Hi all,
I have a HP 6730b (with the dreaded Intel 4 express graphics chipset, latest
driver, believe it supports GL2)
Guessing this is a driver bug, I am getting the following error when running
osgviewer srtm.earth:
Warning: detected OpenGL error 'invalid operation' at after
RenderBin::draw(..)
Digging deeper into the OSG debug output:
VERTEX Shader "osgearth_vert_setupTexturing" infolog:
No errors.

OpenGL extension 'GL_EXT_secondary_color' is supported.
OpenGL extension 'GL_EXT_fog_coord' is supported.

Also a bit further down the log:
draw() got SceneView 00D369F8
OpenGL extension '' is not supported.
Setting up osg::Camera::FRAME_BUFFER
draw() 00D362B8
draw() got SceneView 00D3C7F0
Created new 0FE1B330 TextureObject, _numOfTextureObjects 9
Snipped....
Created new 0FE1B330 TextureObject, _numOfTextureObjects 26
end draw() 00D363D0
OpenGL extension '' is not supported.
Setting up osg::Camera::FRAME_BUFFER
It does appear as an earth but with no textures, height data is applied to
the earth and shows ok, just no textures.
Anyone know why, it works ok on my Nvidia 480 desktop, guess this could be
an OSGEarth issue or the chipset driver is just naff?
Cheers
