It would be nice to have the ability to provide detailed light intensity distribution information via IES data.

On a related note: is there any pbrt example that uses the goniometric light source? The description in https://pbrt.org/fileformat-v4 is perhaps too simplified, and I can't seem to find any example of the goniometric image file that stores the goniometric diagram on the web.
