Hi all,
I am a new bie here. I was playing with some examples. From the FadeText
Example
http://trac.openscenegraph.org/projects/osg//browser/OpenSceneGraph/trunk/examples/osgfadetext/osgfadetext.cpp
. In this example, I have the ellipsoid model from the lat, long and height.
It's clear, then I tried to change this to Sphere. For me it seems, not
possible to convert the Elliposid to sphere.
Code:
osgText::Text* createText(osg::EllipsoidModel* ellipsoid, double latitude,
double longitude, double height, const std::string& str)
{
double X, Y, Z;
ellipsoid->convertLatLongHeightToXYZ(osg::DegreesToRadians(latitude),
osg::DegreesToRadians(longitude), height, X, Y, Z);
osgText::Text* text = new osgText::FadeText;
text->setDrawMode(osgText::Text::TEXT |
osgText::Text::BOUNDINGBOX);
osg::Vec3 normal = ellipsoid->computeLocalUpVector(X, Y, Z);
text->setCullCallback(new
osg::ClusterCullingCallback(osg::Vec3(X, Y, Z), normal, 0.0));
.......
I am out of ideas, to do this possible to make same thing with sphere. Could
youe please some one help me to do this.
thanks and cheers,
Inna [/code]
