[Bf-cycles] Brick Texture for Cycles (Patch)

Thomas Dinges blender at dingto.org
Tue Aug 21 20:25:34 CEST 2012


Hi Brecht,

Welcome back! :)

I implemented a Brick Texture Shader for Cycles, based on the BI 
internal one. It has several options to tweak the look of the bricks.
I attached a patch.

Picture of the Texture: http://temp.dingto.org/brick_texture5.png

ToDo/Bugs:
* There are some input sockets, which are passed over to the shader as 
expected, but I have problems with the 2 float RNA values.
See nodes.cpp, I have offset = 0.5f; and squash = 1.0f; I can't find a 
way to pass those 2 values to the svm code correctly.
The other two values coming from RNA (offset_frequency and 
squash_frequency) work fine, but they are integer.

* The Texture only works fine on X vector, y and z have issues, but 
that's the same limitation as in the BI Brick node.

Could you take a look / review please? :)

Best regards,
Thomas
