Cycles OSL: shader script node Documentation here: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/OSL http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.65/Cycles These changes require an OSL build from this repository: https://github.com/DingTo/OpenShadingLanguage The lib/ OSL has not been updated yet, so you might want to keep OSL disabled until that is done. Still todo: * Auto update for external .osl files not working currently, press update manually * Node could indicate better when a refresh is needed * Attributes like UV or generated coordinates may be missing when requested from an OSL shader, need a way to request them to be loaded by cycles * Expose string, enum and other non-socket parameters * Scons build support Thanks to Thomas, Lukas and Dalai for the implementation.

CCL_NAMESPACE_BEGIN
Merge of the PyNodes branch (aka "custom nodes") into trunk. PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements. === Dynamic node type registration === Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes. Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2]. === Node group improvements === Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

Cycles: add location/rotate/scale and XYZ mapping options for all texture nodes, to reduce the amount of nodes needed to set up a simple texture. These are currently editable in the texture properties tab, still need to make them available in the node editor. Projection and color modification options will be added later, they're not implemented yet but allocated already to avoid version patches later. Also an issue with the XYZ mapping is that when you set one to None, texture and material draw mode doesn't draw the image texture well, OpenGL doesn't seem to like the degenerate texture matrix?

Still todo: * Auto update for external .osl files not working currently, press update manually * Node could indicate better when a refresh is needed * Attributes like UV or generated coordinates may be missing when requested from an OSL shader, need a way to request them to be loaded by cycles * Expose string, enum and other non-socket parameters * Scons build support Thanks to Thomas, Lukas and Dalai for the implementation.

Merge of the PyNodes branch (aka "custom nodes") into trunk. PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements. === Dynamic node type registration === Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes. Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2]. === Node group improvements === Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

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.

It gives better quality results in many ways, with the availability of both Cubic and Gaussian falloff functions, but also tends to be more noisy when using the progressive integrator and does not give great results with some geometry. It works quite well for the non-progressive integrator and is often less noisy there.

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).

Documentation has been updated with the latest changes: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes Patch by Agustin Benavidez, some implementation tweaks by me.

Example render: http://www.pasteall.org/pic/show.php?id=53202 ToDo: * Move some functions into an util file, maybe a common util_color.h or so. * Test GPU, unfortunately sm_21 doesn't work for me yet.

Cycles / Blackbody to RGB node: * Added a node to convert a temperature in Kelvin to an RGB color. This can be used e.g. for lights, to easily find the right color temperature. = Some common temperatures = Candle light: 1500 Kelvin Sunset/Sunrise: 1850 Kelvin Studio lamps: 3200 Kelvin Horizon daylight: 5000 Kelvin Documentation: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Blackbody Thanks to Philipp Oeser (lichtwerk), who essentially contributed to this with a patch! :) This is part of my GSoC 2013 project.

This enables addons such as render engines to create a complete user interface with nodes. Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2]. === Node group improvements === Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

Packed and generated images support for Cycles This commit adds support of packed and generated images for Cycles when using SVM backend. Movies are still not supported. This changes also doesn't touch OSL which is much less trivial to adopt for any images which are not saved to disk. Implementation details: - When adding images to Image Manager is now possible to mark image as builtin. Builtin images will bypass OIIO loader and will use special loading callbacks. - Callbacks are set by Blender Session and they're using C++ RNA interface to obtain needed data (pixels, dimensions, is_float flag). - Image Manager assumes file path is used as reference to a builtin images, but in fact currently image datablock name is used for reference. This makes it easy to find an image in BlendData database. - Added some extra properties to Image RNA: * channels, which denotes actual number of channels in ImBuf. This is needed to treat image's pixels correct (before it wasn't possible because API used internal number of channels for pixels which is in fact doesn't correlate with image depth) * is_float, which is truth if image is stored in float buffer of ImBuf. - Implemented string lookup for C++ RNA collections for cases there's no manual lookup function. OSL is not supported because it used own image loading and filtering routines and there's seems to be no API to feed pre-loaded pixels directly to the library. Think we'll either need to add some API to support such kind of feeding or consider OSL does not have support of packed images at all. Movies are not supported at this moment because of lack of RNA API to load specified frame. It's not difficult to solve, just need to consider what to best here: * Either write some general python interface for ImBuf and use it via C++ API, or * Write a PY API function which will return pixels for given frame, or * Use bad-level BKE_* call Anyway, small steps, further improvements later.

