=== BlenderArtists community survey ===

bzztploink on IRC suggested:

<blockquote><code>2018-04-24 16:12:01 bzztploink you could also think about having a thread on blenderartists.org so people can follow your progress and give feedback</code>
</blockquote>
Thread is [https://blenderartists.org/t/cycless-gsoc-2018-project-new-hair-shader-expectations/1103070/10 here].

Summary:

* A substantial number of users asked if the end result would be a principled shader (à la [http://blog.selfshadow.com/publications/s2012-shading-course/%5D Disney über-shader]).
** Brecht says this will be indeed the case:
<blockquote><code>2018-05-07 17:44:29 brecht I didn't mentioned it explicitly, but the idea was for the new hair shader to be called "principled hair"</code>
</blockquote>
<blockquote><code>2018-05-07 17:44:41 brecht so that we have principled bsdf/hair/volume</code>
</blockquote>
<blockquote><code>2018-05-07 17:44:52 brecht and user will then immediately understand it's an "ubershader" type thing</code>
</blockquote>
* There were a number of complaints about:
** The lack of documentation on the current shader. There is no explanation on how to setup a proper hair material, only the physical meaning of the parameters and that’s it.
** The usability of the current shader. Some artists try to make the most of it by using complex nodegroups, but that’s a stopgap measure at best.
* The primary concern was about the shader’s interface:
** Would the modes (R, TT, TRT) stay separated?
** Intuitive parameters

=== Development environment preparation ===

I’ve setup MS Visual Studio 2017 on Windows 7 x64. I had CUDA installed from an earlier postgrad course, so no news on that front.

I tried to follow [https://wiki.blender.org/index.php/Dev:Doc/Building_Blender/Windows the BlenderWiki page] on the subject. The make script finds only the 32-bit toolchain, even if called from within the 64-bit Build Tools CLI. I ended up following [https://wiki.blender.org/index.php/Dev:Doc/Building_Blender/Windows#Manual_CMake_Setup Manual CMake Setup] to force a fully x64 build toolchain, using the CMake GUI to finish off the process.
