[osg-users] OSG Ellipsoid to Sphere Conversion

Hi Inna,

It still doesn't make a lot of sense, The ellipsoid model is to abstract 
geographic coordinates to geocentric coords. Lat, long however is 
spherical coordinates and can be mapped to an ellipsoid...
So please try  to rephrase your question: What is it what you want to 
do, or present some code that is not working for you.

Cheers
Sebastian

I want to do the same with same Sphere. But I dont have idea how to do with sphere the same thing. I want to make sphere with radius which varys basing on the screen coordinates. In osg::Sphere I can see setradius(), but how can i set radius to screen coordinates ?
