Change Log

v1.10.1 - 2024-06-03

This release updates cesium-native from v0.35.0 to v0.36.0. See the changelog for a complete list of changes in cesium-native.

v1.10.0 - 2024-05-01

Additions 🎉
  • Added support for Cesium ion servers in single user mode. Tokens are not required to stream assets from such servers.
Fixes 🔧
  • Fixed a bug where CesiumCreditSystem would delete itself from its scene when other additive scenes were unloaded.

In addition to the above, this release updates cesium-native from v0.34.0 to v0.35.0. See the changelog for a complete list of changes in cesium-native.

v1.9.0 - 2024-04-01

Additions 🎉
  • Added CesiumWebMapTileServiceRasterOverlay, which enables Web Map Tile Service (WMTS) imagery to be draped on a Cesium3DTileset.
  • Added support for the KHR_texture_transform glTF extension - including rotation - for picking with CesiumFeatureIdTexture.
Fixes 🔧
  • Normal, metallic-roughness, and occlusion textures from glTF models will now be correctly treated as linear rather than sRGB.
  • Fixed a bug where UVs were not properly interpolated in CesiumFeatureIdTexture.GetFeatureIdFromHit, resulting in incorrect values.

In addition to the above, this release updates cesium-native from v0.33.0 to v0.34.0. See the changelog for a complete list of changes in cesium-native.

v1.8.0 - 2024-03-01

Breaking Changes 📣
  • Feature IDs and metadata are now parsed through the EXT_mesh_features and EXT_structural_metadata extensions respectively. Models with EXT_feature_metadata will still be parsed, but their metadata will no longer be accessible.
  • CesiumDefaultTilesetMaterial and CesiumUnlitTilesetMaterial have had their overlay-related parameters renamed. For instance, _overlay0TextureCoordinateIndex has now become _overlayTextureCoordinateIndex_0. Custom materials that relied on the previous naming scheme may break.
Additions 🎉
  • Added CesiumCartographicPolygon and CesiumPolygonRasterOverlay, which together can be used to clip out polygonal areas of a Cesium3DTileset. These new classes are only available in Unity 2022.2+ because they require Unity's Splines package.
  • Added CesiumFeatureIdSet, which represents a feature ID set in EXT_mesh_features.
  • Added CesiumFeatureIdAttribute and CesiumFeatureIdTexture, which derive from CesiumFeatureIdSet and respectively represent a feature ID attribute and feature ID texture in EXT_mesh_features.
  • Added CesiumPrimitiveFeatures, a component that provides access to the EXT_mesh_features on a glTF primitive when it is loaded by Cesium3DTileset.
  • Added CesiumPropertyTableProperty, which represents a property table property in EXT_structural_metadata and can be used to retrieve metadata.
  • Added CesiumPropertyTable, which represents a property table in EXT_structural_metadata.
  • Added CesiumModelMetadata, a component that provides access to the EXT_structural_metadata on a glTF model when it is loaded by Cesium3DTileset.
  • Added CesiumMetadataValue, which can hold a metadata value from EXT_structural_metadata while abstracting away its type.
  • Added a distance property to CesiumOriginShift, which specifies the maximum allowed distance from the current origin before it is shifted.
  • Added support for the KHR_texture_transform glTF extension - including rotation - in baseColorTexture, metallicRoughnessTexture, emissiveTexture, normalTexture, and occlusionTexture. The transformation is now applied on the GPU via nodes in the Material, rather than on the CPU by directly modifying texture coordinates.
  • Added materialKey to CesiumRasterOverlay, which matches the overlay to its corresponding parameters in the tileset's material. This allows for explicit ordering of raster overlays and overlay-specific effects.
  • CesiumCameraController can now accept custom input actions that override the default inputs.
Fixes 🔧
  • Removed the "Universal Additional Camera Data" script from DynamicCamera, as it shows up as a missing script in other render pipelines.
  • Fixed a bug where adding a CesiumSubScene as the child of an existing CesiumGeoreference in editor would cause the parent CesiumGeoreference to have its coordinates reset to the default.
  • Fixed the "DynamicCamera is not nested inside a game object with a CesiumGeoreference" warning when adding a new DynamicCamera in the editor.
  • Fixed support for loading textures with less than four channels.
  • Fixed "Destroying assets is not permitted to avoid data loss" error when using a custom opaque material with texture assets on a Cesium3DTileset.
  • Fixed jump at the end of the flight path in CesiumFlyToController.
Deprecated ⏳
  • CesiumMetadata has been deprecated. Instead, retrieve the CesiumModelMetadata component attached to a tile game object in order to access its glTF metadata.
  • CesiumFeature has been deprecated. Instead, retrieve feature IDs from the CesiumPrimitiveFeatures component attached to a primitive game object in order to access its glTF features. Feature IDs can be used to retrieve metadata from the CesiumModelMetadata attached to its parent.
  • flyToGranularityDegrees in CesiumFlyToController has been deprecated. CesiumFlyToController no longer works using keypoints, so this value is unnecessary.

