Cheers

Hi Wojtek ,Thank you for your reply,I have tried GL_RGBA16F_ARB instead like that
"texture0->setInternalFormat(GL_RGBA16F_ARB);",but it seemed like not
valid.The value still is 0..1 range.Are there other solutions? Thank you.
So they are now _between_ 0 and , instead of 0 _or_ 1? Then, at least,
you're on the right track.
What seems wrong however is your sampler setup. Try this instead:
osg::Uniform* sampler = new osg::Uniform(osg::Uniform::SAMPLER_1D, "data");
sampler->set(0); //assign unit
ss->addUniform(sampler);
ss->setTextureAttribute(0/*unit*/, texture0 ,osg::StateAttribute::ON );
Cheers
Sebastian
