To make a generic OSL shader connectable to other nodes, the parameters
must be declared via "input" and "output" child elements:
<osl_shader name="tex" src="./osl/stripes.osl">
<input name="Stripes" type="int" />
<output name="ColorOut" type="color" />
</osl_shader>
`name` must be the same as the OSL shader parameter name.
`type` must be one of float, int, color, vector, point, normal, closure,
string (matching cycles socket types)
Beyond this the OSL script nodes then work just like all other nodes.
OSL parameter sockets can be connected to other cycles nodes:
<connect from="checker color" to="tex Stripes" />
<connect from="tex ColorOut" to="floor_closure color" />
They can set default values for the input sockets by attributes of the
main node element:
<osl_shader name="tex" src="./osl/stripes.osl" Stripes="3" >
<input name="Stripes" type="int" />
<output name="ColorOut" type="color" />
</osl_shader>
This system of specifying custom attributes should probably be changed,
since it can easily create name conflicts and arbitrarily long elements.
But that is a different issue to be solved for all nodes in general.
Indirect and Direct samples can now be clamped individually. This way we can clamp the indirect samples (fireflies), while keeping the direct highlights.
Example render: http://www.pasteall.org/pic/show.php?id=66586
WARNING: This breaks backwards compatibility. If you had Clamping enabled in an old file, you must re-enable either Direct/Indirect clamping or both again.

* Very simple implementation, only allows for 1 output socket. As we haven't decided yet whether we keep the XML API, rather not spend more time on this now.
* To use an external osl shader, put the .osl file next to the xml file.
* Parameters: "output" is the output socket name, "output_type" the variable type (float, color and closure color are supported).
Example:
<osl_shader name="tex" src="ramp_closure.osl" output="Phong" output_type="closure color" />
<connect from="tex Phong" to="output surface" />
* Change Info in header, put more important info to the left
* API: Move Camera width/height to camera, add some film properties
* Add ESC key to help menu
This is very basic for now, but can be extended with more info (available devices for example) later.
Thanks to Bastien and Sergey for some help with the glRect coordinates stuff.
* Henyey-Greenstein scattering closure implementation.
* Rename transparent to absorption node and isotropic to scatter node.
* Volume density is folded into the closure weights.
* OSL support for volume closures and nodes.
* This commit has no user visible changes, there is no volume render code yet.
This is work by "storm", Stuart Broadfoot, Thomas Dinges and myself.
This actually works somewhat now, although viewport rendering is broken and any
kind of network error or connection failure will kill Blender.
* Experimental WITH_CYCLES_NETWORK cmake option
* Networked Device is shown as an option next to CPU and GPU Compute
* Various updates to work with the latest Cycles code
* Locks and thread safety for RPC calls and tiles
* Refactored pointer mapping code
* Fix error in CPU brand string retrieval code
This includes work by Doug Gale, Martijn Berger and Brecht Van Lommel.

It was never fully implemented and will be replaced by OpenSubdiv. Only linear
subdivision remains now. Also includes some refactoring in the split/dice code,
adding a SubdParams struct to pass around parameters more easily.
* More build fixes, 2 link errors remain. http://www.pasteall.org/45279
Note: Probably those paths should only be added for Windows and Linux, as "OPENIMAGEIO_LIBPATH" already inherit them for Mac OS. Also "OPENIMAGEIO_LIBRARIES" inherits the libs for Linux already. Is that intended or a lack of consistency?
* Fix some link errors on Windows, still missing png, zlib, jpeg and tiff.
I couldn't yet figure out the correct flags to pass on here, and the 2300 lines huge main CMakeLists file doesn't help with it...
Regular rendering now works tiled, and supports save buffers to save memory
during render and cache render results.

I haven't had a chance to run those through Brecht, but would like to do eventually. (they work fine though)
For sample images see:
http://www.dalaifelinto.com/?p=399 (equisolid)
http://www.dalaifelinto.com/?p=389 (equidistant)
The 'use_panorama' option is now part of a new Camera type: 'Panorama'.
Created two other panorama cameras:
- Equisolid: most of lens in the market simulate this lens - e.g. Nikon, Canon, ...)
this works as a real lens up to an extent. The final result takes the
sensor dimensions into account also.
.:. to simulate a Nikon DX2S with a 10.5mm lens do:
sensor: 23.7 x 15.7
fisheye lens: 10.5
fisheye fov: 180
render dimensions: 4288 x 2848
- Equidistant: this is not a real lens model. Although the old equidistant lens simulate
this lens. The result is always as a circular fisheye that takes the whole sensor
(in other words, it doesn't take the sensor into consideration).
This is perfect for fulldomes ;)
For the UI we have 10 to 360 as soft values and 10 to 3600 as hard values (because we can).
Reference material:

Note, this is not a real simulation of the light path through the lens.
The ideal solution would be this:

