Hi Jayce,
It won't work in GLES1 nor GLES2.
See documentation in particularities of OSG on Android section.
Cheers

Thank you!

Hi Jonathan,
Is there a reason why you haven't considered using the new osgQt
library, now part of the OpenSceneGraph-3.0 release? The osgviewerQt
example illustrates it's usage.
Robert.

Hi, Jordi
I read the doc, it says:
* OSG in Android only supports Static linking.
* OSG needs to be compiled with OpenGL ES 1.x OR 2.0
* Environmental mapping doesn't work.
* Automatic Shaders don't work.
* Multithreading Handler doesn't work.
* osgSim and osgShadow won't
Thanks for all these clarifications !
About the plugins : where can I find specific plugin license ?

Hi Jayce,
The texture in the model cow.osg does not work because it makes use of
*environmental
mapping textures*. If you want to show environmental mapping textures you
can code a shader to do it. In GLES1 not all OpenGL is supported and in
GLES2 you need some experience in shader composition.
Hi,
thanks for your answer. noRotation works, but for some reason he always makes
tri strips, which I want to avoid.
I tried this:
Code:
osgDB::ReaderWriter::ReaderWriter::Options* options = new

options-setOptionString(noRotation
Thanks for the update Torben. I'll keep you posted on our descision and
hopefully progress after that

Hi All,
I'm investigating the NVidia Uniform array issue, there have been some
suggested changes that address these but only copy and pasted into
emails. Could you send me the complete modified files so I can review
them as this will avoid any possible ambiguities.

The fact that the ModelView matrix is often modified isn't the correct way to
look at the problem - we need to consider how the system behaves when it is the
identity.

Hi,
As far as I know it's not explicitly specified but is implicit in the
projection transforms. Assuming the ModelView matrix is the identity, the
matrices generated by the traditional Ortho/Frustum functions would result in a
vertex's Y value determing its height on the screen. That scenario

There's no reason to pay any attention to the default orientation, since
you can change that with a simple transform concatenated into the dozens of

That is accounted for in the viewport transform, not inside OpenGL itself.
Coming into this thread rather late, and didn't read all the posts, but it's
clear that there's a fundamental misunderstanding of the FFP transform here...
