The GL_RGB32F_ARB was a dangler ... I tried all sorts of options for that parameter. GL_LUMINANCE16F_ARB doesn't work things are more like they are now than they have ever been before -- Read this topic online here:

Hi, I've been trying to map a 32 bit float texture onto a quad for a while without success. Below is my code, can anyone tell me what I am doing wrong? This code opens a float32 image file, reads it into an array, creates an osg::Image with the array data, creates an osg::Texture2D with the

Hi Paul, I guess you have one channel float data. Certainly this is wrong: rImage->setImage( rawImage.rows(),rawImage.cols(),arrayDepth, GL_LUMINANCE, GL_RGB32F_ARB, GL_FLOAT, pData, osg::Image::NO_DELETE ); At least GL_RGB32F_ARB should be swapped with GL_LUMINANCE. First you pass internal
