9d2173518c Clipboard feature for nodes. With the Copy operator a copy of all selected nodes and links between them is stored in an offscreen list (not in the library). The Paste operator then in turn copies these into the active node tree in the editor.
Currently does not support copying of animation data. This would require copying of individual fcurves etc. between data block, which is not implemented yet.

Also it is currently possible to circumvent some constraints of the nodes, in particular for node groups (e.g. no groups inside groups, render layer not inside groups).

1f19bacf8e Kaying node from tomato branch
Merge keying node from tomato branch into trunk.

It was considered stable and helpful by Mango team and it'll help
studio pipeline, because nodes would stop disappearing when opening
files in current trunk.

d56e77ada5 Keying Screen node from tomato branch
Merge Keying Screen node developed in tomato branch into trunk.

This node is aimed to make dealing with non-even greenscreens better
by generating gradiented image which could be used a input for keyer
nodes.

Based on building voronoi diagram using motion tracking markers as
sites position and average pattern color as color for that site.

Pretty straignforward node, some documentation is there

6c4510f681 Modification of node groups by adding/removing nodes is not possible yet. This patch extends the 'Make Group' operator and adds a new 'Separate' operator to add such functionality.
1) For inserting into existing groups:
  The 'Make Group from selected' (CTRL+g) operator shows a selection popup (like the object parenting operator), with options depending on the type of the active node (last selected):
  * "New" -> regular operator, creates new group type with all selected nodes inside.
  * "Insert" (only if active node is a group) -> adds all other selected nodes into the group.

  Currently still prohibits groups inside groups in general, though would be technically possible as long as no actual recursion occurs (group containing itself).

2) For extracting from an existing group:
  New 'Separate from group' operator (p), works similar to separating vertices/edges/faces from mesh. Two modes:
  * "Copy" makes a copy of the nodes in the parent tree, but keeps the original group intact.
  * "Move" removes selected nodes from the node group and adds them to the parent tree

5e1bbde01d Particle Info node for Cycles. This can be used to access particle information in material shaders for dupli objects. For now only the particle Age and individual Lifetime (in frames) are supported, more attributes can be added when needed.
The particle data is stored in a separate texture if any of the dupli objects uses particle info nodes in shaders. To map dupli objects onto particles the store an additional particle_index value, which is different from the simple dupli object index (only visible particles, also works for particle dupli groups mode).

Some simple use cases on the code.blender.org blog:

17935168c0 Reroute nodes, by Jeroen Bakker (patch #28443).
By holding shift and "cutting" a node link a new reroute helper node can be inserted. This consists of a single socket that can be used to insert additional connection points into a link. This can be used to keep a connection point in the tree when  deleting a node, or to control the path of long connections for layout cleanup.

876665ac25 Initial commit of new keying nodes
First node is called Keying Screen (Add -> Matte -> Keying Screen) and it's
aimed to resolve issues with gradients on green screens by producing image
with gradient which is later used as an input for screen color in keying nodes.

This node gets motion tracks from given movie clip and trackign object and uses
them to define color and position of points of gradient: for position marker's
position on current frame is sued, for color average color of pattern area is
used.

Gradient is calculating in the following way:
- On first step voronoi diagram is creating for given tracks.
- On second step triangulation of this diagram happens by connecting sites
  to edges which defines area this site belongs to.
- On third step gradient filling of this triangles happens. One of triangle
  vertices is colored with average track color, two rest vertoces are colored
  with average color between two neighbor sites. Current pixel's color in
  triangle is calculating as linear combination of vertices colors and
  barycentric coordinates of this pixel.

This node is implemented for both tile and legacy compositor systems.

Second node is basically a combination of several existing nodes to make keying
more straighforward and reduce spagetti mess in the compositor, but it also
ships some fresh approaches calculating matte which seems to be working better
for not actually green screens.

This node supports:
- Chroma preblur
- Dispilling
- Clip white/black
- Dilate/Erode
- Matte post blur

This node doesn't support chroma pre-blur for legacy compositor (yet).

There're still lots of stuff to be improved here, but this nodes night already
be used i think.

Some details might be found on this wiki page:
http://wiki.blender.org/index.php/User:Nazg-gul/Keying

This patch also contains some currently unused code from color math module, but
it was used for tests and might be used for tests in the future. Think it's ok
to have it in branch at least.

