  • v1.99 Changes

    November 01, 2022
    Major Announcements :loudspeaker:
    • 📦 Starting with version 1.100, CesiumJS will be published alongside two smaller packages @cesium/engine and @cesium/widgets #10824:
      • The source code will been paritioned into two folders: packages/engine and packages/widgets.
      • These workspaces packages will follow semantic versioning.
      • These workspaces packages will be published as ES modules with TypeScript definitions.
      • The combined CesiumJS release will continue to be published, however, the Source folder will only contain the following:
      • Cesium.js
      • Cesium.d.ts
      • Assets
      • ThirdParty
      • Widgets(CSS files only)
      • The ability to import modules and TypeScript definitions from individual files will been removed. Any imports should originate from the cesium module (import { Cartesian3 } from "cesium";) or the combined Cesium.js file (import { Cartesian3 } from "Source/Cesium.js";);
    ➕ Additions :tada:
    • ➕ Added support for I3S 3D Object and IntegratedMesh Layers. #9634
    Deprecated :hourglass_flowing_sand:
    • 🚚 The viewer parameter in KmlTour.prototype.play was deprecated in Cesium 1.99. It will be removed in 1.100. Instead of a Viewer, pass a CesiumWidget instead. #10845
    🛠 Fixes :wrench:
    • 🛠 Fixed a bug where the scale of a Model was being incorrectly applied to its bounding sphere. #10855
    • 🛠 Fixed a bug where rendering a Model with image-based lighting while specular environment maps were unsupported caused a crash. #10859
    • 🛠 Fixed a bug where request render mode was broken when a ground primitive is added. #10756

  • v1.98.1 Changes

    October 03, 2022
    • 🚀 This is an npm only release to fix the improperly published 1.98.

  • v1.98 Changes

    October 03, 2022
    💥 Breaking Changes :mega:
    • 🚀 As of the previous release (1.97), new Model() is an internal constructor and must not be used directly. Use Model.fromGltf() instead. #10778
    ➕ Additions :tada:
    • Added support for the WEB3D_quantized_attributes extension found in some glTF 1.0 models. #10758
    🛠 Fixes :wrench:
    • 🛠 Fixed a bug where instanced models without normals would not render. #10765
    • 🛠 Fixed a regression where i3dm with scale and without rotation would render incorrectly. #10808
    • 🛠 Fixed a regression where instanced feature IDs were not processed correctly #10771
    • 🛠 Fixed a regression where Cesium3DTileFeature.setProperty() was not creating properties for unknown property IDs. #10775
    • Fixed a regression where pnts tiles with 3DTILES_draco_point_compression and <= 8 quantization bits were being rendered incorrectly. #10794
    • 🛠 Fixed a regression where glTF models with unused nodes would crash #10813
    • 🛠 Fixed a regression where tilesets would not load in multiple Viewers. #10828
    • 🛠 Fixed a bug where camera would not follow the Viewer.trackedEntity if it had a model with a HeightReference other than NONE. #10805
    • 🛠 Fixed a bug where calling removeAll on a ClippingPlaneCollection attached to a Model would cause a crash. #10827
    • 🛠 Fixed a bug where replacing a Model's ClippingPlaneCollection with one of the same length would cause a crash. #10831
    • 🛠 Fixed a bug where KMLs with a NetworkLink with viewRefreshMode=='onRegion' would cause Cesium to make numerous resource requests and possibly trigger an out of memory error. #10790
    • 🛠 Fixed a bug where calling Vector3DTileContent.getFeature before a render update could result in no feature being returned. #10819

  • v1.97 Changes

    September 01, 2022
    Major Announcements :loudspeaker:
    • CesiumJS has switched to a new architecture for loading glTF models and tilesets to enable:
    • Usage notes for the new glTF architecture:
      • Those using ModelExperimental.fromGltf() should now use Model.fromGltf().
      • The enableModelExperimental flag was removed, as tilesets and entities always use the new architecture.
      • The new implementation of Model uses the same public API as before, so no other changes are necessary.
    💥 Breaking Changes :mega:
    • 🍱 glTF 1.0 assets are no longer fully supported. glTF 1.0 techniques are converted to PBR materials where possible, but more complex techniques will no longer function correctly. If custom GLSL shaders are needed, use CustomShader instead. #10648
    • The glTF 2.0 extension KHR_techniques_webgl and KHR_materials_common are also no longer fully supported. Materials are converted to PBR materials where possible.
    • 👌 Support for rendering instanced models on the CPU has been removed.
    • 🚚 Model.gltf, Model.basePath, Model.pendingTextureLoads (properties), and Model.dequantizeInShader (constructor option) have been removed.
    • 🚚 ModelMesh and ModelMaterial have been removed.
    • new Model() is an internal constructor and must not be used directly. Use Model.fromGltf() instead. #10778
    ➕ Additions :tada:
    • 🍱 Model can now classify other assets with a given classificationType. #10623
    • 👍 Model now supports back face culling for point clouds. #10703
    • 🔧 Export asset files such as CSS in package.json, allowing bundlers to import without additional configuration. #9212
    • 📦 The sideEffects field in package.json is now specified, allowing more conservative bundlers like Webpack to enable tree shaking by default. #10714
    • 👍 Model entities now support CustomShader. #10747
    🛠 Fixes :wrench:
    • Fixed bug with Viewer.flyTo where camera could go underground when target is an Entity with ModelGraphics with HeightReference.CLAMP_TO_GROUND or HeightReference.RELATIVE_TO_GROUND. #10631
    • 🛠 Fixed issues running CesiumJS under Node.js when using ES modules. #10684
    • 🛠 Fixed the incorrect lighting of instanced models. #10690
    • 🛠 Fixed developer error with Camera.flyTo with an orientation and a Rectangle value for destination. #10704
    • 🛠 Fixed rendering bug with points in .vctr format, where points wouldn't show until picked or styled. #10707
    • Fixed bounding volume calculations for glTF models with KHR_mesh_quantization and normalized positions. #10741
