Are there any file formats that natively handle floating-pt RGBA values?
I’m looking for one that can be handled by osgDB read/writeImageFile where
the data is stored in a format such as GL_RGBA32F_ARB (and preferably can be
viewed offline by some generic viewer provided the values are in the
[0,1] range).
I can read/write them raw, but would prefer something standard if it exists.
Thanks,
Bill
