Re: [osg-users] Coordinates in VPB database

Thank you all for your help...that got me going in the right direction. Essentially what I did was traverse the scene graph to find my osg::CoordinateSystemNode, get the osg::EllipsoidModel from it and then use it to transform my desired LLA point to world coordinates: Code: double lat =

[osg-users] Coordinates in VPB database

Pardon the elementary question...I'm a newbie with OSG and VPB. I've search around but haven't found a simple example that illustrates what I'd like to do. Essentially, I've built a VPB whole-earth database and got it loaded in my application. There are two things I'd like to do at this

Re: [osg-users] Coordinates in VPB database

Re #1: Your whole-earth database is in geocentric (earth-centered XYZ) coordinates. In the class osg::EllipsoidModel (in osg/CoordinateSystemNode) there are functions to convert from lat/long to geocentric and back. You can these to calcuate the XYZ at which to place your model. Then use the XYZ
