Hi,
Like everybody at some point of Engine
development we are thinking about implementing cloud system. We thought
about 2D array of boxes each one containing few cloud sprites. Of
course displaying all this at onece would be too taxing for the rendereres
so we would like to use impostors.
We thought that it would be nice if we could group
each neighbouring four cloud boxes under one impostor and each four neighbouring
impostor groups under parent impostor and so on building impostor quad tree
hierarchy.
We attempted to modify osgimpostor example to do
this but results are discouraging either no dispaly or very bad framerate. Is it
possible ? If so how ? Was impostor class
developed taking into consideration that its childrem may be another impostor ?
Will they properly depth sorting during impostor generation
?
Regards,
Wojtek Lewandowski