53b01d9002 A number of new features for the node editor in general and the Frame node in particular.
For an detailed user-level description of new features see the following blogpost:

http://code.blender.org/index.php/2012/05/node-editing-tweaks/

TL;DR:
* Frame node gets more usable bounding-box behavior
* Node resizing has helpful mouse cursor indicators and works on all borders
* Node selection/active colors are themeable independently
* Customizable background colors for nodes (useful for frames visual
distinction).

c3e1fce775 Cycles: add Object Info node, with outputs object location, object/material
pass index, and a random number unique to the instance of the object.

This can be useful to give some variation to a single material assigned to

9d91bc38d3 A couple more changes to the file and image nodes to improve access to layers that don't follow Blender's rlayer.rpass naming scheme.
--- Changes to File Output node ---
* Flat layer names in EXR multilayer files.

 For a socket with name "AAA" the previous resulting EXR layer name would be "AAA.AAA", i.e. the render layer as well as render pass would use the socket name.

 Now the "render_layer.render_pass" scheme is ignored in multilayer files, socket names are directly written to EXR layers (EXR layer name is "AAA" in this example). If sockets should have a notion of "render layer" this can still be achieved by explicitly adding a separator, e.g. "AAA.BBB". When loading such layers into a Blender Image struct, the name is interpreted as a "render_layer.render_pass" again (although the image node does not care about it, see below).

* Socket sub-paths (for singlelayer) or layer names (for multilayer) are stored in dedicated string variables in the socket storage data. This way the RNA can define precise string subtypes (PROP_FILEPATH) and length. The file/layer slots are defined as separate structs with own name properties in the RNA as well, so they can be used nicely with the list template.

* Ensure unique socket paths/layer names to prevent overwriting of files and layers respectively.

--- Changes to Image node ---
* Loading multilayer OpenEXR files has improved layer name splitting into render layer + render pass names now. This properly supports arbitrary EXR layer names now.
  Example:

 OpenEXR layer name:   AAA.BBB.CCC

 is split into

 Render layer name:    AAA.BBB
 Render pass name:     CCC

 If the layer name has no '.' separators the render layer name is empty.

* Image node ignores the selected render layer in the image user data. Instead all existing layers are displayed at the same time by combining the render layer names with render pass names again, to reconstruct the original EXR layer name. This avoids the problem that render layers with empty name are not selectetable in the dropdown and allows using all image layers at the same time without duplicating the node.

01b3deb680 A number of changes to node RNA and the file output node, to simplify socket types and make node code more robust for future nodes with extra socket data.
* Removed the struct_type identifier from sockets completely. Any specialization of socket types can be done by using separate collections in RNA and customized socket draw callbacks in node type. Sockets themselves are pure data inputs/outputs now. Possibly the sock->storage data could also be removed, but this will change anyway with id properties in custom nodes.

* Replaced the direct socket button draw calls by extra callbacks in node types. This allows nodes to draw sockets in specialized ways without referring to the additional struct_type identifier. Default is simply drawing the socket default_value button, only file output node overrides this atm.

* File output node slots now use a separate file sub-path in their storage data, instead of using the socket name. That way the path is an actual PROP_FILEPATH property and it works better with the UI list template (name property is local to the data struct).

* Node draw contexts for options on the node itself and detail buttons in the sidebar now have an extra context pointer "node" (uiLayoutSetContextPointer). This can be used to bind operator buttons to a specific node, instead of having to rely on the active/selected node(s) or making weak links via node name. Compare to modifiers and logic bricks, they use the same feature.

* Added another operator for reordering custom input slots in the file output node.

9151d46d7d Tomato: initial commit of mask editing tools into SVN
- Added new dtaablock called Mask which might be re-used in any area.
  Currently editing of masks happens in clip editor and they might be used in
  compositor nodes only.
- Added new mode to clip clip editor to interact with masks.
  Implemented basic tools to create shapes, splines and points. Also implemented
  idea of UW points for feather which means feather points are have got U
  coordinate along spline (which is measured from 0 to 1) and W is it's weight
  meaning distance from main spline.
- Spline points might be parented to movie tracks.
  Interface for this isn't best yet.
- Rasterisaztion of masks happens in compositor node (Input -> Mask)
  Input image of this ode is used as reference for mask resolution.
  Currently all splines of all shapes are rasterizing independently which
  means shapes with holes are not supported.
  Also feather rasterization is not implemented.

