[Soc-2013-dev] Weekly report #7 Cycles nodes

[Thomas Dinges]

Hi,
here my report for week 7: 
http://wiki.blender.org/index.php/User:DingTo/GSoC_2013/Weekly_Reports/Week7

= Week 7 =

== What I did this week ==
* Brecht reviewed my branch this week (thanks a lot Brecht) so I could 
work on getting some things into trunk. I fixed some things in my branch 
which came up in the review (Blackbody node, Ray Depth, Vector Transform 
node...), and also added a new type for the Vector Transform node, which 
is "Normal".

* I merged the Blackbody Node, Vector Transform node, HSV 
Combine/Separate nodes and the Ray Depth shading feature to trunk.

* SSS Render Passes: I changed some variables there, which also came up 
during the code review and commited that. Brecht also gave me a hint how 
to proceed further. I have some (uncommitted) changes, which I hope to 
improve this weekend.

I also spend some time on trunk Cycles:
* Added Presents to the Sampling panel, so people can quickly jump 
between render settings for final/preview purposes.

* For the Non-Progressive integrator there is a new "Squared Samples" 
option which Matt Heimlich implemented (I just did some small tweaks), 
so the user can more easily tweak the sampling values. The idea here is, 
that increasing samples from e.g. 80 to 82 is not noticeable, a increase 
from 8*8 to 9*9 on the other hand is. This makes it easier to adjust and 
tune the different amounts of Sample types, to get a satisfying result.

* Found a small improvement for Non-Progressive integrator, basically 
removes an if-branch to avoid checking for Transparent BSDF in one loop, 
which is not needed.

== Next week ==
* Continue on SSS render passes and hopefully some progress with the 
Motion Multiplier, which I have to admit is still a bit of a mystery for 
me.

== Questions ==
None.

Best regards,
Thomas
