Version 2.6 (October 2014)

Release for maintenance. The release notes are to be determined.

Version 2.5 (November 2013)

Terrain engine

Terrain Engine ("MP") has undergone many performance updates. We focus on geometry optimization and GL state optimization, bypassing some OSG mechanisms, and go directly to GL to complete the task as quickly as possible.

MP has a new optional "incremental update" function. By default, when you change the map model (add/remove layers, etc.), OSGearth will completely rebuild the terrain. When incremental update is enabled, it will only rebuild visible shards. Blocks that are currently invisible (such as low-level blocks) will not be updated until they are actually visible.

cache

There are some improvements to the cache. The cache seeder (osgearth_cache) is now multi-threaded (just like the tms packager utility). The file system cache also supports expiration policies for cache items (including mapping tiles).

JavaScript

We updated osgearth to use the latest GoogleV8javascript interpreter API. We now also support javascriptcore as a JS interpreter for OSX/IOS devices (not available in V8).

Terrain effect

The new TerraIneffect API makes it easy to add custom shaders to the terrain. Osgerath has several built-in functions, including NormalMap, Detailtexture, Lodbinging and Contourmap.

New driver

There is a new Bing Maps driver. Bing requires an API key, which you can obtain on the Bing website.

We also added a new libnoise driver. It generates parametric noise, which you can use as terrain elevation data, or add fractal details to existing terrain, or generate noise patterns for detailed texture processing.
