Hi Preet,

My personally recommendation would be to take things steadily with

Hi, Maurizio,
It probably comes from the fact that you're using ShapeDrawables for
your geometry. ShapeDrawable was never intended for serious work, and
as such, probably wasn't high on the list for support when OSG was
ported to work with OpenGL ES. If you converted your geometry to use
Hiya,
Thanks Robert and Chris for your insight and advice. I think I'll try
deploying using OpenGL ES 1.1 with what I have for now, and rebuild
the OSG stuff using shaders to eventually build with ES 2.0. As Robert
mentioned, this way I'll get a decent amount of exposure to GLSL and
the new
I would guess it has something to do with being repainted. It probably only

I have been working a bit in the new osg website (http://openscenegraph.com).
I am now creating all content categories and menu items. The amount of

maybe we need to split the main menu in vertical and top menus. I
If you're just using one overall color per drawable, try switching that
for an osg::Material with the DIFFUSE color set to the same color. You
might have better luck that way.

I think the problem could be that glColorMaterial is not supported in
OpenGLES 1.1. When you use ColorArray in a Geometry, I think it uses
glColorMaterial to enable lighting using the color of the geometry.
If you want to use Colors + Lighting in OpenGL ES 1.1, you need to
setup an

Thanks for the quick reply. I'm not sure whether the trade-off would be
beneficial, but what if VPB was modified to generate normal maps as the

Yes, it definitely sounds like a fairly large implementation task, but a
geomorph (as Shayne put it), seems like the most generic fix to the

Gles2 it goes all with shaders so if you don't rely on the default OSG
shaders, use your own, set uniforms as you like, etc it's pretty much
usable. There are still some glitches here and there that will be checked
when i can make a decent configuration to debug in Android.
