hi dirk,
i assume that the normal skybackground works, for it displays all the
six textures. The only problem is that it isn't collecting their texture
coordinates. (my client collects them and rotates the textures
appropriately).
Using as example other tutorials i changed my code this way:
beginEditCP (MySky, MySkyBackground::TopTextureFieldMask);
MySky->getTopTexCoord().push_back(Vec2f(0,0));
MySky->getTopTexCoord().push_back(Vec2f(1,0));
MySky->getTopTexCoord().push_back(Vec2f(1,1));
MySky->getTopTexCoord().push_back(Vec2f(0,1));
endEditCP (MySky, MySkyBackground::TopTextureFieldMask);
where MySky is an object issued form the MySkyBackground class. in the
MySkyBackgroungBase.h i have the definitions of the various bit masks,
including the texture coordinates:
static const OSG::BitVector BackTextureFieldMask;
static const OSG::BitVector BottomTextureFieldMask;
static const OSG::BitVector FrontTextureFieldMask;
static const OSG::BitVector LeftTextureFieldMask;
static const OSG::BitVector RightTextureFieldMask;
static const OSG::BitVector TopTextureFieldMask;
So i think it *should* send those info to the server nodes. All the
other stuff is sent, as my scene is diplayed on the server windows, so i
assume the communication thing works just fine.
What changes should i apply to my code? i am still puzzled...
thx enrico.
