Hello everyone,
I'm using a plugin to read OSG nodes in .gz files I developed on my own. It
works perfectly well, but now I would like to use this plugin with the
DataFilePathList handling system in osgDB and I can't get it working this
way... I tried something like:
osgDB::FilePathList

Hello everyone,
Currently, I'm developing a program where I have to display an Earth
model... to perform this I use :
- a big sphere shape...
- a dds texture of 4096x2048 for day time
- another similar texture of 4096x2048 for night time
- a cloud texture of ... 4096x2048 :-(
- another normal
No osgdem would not be enough : some of the textures I use can change
dynamically, how could I use them on osgdem tiles, the uv coords would
hardly correspond, no ?

Emmanuel.
