Hello Christian
My problem is that the clouds are supposed to become part of my depth
peeling algorithm for achieving proper transparency, and hence I
cannot just draw them after everything else ;)
I see.
I need to draw the clouds without any alpha blending enabled, because
the depth peeling will blend the clouds into the final scene
afterwards. The blending done by DrawObjects(true) causes the clouds
to turn very dark at the edges in my use case.
I just asked the Sundog support, because after purchasing the SDK I
think there's 3 months of support included. Do you know if they also
have a user forum?
I didn't find a forum. But they also answer questions from
non-customers, and Mr. Frank Kane is quite responsive.
cheers

Hi Christian,
If you are referring to drawing the clouds individually:
I had exactly the same problem and didn't find a solution apart
from rendering the clouds after everything else. (simply using the
DrawObjects approach) as I thought I'm simply stupid.
But maybe simply drop a line to support@sundog, they really helped
a lot with those issues.
Also it is worth upgrading from time to time, as they seem to
release a new version quite regularly.
If you get some answer/solution I'd be interested, too
cheers
Sebastian
Hi,
I have the need to draw the silverlining clouds without alpha
blending enabled. So I use DrawObjects(false) in order to roll my
own cloud drawing. I tried to follow the sample posted here:
http://www.sundog-soft.com/docs/html/usage.html
Under "Here's an example of manually drawing clouds following a
call to Atmosphere::DrawObjects(false):" this guide contains some
OpenGL snippets.
But it seems the call to atm->DrawObject(*it) is messing with the
OpenGL state so badly, that I don't even see anything on screen
any more afterwards. I tried saving and restoring most OpenGL
states around this function call but got funny sparkling clouds
in bizarre colours.
I was just wondering if anyone can offer a working example of an
OSG silver lining integration with running DrawObject() for
clouds in the drawImplementation of a drawable.
Christian
