hello,
i am trying to feed opensg the tex coords for the cube map all by
myself. This means using 3 dimensional coordinates. On, no problem, I
think i should use GeoTexCoords3f.
I've copied a snippet of code from an example reading:
GeoTexCoords2fPtr txcrd = GeoTexCoords2f::create();
beginEditCP (txcrd, GeoTexCoords2f::GeoPropDataFieldMask);
{
txcrd->addValue(Vec2f(0, 1));
txcrd->addValue(Vec2f(0, 0));
txcrd->addValue(Vec2f(1, 0));
txcrd->addValue(Vec2f(1, 1));
}
endEditCP (txcrd, GeoTexCoords2f::GeoPropDataFieldMask);
so i told myself: great, just swap all 2s with 3s and you are done.
Wrong: all i get is a compilation error saying:
10loading.cpp:632: no matching function for call to `
osg::GeoProperty<osg::GeoTexCoords3fPropertyDesc>::addValue(osg::Vec3f)'
/usr/local/include/OpenSG/OSGGeoPropTexCoords.inl:138: candidates are:
void
osg::GeoProperty<GeoPropertyDesc>::addValue(GeoPropertyDesc::GenericType&)
[with GeoPropertyDesc = osg::GeoTexCoords3fPropertyDesc]
now what type of data should i use in the place of Vec3f?
finally my last question: since it is better to teach the hungry man to
fish, rather than giving him one fish, how can I guess myself what kind
of data is GeoTexCoords3fPropertyDesc? I've read the doxigen stuff and
gave a look at the src code, but didn't get very far...
thx enrico