In addition to the above, this release updates cesium-native from v0.27.4 to v0.33.0. See the changelog for a complete list of changes in cesium-native.

v1.7.1 - 2023-12-14

v1.6.0

Additions 🎉
  • Added support for Universal Windows Platform (UWP), which is required to build applications for the Holo Lens 2.
  • Added ComputeLoadProgress function to estimate the percentage of the 3D tileset that has been loaded for the current view.
Fixes 🔧
  • Fixed a bug that prevented building on iOS.
  • Fixed a bug where KTX tilesets did not display properly on iOS devices due to a missing check for ETC1 texture format.

v1.4.0 - 2023-07-03

Additions 🎉
  • Added OnTileGameObjectCreated event to Cesium3DTileset class, which allows customizing the Tile GameObjects as they are loaded.
  • KTX2 compressed textures now remain compressed all the way to the GPU, reducing GPU memory usage.
Fixes 🔧
  • Fixed how the occlusion strength is used in the default tileset shader which was causing shadows to be too dark.
  • Fixed a bug that caused a prefab with a CesiumGlobeAnchor to lose its position after save/reload.
  • Fixed a MissingReferenceException when entering Play mode with "Domain Reload" disabled. This would also prevent tilesets with raster overlays from appearing at all in Play mode.

In addition to the above, this release updates cesium-native from v0.25.0 to v0.25.1. See the changelog for a complete list of changes in cesium-native.

v1.3.1 - 2023-06-06

Fixes 🔧
  • Fixed a bug that prevented building on iOS.

v1.3.0 - 2023-06-01

Additions 🎉
  • Cesium components now appear under the "Cesium" category in the Component menu. Previously were under "Scripts > Cesium for Unity"
  • Cesium components now display the Cesium logo as their icon, rather than the default Unity script icon.
Fixes 🔧
  • Fixed a bug where Cesium3DTileset would not reflect changes made to the properties of its opaque material in the Editor.
  • Fixed a bug that could cause missing textures when using two raster overlays with the same projection on a single tileset.
  • Fixed a bug where changing the origin on a CesiumGeoreference would not propogate these changes to the active CesiumSubScene, if one exists.
  • Reduced the amount of extraneous camera rotation in the CesiumCameraController after a frame hitch by using Time.smoothDeltaTime.
  • Fixed a bug that caused mipmaps to be generated for textures that shouldn't be mipmapped, sometimes leading to cracks between tiles and other problems.

In addition to the above, this release updates cesium-native from v0.24.0 to v0.25.0. See the changelog for a complete list of changes in cesium-native.

v1.2.0 - 2023-05-09

Additions 🎉
  • Added a scale property to CesiumGeoreference. This allows the entire globe to be scaled up or down with better precision than the scale property on the georeference's Transform.
Fixes 🔧
  • Fixed a bug that caused tiles to be displaced when changing the transform of a CesiumGeoreference at runtime.
  • Fixed a bug that caused primitive numbers to be negative in the names of tile game objects when the tile mesh had multiple primitives.

v1.1.0 - 2023-05-01

Breaking Changes 📣
  • CesiumObjectPool is no longer accessible from outside the CesiumRuntime assembly.
Additions 🎉
  • Added support for primitives with the TRIANGLE_STRIP and TRIANGLE_FAN topology types.
  • Missing normals are now generated as "flat" normals by default, as required by the glTF specification. An option on Cesium3DTileset allows the user to request smooth normals instead, which will improve performance for most meshes by reducing geometry duplication.
  • Moved mipmap generation from the main thread to a worker thread.
Fixes 🔧
  • Added dependencies on the ShaderGraph and InputSystem packages to resolve material / script compilation errors.
  • Fixed another bug where CesiumCameraController tried to access a non-existent input in the legacy input system.
  • Removed an extra "delimiter" added to the end of on-screen credits in some cases.
  • Fixed a memory leak of Mesh objects when entering and exiting Play mode in the Unity Editor.
  • Fixed a crash that happened when attempting to create physics meshes for degenerate triangle meshes.

In addition to the above, this release updates cesium-native from v0.23.0 to v0.24.0. See the changelog for a complete list of changes in cesium-native.

v1.0.0 - 2023-04-03

Additions 🎉
  • Added support for Unity's built-in render pipeline.
  • Added CesiumPointCloudShading, which allows point cloud tilesets to be rendered with attenuation based on geometric error. Attenuation is currently only supported in the Universal Render Pipeline (URP).
  • GameObject instances created for the tiles in a Cesium3DTileset now inherit the layer of the parent tileset.
  • Added the CesiumTileExcluder abstract class. By creating a class derived from CesiumTileExcluder, then adding it to a Cesium3DTileset's game object, you can implement custom rules for excluding tiles in the Cesium3DTileset from loading and rendering.
  • Added setting in CesiumRuntimeSettings to configure the maximum number of responses to keep in the request cache.
  • Added setting in CesiumRuntimeSettings to configure the number of reads from the cache database before each prune.
Fixes 🔧
  • Fixed a bug that prevented the use of pre-existing mipmaps, such as those loaded from KTX2.
  • Fixed a bug where CesiumCameraController tried to access non-existent inputs in the legacy input system.
  • Fixed a bug that could cause a crash when using the search box with a dataset already selected in the Cesium ion Assets window.
  • Fixed a bug that prevented sorting the contents of the Cesium ion Assets window in descending order.

