I don't know if this is the whole problem, but this use of the Uniform
constructor does not give the uniform binding the correct type. You need to
do something like this:
Uniform* texSampler = new Uniform(Uniform::SAMPLER_2D, "uTextureMap");
texSampler->set(0);
m_geode->getStateSet()->addUniform(texSampler);
m_geode->getStateSet()->setTextureMode(0,GL_TEXTURE_1D,osg::StateAttribute::OFF);
