Changelog

v 1.21 -

  • Changes
    • Add olcs.OLCesium.trackedFeature property to make Cesium automatically track an OpenLayers point feature. When active, the Cesium camera will follow changes of the feature position. This requires using stacked view.

v 1.20 - 2016-09-02

  • Changes
    • Port to Cesium 1.25.
    • Port to OpenLayers 3.18.2.

v 1.19 - 2016-08-08

  • Changes
    • Require node 4 or 6.
    • Port to Cesium 1.24.

v 1.18 - 2016-07-18

  • Changes
    • Port to Cesium 1.23.
    • Port to OL 3.17.1 (include OL3 typedefs.js and rename some symbols).
    • In examples, use OSM instead of obsolete MapQuest tiles.

v 1.17 - 2016-06-23

  • Changes
    • Port to Cesium 1.22.
    • Add olcs.core.convertUrlToCesium function to help convert OpenLayers urls to Cesium.
    • Handle arbitrary line widths on Windows OS.

v 1.16 - 2016-05-30

  • Changes
    • Switch to eslint.
    • Update npm dependencies.
    • Port to Cesium 1.21.
    • Port to OL 3.16.0.
    • Add support for drawing rectangles according to the longitude and latitude curves instead of straight lines. This functionality can be activated by setting the olcs.polygon_kind property to 'rectangle' on the OpenLayers geometry.
    • Add support to set a proxy for Cesium to load layer not accessible due to missing CORS headers (eg. when user can't modify configuration of the mapservice used). This functionality can be activated by setting the olcs.proxy property to the OpenLayers source.

v 1.15 - 2016-04-28

  • Changes
    • Use fast pixelated canvas scaling on supported browsers. See PR 3288 / commit 322df7b in Cesium. On unsupported browsers, render at full resolution (slow).
    • Port to OL 3.15.1.
    • Port to Cesium 1.20.

v 1.14 - 2016-03-31

  • Changes
    • Accept a mode=dev parameter in examples to ease debugging.
    • Port to OL 3.14.2.
    • Port to Cesium 1.19.

v 1.13 - 2016-02-29

  • Changes
    • Port to Cesium 1.18.
    • Port to OL 3.14.0.

v1.12 - 2016-01-30

  • Breaking changes
    • Remove dragbox functionality due to the removal of the Cesium.RectanglePrimitive by upstream. See the commit message for hints about how to reimplement it.
    • Remove Cesium.RectanglePrimitive, Cesium.PerspectiveFrustrum.getPixelSize, Cesium.OpenStreetMapImageryProvider from Cesium externs.
  • Changes
    • Port to OL 3.13.0.
    • Port to Cesium 1.17.

v1.11 - 2015-12-23

  • Changes
    • Port to Cesium 1.16.
    • Port to OL 3.12.1

v1.10 - 2015-11-30

  • Breaking changes
    • OL3-Cesium is now compiled together with OL3. A custom closure compiler build is no more required.

v1.9 - 2015-10-22

  • Breaking changes

    • Port to OL 3.10.1, remove saturation, gamma and hue functions.
    • Change olcs.AbstractSynchronizer.prototype.createSingleCounterpart to return an array of counterparts instead of a unique object. This allows one OL3 layer to be transformed in several Cesium layers.
    • Rename olcs.AbstractSynchronizer.prototype.createSingleCounterpart to olcs.AbstractSynchronizer.prototype.createSingleLayerCounterparts.
    • Rename olcs.RasterSynchronizer.prototype.convertLayerToCesiumImagery to olcs.RasterSynchronizer.prototype.convertLayerToCesiumImageries.