In addition to the above, this release updates cesium-native from v0.22.1 to v0.23.0. See the changelog for a complete list of changes in cesium-native.

v0.3.1

Fixes 🔧
  • Fixed a bug introduced in v0.3.0 that caused an exception when attempting load Cesium3DTilesets from a local file.

In addition to the above, this release updates cesium-native from v0.22.0 to v0.22.1. See the changelog for a complete list of changes in cesium-native.

v0.3.0

Breaking Changes 📣
  • Removed the positionAuthority, unityX, unityY, and unityZ properties from CesiumGlobeAnchor. Also removed the SetPositionUnity method.
  • Removed the CesiumGlobeAnchorPositionAuthority enum. The authoritative position is now always found in the positionGlobeFixed property. The object's Unity world position can be obtained from its Transform.
  • Marked the longitude, latitude, and height properties on CesiumGlobeAnchor as obsolete. Use the longitudeLatitudeHeight property instead.
  • Marked the ecefX, ecefY, and ecefZ properties on CesiumGlobeAnchor as obsolete. Use the positionGlobeFixed property instead.
  • Marked SetPositionLongitudeLatitudeHeight and SetPositionEarthCenteredEarthFixed methods on CesiumGlobeAnchor as obsolete. Set the longitudeLatitudeHeight or positionGlobeFixed property instead.
  • Replaced MetadataProperty with CesiumFeature. Metadata features are now separated based on feature tables where properties are accessed by name.
  • Replaced CesiumMetadata.GetProperties with CesiumMetadata.GetFeatures, which returns an array of CesiumFeatures.
Additions 🎉
  • Added support for rendering point clouds (pnts).
  • CesiumGlobeAnchor now stores a precise, globe-relative orientation and scale in addition to position.
  • Added localToGlobeFixedMatrix, longitudeLatitudeHeight, positionGlobeFixed, rotationGlobeFixed, rotationEastUpNorth, scaleGlobeFixed, and scaleEastUpNorth properties to CesiumGlobeAnchor.
  • Added the Restart method to CesiumGlobeAnchor, which can be use to reinitialize the component from its serialized values.
  • Moved the Cesium tileset shaders from the Shader Graphs shader category to the new Cesium shader category.
  • Added CesiumDebugColorizeTilesRasterOverlay to visualize how a tileset is divided into tiles.
Fixes 🔧
  • Fixed a bug that prevented caching of 3D Tiles and overlay requests.
  • Fixed a bug that could cause the Cesium ion Token Troubleshooting panel to crash the Unity Editor.
  • Added a workaround for a crash in the Burst Compiler (bcl.exe) in Unity 2022.2 when using il2cpp.
  • Fixed a bug that could cause incorrect metadata to be associated with a feature, especially in Draco-encoded tiles.

In addition to the above, this release updates cesium-native from v0.21.3 to v0.22.0. See the changelog for a complete list of changes in cesium-native.

v0.2.0

Breaking Changes 📣
  • Renamed CesiumTransforms to CesiumWgs84Ellipsoid.
Additions 🎉
  • Added CesiumCameraController, a globe-aware controller that adapts its speed and clipping planes based on its height from the globe.
  • Added CesiumFlyToController, a controller that can smoothly fly to locations across the globe.
  • Added an option to add a DynamicCamera from the Cesium panel to the scene. The DynamicCamera contains CesiumCameraController and CesiumFlyToController components and offers easy navigation of the globe.
  • Added support for building to iOS.
  • Added support for building to Android x86-64 devices like the Magic Leap 2.
Fixes 🔧
  • Fixed a bug where CesiumGeoreference, CesiumGlobeAnchor, and CesiumSubScene would not properly update when their values were changed by undos or pasted values.
  • CesiumRuntimeSettings is now stored in Assets/CesiumSettings/Resources instead of Assets/Settings/Resources.
  • Added an explicit Physics.SyncTransforms when CesiumOriginShift activates or deactivates sub-scenes, avoiding a brief period of potentially very incorrect collisions.

In addition to the above, this release updates cesium-native from v0.21.1 to v0.21.3. See the changelog for a complete list of changes in cesium-native.

v0.1.2

Fixes 🔧
  • Fixed a bug that caused Cesium for Unity to fail to compile in Unity 2022.2 and potentially in other scenarios.
  • Fixed a bug that led to an exception when the project name included characters outside the printable ASCII range.

v0.1.1

Fixes 🔧
  • Fixed a bug that caused raster overlay tiles to be missing or mixed up, especially when zooming in close and then back out.

v0.1.0

The initial release of Cesium for Unity!
