Hi all!
I have found some docs about animating a textured object using texture3D.
So I have tried to do it myself but it doesn't seem to work, it freezes on a
single noise 2D texture.
I use Perlin Noise to build dynamically the texture. Then I pass it to the
fragment shader. I managed to write

As a hint. I have found that the size of the written image is far from being
right. It seems to be a 256*256*1 image rather than a 256*256*256 image.
It weights 257ko which is nearly the same as 4*256*256 (4 for rgba)

OSG is a DAG http://www.vis-sim.com/imgdp/dagb.jpg
Which means every node has at least one parent expect the Root node
In your case 'C' would never get traversed with the standard OSG
traversers unless you provide all your own traversal routines

Seems the dominance warnings are because the class inherits from two
classes that define the same member...
Yes having 2 members could be a big issue errr uhmm ohh

I assume that the above methods involve SpeedTree prior to v5, which
is what I am using. According to the SpeedTree website v5 includes a
reorganization of the SDK. How much, I do not know, but maybe someone
has experience with it and OSG.
I hope you get some answers about this, I
