Hi,
For all, I made a small package with the textures I used in the video- there
are more to come and more shaping of the clouds.
You can take a look here:

Yep- and so much as I know it is on the To-Do-List of Stuart

One thing that Mark Harris' clouds considered was lighting I believe.
Portions of the cloud that were shaded were darker and portions of the cloud
most exposed to the sun light were lighter. I don't know the exact
algorithm, but I believe he was doing some extra work with lighting. Then

The cloud code does a single bubble sort pass per frame, to avoid the
performance penalty of sorting the entire cloud set each frame.
We could do something similar f

Thanks to all of you working on 3d clouds. I have assembled some in flight
pictures showing various types of clouds that might aid in creating textures.

If thereis'nt other cloud layers, looks great from any angles, thanks!
If any other cloud layer above, then from ground look same as without patch
:(
Now time to tune textures and xml, maybe

Hi Stuart,
Attached is a small fix for the sorting in CloudShaderGeometry.cxx.
I think the sorting problem stems from the osg idiosyncracy
to store transposed matrices...so the intuitive
osg::Vec4f p = vm * osg::Vec4f(_cloudsprites[i]->position.osg(), 1.0f);
needs to be replaced with...

Works fine for me!
I don't test much, but can say, that fps with 3Dclouds drops now from 50 to
30 instead 50 to 1
43 matches
