Hi Phillipe,
nice to hear that the 3dl support made some progress. Sadly it is not
possible for me at this time to compile from source because i am tight
in time. But if you, or anyone else, can send me a compiled version
(Win64) i will be happy to test it against all 3dl files i have.
Regards
Jan

Hi Jan,
I've made a try to implement 3dl files. see PR #4096.
Your references and your code helped me a lot.
That works for me (your 3dl file plus those from the link given by Guido), but
I haven't a lot of them to test. If you have the possibility to build that PR
and give me a feedback that would be great.
Thanks
Philippe

Hi Jan,
I haven't found the specification of 3dl file but I understand the coordinates
of the cube can be non linear.
That's the role of the first line of data (0 64 128 192 256 320 384 448 512 576
640 704 768 832 896 960 1023 for 17 vertices in your sample file).
I've read that we could even have 3 lines like this, one per axe.
If I've understood properly, the lut3d transfer function is not able to do that
today.
Regards
Philippe

Attached an example 3DL-file and the source of LUT-Import from my
Irfanview-Plugin.

Any plans to extend it to the compressed 3D-LUTs?
Just merged (3.0.1)
Is it possible to integrate the compression of HALDCLUT- and
CUBE-files? Possible a button 'Compress-3D-LUT"?
Compression is a really long process and so far it has been kept
outside dt. See GMIC commands for that.
Please add additional formats for the 3D-LUT files: tif and 3dl
Could you share the sites providing such lut formats ?
