Hi Roman,
Have you tried just casting data to unsigned char* ?
data = new float[256*64*3];
f = fopen("data/transmittance.raw", "rb");
fread(data, 1, 256*64*3*sizeof(float), f);
fclose(f);
osg::Image* image_Transmittance = new osg::Image;
image_Transmittance->setImage(64,16,1, GL_RGB16F_ARB, GL_RGB16F_ARB,
GL_FLOAT,(unsigned char*) data, osg::Image::USE_NEW_DELETE);
