Hi All! I have very specific problem which I don't know how to solve with OSG.
I want to create very large texture atlas (4096x2048) which consists of small subtextures (128x64, so there are 32x32=1024 subtextures). Each of small textures should contain some textual/symbol information which is supposed to be frequently updated in the runtime. I use Qt to compose QImage with rendered text/symbols and I want to update some subtexture (given by offsets in x and y with constant size) of the the texture atlas with prerendered data. I know how to achieve this with pure OpenGL (using PBO and glTexSubImage2D), but I can't figure out if there is a way do this with OSG? Maybe subclassing osg::Texture2D or something? Thank you!