Merge of the PyNodes branch (aka "custom nodes") into trunk. PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements. === Dynamic node type registration === Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes. Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2]. === Node group improvements === Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout.

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

Add support for multiple interpolation modes on cycles image textures All textures are sampled bi-linear currently with the exception of OSL there texture sampling is fixed and set to smart bi-cubic. This patch adds user control to this setting. Added: - bits to DNA / RNA in the form of an enum for supporting multiple interpolations types - changes to the image texture node drawing code ( add enum) - to ImageManager (this needs to know to allocate second texture when interpolation type is different) - to node compiler (pass on interpolation type) - to device tex_alloc this also needs to get the concept of multiple interpolation types - implementation for doing non interpolated lookup for cuda and cpu - implementation where we pass this along to osl ( this makes OSL also do linear untill I add smartcubic to the interface / DNA/ RNA) Reviewers: brecht, dingto Reviewed By: brecht CC: dingto, venomgfx Differential Revision: https://developer.blender.org/D317

Fix #37194, OSL script crashes blender. The lookup functions for finding Cycles shader inputs/outputs based on socket names are using a few modifications on the Blender socket names. But these only apply to standard nodes where the Blender socket names can differ from associated Cycles names and may require additional indices to make them unique. Script node sockets are already unique and exact due to being generated from the script function parameters.

Merge of the PyNodes branch (aka "custom nodes") into trunk. PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements. === Dynamic node type registration === Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes. Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2]. === Node group improvements === Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

Fix #34948, bug in Cycles node groups. The proxy node maps used to identify external connections of node group nodes were having name clashes with input/output sockets of the same name, leading to invalid cyclic connections in the cycles shader graph that were subsequently removed (prints warnings in terminal). Solution is to use two separate maps for inputs and outputs so group node sockets can safely use the same identifier.

Merge of the PyNodes branch (aka "custom nodes") into trunk. PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements. === Dynamic node type registration === Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes. Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2]. === Node group improvements === Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel.

Custom Group Node type for extending existing nodes from python scripts. This is a sort of workaround for the lack of APIs in our existing node systems (compositor, cycles, BI, textures). These systems don't have any way to deal with scripted node types yet, which could in principle by added with pynodes. The NodeCustomGroup type adds a way of scripting nodes by automating node groups which the hardcoded system can then interpret like regular groups. The new NodeCustomGroup type has the basic node_tree pointer property like the regular group node types and also uses the same socket interface system as regular groups. This means that input/output sockets can be mapped to internal nodes in the same way as regular node groups in renderers and the compositor. On top of that, however, the NodeCustomGroup type can be subclassed in python scripts to flesh out scripted node types with own draw functions, properties, updates and so on. NB: Only cycles currently supports this node type and its derivatives, other systems may follow later.

Fix for #34708 and #34709, cycles group nodes were not working well with 0 or 2+ group input/output nodes. The issue here was that the proxy nodes created for connecting extern group node sockets to the internal nodes were generated by the input/output nodes themselves. 0 input/output nodes: there would be no proxy that external group node sockets can map to 2+ input/output nodes: additional nodes would overwrite entries from previous nodes, so that only one of the input/output nodes would be used. Solution is to always generate exactly 1 proxy node for every group socket in advance, regardless of whether it is used internally. Internal node sockets can then all map to this proxy node. In the case out output nodes there should only ever be one active node, otherwise the connection to the proxy would be ambiguous. For this purpose the NODE_DO_OUTPUT flag has been exposed to RNA, so that cycles can check it and only use the active output.

