?This is far from trivial. There is deep transform in Nuke, but it does not do 
any filtering and i am not sure there is a meaningful way to do that.


Cheers,

Thorsten

Betreff: Re: [Oiio-dev] Deep merge

There's not currently a function in OIIO that does this. Does Nuke have deep 
resize? I guess it's theoretically possible, though you'd need to do a little 
math to figure out the right way to combine partial/filtered pixels, where each 
"pixel" is a list of depth+alpha samples.

Also! Are there methods of resampling a deep image?  If my B image is a 
different resolution than my A image/the pixel count is different, it would be 
nice to still be able to merge them together.

Thanks!

Hi!

I'm looking at wrapping up a deep merge operation using the python bindings of 
oiio 1.7.

I see in the docs that there is support for reading and merge deep pixels.  Is 
the expected workflow for all deep images to loop over every pixel?  Is there a 
function I've overlooked that might do a deep merge for all samples in the 
image?

Wouldn't this mean that it's essentially single threaded to do a deep merge in 
python without setting up the threads myself?

Thanks!
Ben
