Hi,

floating point format of ILM goes opensource.

Does anyone want to put it in before siggraph?

Why ????

For digital film and grading it's fantastic, but to try and shoe-horn it into Blender's renderer as it stands would be a complete waste of time.

Who said anything about Blenders renderer?

Why ????

As I understand it blender has a floating point renderer (unified renderer) but all this data is trown away by saving 24 bit RGB images.

Not to mention it's other capabilities such as (paraphrased from an email on a list I read):

- lossless compression support with multiple codecs
- unlimited channels (for example. to save multiple Z depth information channels, alpha channels, etc)
- support for crop windows so that even though the render may be at 2K resolution, you only need to actually save the data for a small number of pixels, if your rendered object only takes up a small part of the frame
- metadata support like f-stops, lens types, etc. etc.
- direct support for fast hardware manipulation with commodity NVidia cards

Looks pretty darn good to me!

I'm not knocking it's abilities... I'm just saying that blenders current renderer would need a complete re-write to be able to make use of these features. By all means get stuck in and start codeing!!!
