CesiumJS 1.123

1.123 - 2024-11-01

Highlights include:

• Updated default 3D Tiles and Model lighting when using PBR in order to create a more realistic appearance #12129
• Exposed Fog.visualDensityScalar to allow modifying the visual density of fog without affecting the culling aspects. Alongside this, the density calculation was adjusted to make it more smooth across heights. #12248
• Added ScreenSpaceCameraController.maximumTiltAngle to limit how much the camera can tilt. #12169

CesiumJS 1.122

1.122 - 2024-10-01

Highlights include:

• Added CallbackPositionProperty to allow lazy entity position evaluation. #12170
• Added enableVerticalExaggeration option to models. Set this value to false to prevent model exaggeration when Scene.verticalExaggeration is set to a value other than 1.0. #12141
• Fix Texture errors when using a HTMLVideoElement. #12219
• Fixed noise in ambient occlusion post process. #12201

See the changelog for the complete list of changes.

CesiumJS 1.121

1.121 - 2024-09-03

Highlights include:

• Enable MSAA by default with 4 samples. This smooths jagged edges for increased visual realism. #12158
• Switched the default (non-HDR) tonemapping for models, atmosphere, and globe from ACES to PBR Neutral Tonemap from Khronos. The widens the gamut of possible colors, and provides more consistent color appearances across renderers. #12160
• Expose the tonemapper and exposure properties of PostProcessStageCollection to allow changing the tonemap used when HDR is turned on. This defaults to the PBR Neutral Tonemap from Khronos #12160
• Added WaterMask globe material, which visualizes areas of water or land based on the terrain's water mask. #12149
• Fixed several bugs with PBR lighting for more realistic rendering. #12100, #12116, and #12118

See the changelog for the complete list of changes.

CesiumJS 1.120

2024-08-01

Highlights include:

• Added Transforms.computeIcrfToMoonFixedMatrix and Transforms.computeMoonFixedToIcrfMatrix to compute the transformations between the Moon's fixed frame and ICRF at a given time.
• Added Transforms.computeIcrfToCentralBodyFixedMatrix to specify the default ICRF to fixed frame transformation to use internally, including for lighting calculations.
• Added SplitDirection property for display PointPrimitive and Billboard relative to the Scene.splitPosition. #11982
• Fixed environment map LOD selection in image-based lighting. #12070
• Corrected calculation of diffuse component in image-based lighting. #12082
• Updated specular BRDF for image-based lighting. #12083

See the changelog for the complete list of changes.

CesiumJS 1.119

2024-07-01

Highlights include:

• Added Ellipsoid.default to allow a central place to specify a default ellipsoid value to be used throughout the API where an ellipsoid is not otherwise specified. #4245
• Various defaults have been updated to adjust when Ellipsoid.default is changed to a value other than the WGS84 ellipsoid.
• Fixed diffuse color calculation for PBR materials. Many models will now appear slightly brighter. #12043
• Fixed the calculation of base color in materials using the KHR_materials_specular extension #12041
• Adjusted spacing for on screen Credits and updated recommendations for positioning custom ones. #11912

See the changelog for the complete list of changes.
