Cycles OSL: most closure code is now shared between OSL and SVM. Also fix transmission pass and filter glossy option. The BSDF closure class is now more similar to the SVM closures, and includes some flags and labels that are needed to properly categorize the BSDF's for render passes. Phong closure is gone for the moment, needs to be adapated to the new structure still.

Fix for a case of 'static initialization fiasco' with OSL closure variables. The parameter lists are using OIIO::TypeDesc static standards, which are also static variables. With static OSL libraries these are not initialized when the closure parameter lists are initialized, so OSL rejects the closure types. Putting static initialization into functions works just as well, but ensures the OIIO::TypeDesc access is delayed until initialization is complete.

Cycles: 4 new nodes. * Tangent: generate a tangent direction for anisotropic shading. Can be either radial around X/Y/Z axis, or from a UV map. The default tangent for the anisotropic BSDF and geometry node is now always radial Z, for UV tangent use this node now. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Tangent * Normal Map: generate a perturbed normal from an RGB normal map image. This is usually chained with an Image Texture node in the color input, to specify the normal map image. For tangent space normal maps, the UV coordinates for the image must match, and the image texture should be set to Non-Color mode to give correct results. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Normal_Map * Refraction BSDF: for best results this node should be considered as a building block and not be used on its own, but rather mixed with a glossy node using a fresnel type factor. Otherwise it will give quite dark results at the edges for glossy refraction. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Shaders#Refraction * Ambient Occlusion: controls the amount of AO a surface receives, rather than having just a global factor in the world. Note that this outputs a shader and not a color, that's for another time. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Shaders#Ambient_Occlusion

Cycles OSL: diffuse_toon and specular_toon closures. These are toon shaders with a size parameter between 0.0 and 1.0 that gives a angle of reflection between 0° and 90°, and a smooth parameter that gives and angle over which a smooth transition from full to no reflection happens. These work with global illumination and do importance sampling of the area within the angle. Note that unlike most other BSDF's these are not energy conserving in general, in particular if their weight is 1.0 and size > 2/3 (or 60°) they will add more energy in each bounce.

OSL::ClosureParam *closure_westin_sheen_params();
Cycles: initial subsurface multiple scattering support. It's not working as well as I would like, but it works, just add a subsurface scattering node and you can use it like any other BSDF. It is using fully raytraced sampling compatible with progressive rendering and other more advanced rendering algorithms we might used in the future, and it uses no extra memory so it's suitable for complex scenes. Disadvantage is that it can be quite noisy and slow. Two limitations that will be solved are that it does not work with bump mapping yet, and that the falloff function used is a simple cubic function, it's not using the real BSSRDF falloff function yet. The node has a color input, along with a scattering radius for each RGB color channel along with an overall scale factor for the radii. There is also no GPU support yet, will test if I can get that working later.
