关于worldPointToMapPoint

Elvies

好久没看osgearth了，发现osgearth2.4版本中osgEarth::Map的worldPointToMapPoint函数已经没有了，有谁知道这个函数改到哪个类里面了呢？

看osgearth论坛里维护人员gwaldron说把map里的一些接口都删掉了，相关功能再GeoPoint里可以找到，原话是：

A couple small API changes coming your way. These server to streamline the API and remove some redundancy.

The following Map methods will be removed since their functionality is now more completely served by the GeoPoint API:

    Map::toMapPoint
    Map::toWorldPoint
    Map::mapPointToWorldPoint

The corresponding methods in MapInfo will also go away as well.

Secondly, the Terrain getHeight methods will be simplified to contain only:

    Terrain::getHeight(srs, x, y, hamsl, hae)
    Terrain::getHeight(patch, srs, x, y, hamsl, hae)

..thus removing the variants that do not take an SRS, and moving the "patch" parameter to the front to avoid ambiguous parameter issues.

Enjoy.
