But i am still wondering what does these features intend to do, By multiple layers do you mean that on a given height field we can enable or disable different textures during runtime, for example i have two images one shows the population density on heighfield and other is a regular landsat image of the same height filed then by using this feature i can create my database with two layers one with each texture and then can switch between these images during runtime.
Multiple layers means multiple colour layers which maps to multiple texture units being used. osgTerrain is principally a framework for runtime rendering support for terrain data, so switch between data will be possible if supported by the TerrainTechnique used to the render the terrain. Its early days for osgTerrain so we only have GeometryTechnique so far which is brute force approach to rendering a height field. GeometryTechnique will support dynamic update of the layers, but doesn't right now.
