Hi,
Imagine a Program which lets you do a wide variety of ways to edit, alter,
enhance and process batch conversion of your pictures in just a few clicks.
Batch Image converter is the easiest to use programs that can apply your
desired option to all or selected pictures at once...

Thanks, hybr. But I still do not know why the values in the image attached to

to see a lot of variance between the top and bottom portions of the image,
given that the top portion would be covering the sky, and the

Hi Randall,
The flickering issues is very unlikely to be related to culling as
it's naturally thread safe thanks to the way it's effectively buffered
and hasn't caused problems before. The exception to this would be if
you have some cull callback that is't thread safe, or you are using
something

Hi Tina,
Setting the colour array on an osg::Geometry should be quick and
shouldn't normally make rendering slow. The fact you are finding this
suggests that perhaps you are setting up osg::Geometry to render with
OpenGL slow paths so as using indices arrays or per primitive bindings

Maybe would be easier to do a client-server approach to give orders to the