Thanks Brecht for the fix, suggestions and code review.
Kudos for the dome community for keeping me stimulated on the topic since 2009 ;)
Patch partly implemented during lab time at VisGraf, IMPA - Rio de Janeiro.
Most of the changes are related to adding support for motion data throughout
the code. There's some code for actual camera/object motion blur raytracing
but it's unfinished (it badly slows down the raytracing kernel even when the
option is turned off), so that code it disabled still.
Motion vector export from Blender tries to avoid computing derived meshes
when the mesh does not have a deforming modifier, and it also won't store
motion vectors for every vertex if only the object or camera is moving.
environment map, by enabling the Panorama option in the camera.
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Camera#Panorama
The focal length or sensor settings are not used, the UI can be tweaked still to
communicate this, also panorama should probably become a proper camera type like
perspective or ortho.
Contrast helps to adjust IBL (HDR images used for background lighting).
Note: In the UI we are caling it Bright instead of Brightness. This copy what Blender composite is doing.
Note2: the algorithm we are using produces pure black when contrast is 100. I'm not a fan of that, but it's a division by zero. I would like to look at other algorithms (what gimp does for example). But that would be only after 2.62.
* Added some new integrator parameters to the xml reading.
* Added ability to specify window width/height, if not set it uses film/camera width/height.
* Added back the xml exporter script from cycles branch, with modifications to hock up into the UI. To use it, copy the script into 2.61/scripts/startup.
Note: This is intended for developers for now, but the standalone Cycles app has potential to be used as benchmark for example.
Node specially useful for Texture correction.
This is also a nice example of a simple node made from scratch in case someone wants to create their custom nodes.
Review by Brecht.
reviewed by Brecht, with help from Lukas.
Note: dot is reversed compared to Blender.
In Blender Normals point outside, while in Cycles they point inside.
If you use your own custom vector with the Normal Node you will see a difference.
If you feed it with object normals it should work just as good.
as with the HSV node the OSL code is relying on the (yet to be implemented) autorename.
Also the svm code could use mix (svm_lerp) instead:
32 . float3 color_inv = make_float3(1.0f, 1.0f, 1.0f) - color;
35 . . stack_store_float3(stack, out_color, svm_lerp(color_inv, color, factor));
I have a feeling that each node 'program' should have the least program as possible. I'll see with Brecht later.
But overall I don't know if that's any fast. And apart from that I think we will need this kind of function to move to a library if multiple functions linked in are not a problem.

Important note:
the camera Z is reverted compared to Blender render.
Now it goes from zero (camera) to positive (in front of the camera)
.........................
note, the OSL code has a problem.
In the original node the input and output nodes have the same name (Color).
So this will be fixed here once Brecht come up with a nice autorenaming (or we do a doversion patch) for that.
* Passes renamed to samples
* Camera lens radius renamed to aperature size/blades/rotation
* Glass and fresnel nodes input is now index of refraction
* Glossy and velvet fresnel socket removed
* Mix/add closure node renamed to mix/add shader node
* Blend weight node added for shader mixing weights
There is some version patching code for reading existing files, but it's not
perfect, so shaders may work a bit different.
* Add max diffuse/glossy/transmission bounces
* Add separate min/max for transparent depth
* Updated/added some presets that use these options
* Add ray visibility options for objects, to hide them from
camera/diffuse/glossy/transmission/shadow rays
* Is singular ray output for light path node
Details here:
http://wiki.blender.org/index.php/Dev:2.5/Source/Render/Cycles/LightPaths
* Add alpha pass output, to use set Transparent option in Film panel.
* Add Holdout closure (OSL terminology), this is like the Sky option in the
internal renderer, objects with this closure show the background / zero
alpha.
* Add option to use Gaussian instead of Box pixel filter in the UI.
* Remove camera response curves for now, they don't really belong here in
the pipeline, should be moved to compositor.
* Output full float values for rendering now, previously was only byte precision.
* Add a patch from Thomas to get a preview passes option, but still disabled
because it isn't quite working right yet.
* CUDA: don't compile shader graph evaluation inline.
* Convert tabs to spaces in python files.
* auto/fixed threads option is used now, patch by Thomas.
* remove unused CUDA_LIBRARIES, library is dynamically loaded
* fix mesh XML export operator for API update
* add some (disabled) test code for using OpenImageIO in imbuf
* link cycles, openimageio and boost into blender instead of a shared library
* some cmakefile changes to simplify the code and follow conventions better
* this may solve running cycles problems on windows XP, or give a different
and hopefully more useful error message
* kernel has shading nodes / textures disabled, amd/nvidia opencl
compilers choke on these, need to figure out how to avoid this
* works in cycles_test, not available as option in blender yet
* kernel compiles and runs with opencl 1.1 from intel/amd/nvidia
