and will be removed in Cesium 1.46.
    ➕ Additions :tada:
    • ➕ Added option logarithmicDepthBuffer to Scene. With this option there is typically a single frustum using logarithmic depth rendered. This increases performance by issuing less draw calls to the GPU and helps to avoid artifacts on the connection of two frustums. #5851

    April 02, 2018
    Highlights :sparkler:
    • ➕ Added a new Sandcastle label, New in X.X which will include all new Sandcastle demos added for the current release. #6384
    • Added support for glTF models with Draco geometry compression. #5120
    • ➕ Added support for ordering in DataSourceCollection. #6316
    💥 Breaking Changes :mega:
    • GeometryVisualizer now requires primitive and groundPrimitive parameters. #6316
    • 🚚 For all classes/functions that take a Resource instance, all additional parameters that are part of the Resource class have been removed. This generally includes proxy, headers and query parameters. #6368
    • 🚚 All low level load functions including loadArrayBuffer, loadBlob, loadImage, loadJson, loadJsonp, loadText, loadXML and loadWithXhr have been removed. Please use the equivalent fetch functions on the Resource class. #6368
    Deprecated :hourglass_flowing_sand:
    • 🚚 ClippingPlaneCollection is now supported in Internet Explorer, so ClippingPlaneCollection.isSupported has been deprecated and will be removed in Cesium 1.45.
    • 🚚 ClippingPlaneCollection should now be used with ClippingPlane objects instead of Plane. Use of Plane objects has been deprecated and will be removed in Cesium 1.45.
    • 🚚 Credit now takes an html and showOnScreen parameters instead of an options object. Use of the options parameter is deprecated and will be removed in Cesium 1.46.
    • 🚚 Credit.text, Credit.imageUrl and Credit.link properties have all been deprecated and will be removed in Cesium 1.46. Use Credit.html to retrieve the credit content.
