[Soc-2018-dev] Weekly report #06 - Implementing a Hair Shader for Cycles

[Brecht Van Lommel]

> I understand that this is a near-field shader, i.e. it should work fine at
> that level of resolution. I'm not well versed in the innards of Cycles, so
> I'd like to ask the community:
>
>    - Firstly, how can one set the measurement units so as to achieve
>    real-sized hair?
>    - What could be possible sources of the lack of definition the poster
>    mentioned? Could it mean a problem with the path tracer? Or is it a symptom
>    of noise caused by our shader?
>
> There may be precision issues with curve - ray intersection, or somewhere
in the BSDF. I'd ask the user for the .blend file and do some tests, trying
a different BSDF, zooming in close to see if there are visible artifacts,
etc.
