[Linux] Eyesight on Linux

[Eugen]

There's no repo, the page is linked in the forum post.

Maybe, I don't know as I'm not logged in into BrickLink (and forum is not public).

But on BrickLink public site there is no info on open-source parts of BL Studio, except for the FFMPEG (LGPL-licensed), that is mentioned as used by render (i.e. by Eyeseight):

• https://studio.download.bricklink.info/S...-4.0.2.zip
  

And nothing about Eyeseight licensing (Cycles render source is under Apache 2.0, that has been changed from GPL in 2013), and there was no announcement on releasing the source in a form of public blog or news post elsewhere except here and in the same thread on Eurobricks, which are based on non-public BrickLink forum post.

There was also a 2021 thread on Blender DevTalk, unveilng that they even included bits of GPL-source in closed source BL Studio (not sure it was just in Eyesight render, or in another part of BL Studio): https://devtalk.blender.org/t/on-what-ve...ased/17566

Got bored, did some digging in their binary, they built using some of our our svn libraries (I know it’s our libs since the paths embedded for some of the source files are local to my computer light_smile: ) which makes it easy to track down

they ship openimageio 1.7.15 which means the code is likely from somewhere in between 2017-06-04 and 2018-08-27 which is indeed around the 2.79 time frame.

It would have been nice if they kept the code opensource, so it could get all the improvements blender makes easily, but they seemingly chose not to go that way. which is somewhat strange since they clearly lifted the GPL licensed bf_blenlib [1] so the closed source nature of eyesight is odd to say the least.

[1] the executable contains strings like

Code:

Error! Could not get the Windows Directory - Defaulting to Blender installation Dir! , Error! Could not get the Windows Directory - Defaulting to first valid drive! Path might be invalid! and BLI_dynstr_append text too long or format error.

that can only could have come from bf_blenlib

Anyway, link to https://blstudio.s3.amazonaws.com/Eyesight/Eyesight.zip and http://slswww.free.fr/build_linux.html should be added into Eyesight's page on LDraw Wiki.

Also, the "How to" article and linked files in it should be backuped while they are accesible now.
