Hi,
here my report for the fifth week of GSoC:
http://wiki.blender.org/index.php/User:DingTo/GSoC_2013/Weekly_Reports/Week5
= Week 5 =
== What I did this week ==
* Vector Transform node: I did some cleanup to avoid unnecessary
conversions of strings (lower/upper case) in the OSL implementation.
* Blackbody node: I fixed the weird colors with 800-804.4 Kelvin, this
was a lookup table offset issue. I made the table slightly bigger, so we
have a small gap between the R/G/B values.
* I started with the Object Motion Multiplier, to weaken/strengthen the
motion blur effect on a per object basis.
** Work in Progress patch: http://www.pasteall.org/44182/diff
** This is not working the way I'd expect the feature to work yet. I am
passing the shuttertime*multiplier to the compute_bounds() function,
but this has not the same effect like changing the global shuttertime.
** While working on this, I found it would be a nice feature as well, to
be able to disable Object motion blur on a per object basis. By Setting
the Motion Multiplier to 0.0, object->use_motion is set to false. Should
probably be a Boolean Checkbox later on.
* I started thinking about the SSS render passes, but do not have a
clear idea yet how to handle those. I assume SSS still falls under the
Diffuse Ray category? Maybe add a new variable to the PathRadiance struct?
* Apart from that I worked a bit on the bug tracker, due to the 2.68
release.
** Fix for #36150, missing Preview Render Updates with Add/Remove
material slot.
** Possible fix for [#36086] Activating the opencl option in the
compositor causes blender crash
** Fix for [#36216] Viewport render with CMJ sampler and unlimited
passes freezes
== Next week ==
I will continue working on the Motion Multiplier feature.
Apart from that I am not sure how much time I can spend on GSoC next
week, as we have German BlenderDay conference next weekend, and I am one
of the organiser there.
== Questions ==
Yes, feedback on the Motion Multiplier patch would be appreciated.
Best regards,
Thomas
