[Soc-2013-dev] Weekly report #2 Cycles nodes

[Thomas Dinges]

Hi,
here my report for week 2: 
http://wiki.blender.org/index.php/User:DingTo/GSoC_2013/Weekly_Reports/Week2

= Week 2 =

== What I did this week ==
* I continued work on the Vector Transform node, adding the initial 
Cycles implementation. It only works in the OSL backend for now, SVM 
implementation is still missing. See my questions below.

* Outside of my GSoC work, I spend some time on trunk and preparations 
for the upcoming release (Update OSL to 1.3.2 on Windows, fix some bugs, 
going over tracker to confirm/close reports...)

* Apart from that, I focused on exam preparation this week.

== Next week ==
I have an exam on Wednesday, so I will focus on that for half of the 
week. I hope to finish the Vector Transform node by the end of next week 
though, then I would be finished with the nodes part.

== Questions ==
I am not sure about the Vector Transform SVM implementation yet. The 
Cycles todo list mentions, that those matrices are available but I 
couldn't identify the correct ones yet. In the KernelCamera struct there 
are some Transform data types, like "cameratoworld", also the Camera 
struct in /render has some. I figure that in SVM it's not a simple 
function call to convert to/from, but I have to use those transform 
types. Some hints on that would be appreciated.

Best regards,
Thomas