*/
Generalized node groups for Cycles. This allows group nodes inside other group nodes in cycles and makes the code more generic for all possible cases, like direct group input-to-output links and unused group sockets. Previous code tried to connect external nodes and internal group sockets by following links until a "real" node input/output. This quickly becomes complicated in corner cases as described above and can lead to unexpected behavior when the group socket is of a different type than the internal/external sockets, but that conversion is skipped. The new code uses the concept of "proxy nodes" similar to what the new compositor does. Each group socket is replaced with a proxy node with a single input and output, to which other nodes in the same tree and internal nodes can link to. After all groups have been expanded in the graph, these proxy nodes are removed again, adding converter nodes if necessary.

For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel.

Fix #34948, bug in Cycles node groups. The proxy node maps used to identify external connections of node group nodes were having name clashes with input/output sockets of the same name, leading to invalid cyclic connections in the cycles shader graph that were subsequently removed (prints warnings in terminal). Solution is to use two separate maps for inputs and outputs so group node sockets can safely use the same identifier.

Generalized node groups for Cycles. This allows group nodes inside other group nodes in cycles and makes the code more generic for all possible cases, like direct group input-to-output links and unused group sockets. Previous code tried to connect external nodes and internal group sockets by following links until a "real" node input/output. This quickly becomes complicated in corner cases as described above and can lead to unexpected behavior when the group socket is of a different type than the internal/external sockets, but that conversion is skipped. The new code uses the concept of "proxy nodes" similar to what the new compositor does. Each group socket is replaced with a proxy node with a single input and output, to which other nodes in the same tree and internal nodes can link to. After all groups have been expanded in the graph, these proxy nodes are removed again, adding converter nodes if necessary.

* because the node type is not supported */
Merge of the PyNodes branch (aka "custom nodes") into trunk. PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements. === Dynamic node type registration === Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes. Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2]. === Node group improvements === Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

Fix #34948, bug in Cycles node groups. The proxy node maps used to identify external connections of node group nodes were having name clashes with input/output sockets of the same name, leading to invalid cyclic connections in the cycles shader graph that were subsequently removed (prints warnings in terminal). Solution is to use two separate maps for inputs and outputs so group node sockets can safely use the same identifier.

Cycles Volume Render: heterogeneous (textured) volumes support. Volumes can now have textured colors and density. There is a Volume Sampling panel in the Render properties with these settings: * Step size: distance between volume shader samples when rendering the volume. Lower values give more accurate and detailed results but also increased render time. * Max steps: maximum number of steps through the volume before giving up, to protect from extremely long render times with big objects or small step sizes. This is much more compute intensive than homogeneous volume, so when you are not using a texture you should enable the Homogeneous Volume option in the material or world for faster rendering. One important missing feature is that Generated texture coordinates are not yet working in volumes, and they are the default coordinates for nearly all texture nodes. So until that works you need to plug in object texture coordinates or a world space position. This is work by "storm", Stuart Broadfoot, Thomas Dinges and myself.

shader->heterogeneous_volume = !get_boolean(cmat, "homogeneous_volume");
Cycles: volume sampling method can now be set per material/world. This gives you "Multiple Importance", "Distance" and "Equiangular" choices. What multiple importance sampling does is make things more robust to certain types of noise at the cost of a bit more noise in cases where the individual strategies are always better. So if you've got a pretty dense volume that's lit from far away then distance sampling is usually more efficient. If you've got a light inside or near the volume then equiangular sampling is better. If you have a combination of both, then the multiple importance sampling will be better.

BL::ShaderNodeTree b_ntree(b_lamp->node_tree());
Fix #34948, bug in Cycles node groups. The proxy node maps used to identify external connections of node group nodes were having name clashes with input/output sockets of the same name, leading to invalid cyclic connections in the cycles shader graph that were subsequently removed (prints warnings in terminal). Solution is to use two separate maps for inputs and outputs so group node sockets can safely use the same identifier.
