[osg-users] osg::CoordinateSystemNode

[Filip Arlet]

Hi,

I'm working on a project for displaying geospatial data. I usually have data in some coordinate reference system. What I want now is transform them into another coordinate reference system (wgs84). Its not a big problem transforming coordinates on load or preparing data, but I would like to do it on the fly. Ie. keep data in one coordinate system and transfrom them to another. I found osg::CoordinateSystemNode but I cannot find any examples how to use it. Its CoordinateSystemNode class that I'm looking for? How to setup its params (preferably using Proj or GDAL or SRID) ? 

The transformation doesnt really have to be precise (I can always tranfer all data from one coordinate system to another if I want to publish data in different CRS, but supporting two coordinate reference systems at once would need to have data loaded twice).

Is this even possible ? I mean transforming coordinate systems using 4x4 matrix ?

Thank you!

Cheers,
Filip