  • Changes

    • Add olcs.OLCesium.setResolutionScale to allow improving performance at the cost of quality.
    • Automatically use device pixel ratio to configure the Webgl 3D globe.
    • Add the experimental method olcs.OLCesium.enableAutoRenderLoop to stop rendering the globe when idle. This is based on work from Kevin Ring.
    • Port to Cesium 1.14.
    • The olcs.AbstractSynchronizer now tries to synchronize the layer groups. Only if null is returned will it synchronize each of its children. This allows more synchronization strategies in user applications.

v1.8 - 2015-09-10

  • Breaking changes

    • Rename olcs.core.OlLayerPrimitive to olcs.core.VectorLayerCounterpart and stop inheriting from Cesium.PrimitiveCollection. The underlying primitive collection may be retrieved with the getRootPrimitive() method.

  • Changes

    • Port to Cesium 1.13 and OL 3.9.0.
    • Allow blocking Cesium rendering to save resources using olcs.OLCesium#setBlockCesiumRendering(true).
    • The build/generate-info.js tool now follows symlinks to properly generate exports.
    • olcs.RasterSynchronizer.prototype.convertLayerToCesiumImagery may be overriden. As usual, subclassing requires that the subclass and the library code be compiled together by Closure. This change notably allows application code to handle projections not supported by Cesium.
    • Allow application developers to easily compile plugin code together with the library by putting their files in the src/plugins directory. See src/plugins/README.md for details and instructions.
    • Allow lazy loading of the Cesium script (experimental feature).

v1.7 - 2015-08-07

  • Port to Cesium 1.12 and Ol 3.8.1

v1.6 - 2015-06-30

  • Breaking changes
    • The layer is now passed to the conversion methods of ol.FeatureConverter.
    • The feature is now passed to the conversion methods of ol.FeatureConverter.
    • The olcs.core.olVectorLayerToCesium() function now takes a scene parameter. The olcs.core.OlLayerPrimitive constructor now takes a scene parameter.
    • Core static functions for converting from OL3 features to Cesium primitives have been moved into a class designed for inheritance. The olcs.FeatureConverter may be extended and passed as a parameter of the olcs.VectorSynchronizer constructor. See the synchronizer function parameter of the olcs.OLCesium constructor. Subclassing requires that the subclass and the library code be compiled together. One way of migrating existing code is to define a global variable: app.converter = new olcs.FeatureConverter({scene: scene}); and call the methods through it: app.converter.olLineStringGeometryToCesium().
  • Set reference to the OpenLayers feature and layer to all created Cesium primitives.
  • Compiled code may override the new olcs.FeatureConverter.csAddBillboard method in order to manipulate the option before the Cesium billboard is actually created.
  • The layer is now stored together with the feature in the Cesium counterpart. They may be retrieved using pickedCesiumPrimitive.olLayer and pickedCesiumPrimitive.olFeature.
  • Position point geometries on terrain. With 2D coordinates, use pointFeature.getGeometry().set('altitudeMode', 'clampToGround'). With 3D relative coordinates, use pointFeature.getGeometry().set('altitudeMode', 'relativeToGround').
  • Port to Cesium 1.10.

v1.5 - 2015-05-29

  • Port to Cesium 1.9 and Ol 3.5.0

v1.4 - 2015-04-30

  • Port to Cesium 1.8 and Ol 3.4.0
  • Mark olcs.RasterSynchronizer @api

v1.3 - 2015-03-23

  • Breaking changes
    • The enable argument to olcs.OLCesium#setEnabled() is no longer optional.
  • Port to Cesium 1.7.1 and Ol 3.3.0

v1.2 - 2015-02-25

  • Port to Cesium 1.6 and Ol 3.2

v1.1 - 2015-01-20

  • Breaking changes
    • The olFeatureId has been removed from the picked Cesium counterpart. Use directly olFeature as illustrated in the synthetic vector examples.
    • The olcs.OLCesium constructor signature has changed. Use new olcs.OLCesium({map: map, target: target}); instead of new olcs.OLCesium(map, target);
  • Custom synchronizer function may be passed to the OLCesium constructor
  • Core functions for implementing custom 2D-3D transitions à la Google Map
  • Store the ol.Feature in the Cesium counterpart instead of an id. Use primitive.olFeature to read it after picking. See the synthetic vector examples.
  • Allow 3D warmup while displaying the 2D map

v1.0.0 - 2014-11-17