  Rasterized was implemented by Pete Larbell, thanks!

Do not consider this is something finished, there's still lots of things to
be done (especially from interface and usability points of view).

2eb29e4788 A number of improvements for the file output node(s).
1) Old CMP_NODE_OUTPUT_FILE and CMP_NODE_OUTPUT_MULTI_FILE have been merged,
only CMP_NODE_OUTPUT_FILE remains. All functions renamed accordingly.

2) do_versions code for converting single-file output nodes into multi-file
output nodes. If a Z buffer input is used, the node is made into a multilayer
exr with two inputs. (see below). Also re-identifies multi-file output nodes
with the CMP_NODE_OUTPUT_FILE type.

3) "Global" format is stored in node now. By default this overrides any
per-socket settings.

4) Multilayer EXR output implemented. When M.EXR format is selected for node
format, all socket format details are ignored. Socket names are used for layer
names.

5) Input buffer types are used as-is when possible, i.e. stored as B/W, RGB or
RGBA. In regular file output the format dictates the number of actual channels,
so the CompBuf is typechecked to the right type first. For multilayer EXR the
number of channels is more flexible, so an input buffer will store only the
channels it actually uses.

6) The editor socket type is updated from linked sockets as an indicator of the
actual data written to files. This may not be totally accurate for regular file
output though, due to restrictions of format setting.

050428049f Implements a new operator for detaching nodes. In the process i overhauled the node muting system as well.
There are a number of features that use a kind of "internal linking" in nodes:
1. muting
2. delete + reconnect (restore link to/from node after delete)
3. the new detach operator (same as 2, but don't delete the node)

The desired behavior in all cases is the same: find a sensible mapping of inputs-to-outputs of a node. In the case of muting these links are displayed in red on the node itself. For the other operators they are used to relink connections, such that one gets the best possible ongoing link between previous up- and downstream nodes.

Muting previously used a complicated callback system to ensure consistent behavior in the editor as well as execution in compositor, shader cpu/gpu and texture nodes. This has been greatly simplified by moving the muting step into the node tree localization functions. Any muted node is now bypassed using the generalized nodeInternalRelink function and then removed from the local tree. This way the internal execution system doesn't have to deal with muted nodes at all, as if they are non-existent.

The same function is also used by the delete_reconnect and the new links_detach operators (which work directly in the editor node tree). Detaching nodes is currently keymapped as a translation variant (macro operator): pressing ALTKEY + moving node first detaches and then continues with regular transform operator. The default key is ALT+DKEY though, instead ALT+GKEY, since the latter is already used for the ungroup operator.

3bae60d0c9 Adds a new node type for saving multiple image files from a single node.
Unlike the existing file output node this node has an arbitrary number of
possible input slots. It has a base path string that can be set to a general
base folder. Every input socket then uses its name as an extension of the base
path for file organization. This can include further subfolders on top of the
base path. Example:

Base path: '/home/user/myproject'
Input 1: 'Compo'
Input 2: 'Diffuse/'
Input 3: 'details/Normals'

would create output files
in /home/user/myproject: Compo0001.png, Compo0002.png, ...
in /home/user/myproject/Diffuse: 0001.png, 0002.png, ... (no filename base
given)
in /home/user/myproject/details: Normals0001.png, Normals0002.png, ...

Most settings for the node can be found in the sidebar (NKEY). New input sockets
can be added with the "Add Input" button. There is a list of input sockets and
below that the details for each socket can be changed, including the sub-path
and filename. Sockets can be removed here as well. By default each socket uses
the render settings file output format, but each can use its own format if
necessary.

To my knowledge this is the first node making use of such dynamic sockets in
trunk. So this is also a design test, other nodes might use this in the future.

Adding operator buttons on top of a node is a bit unwieldy atm, because all node
operators generally work on selected and/or active node(s). The operator button
would therefore either have to make sure the node is  activated before the
operator is called (block callback maybe?) OR it has to store the node name
(risky, weak reference). For now it is only used in the sidebar, where only the
active node's buttons are displayed.

Also adds a new struct_type value to bNodeSocket, in order to distinguish
different socket types with the same data type (file inputs are SOCK_RGBA color
sockets). Would be nicer to use data type only for actual data evaluation, but
used in too many places, this works ok for now.

335ffb0ff3 Brightness/Contrast Node for Cycles
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.
