This patch adds "Pixel Size" to the performance options, which allows to render
in a smaller resolution, which is especially useful for displays with high DPI.

We can't free the identifier before its used when
removing from the ghash.

Note that some little parts of code have been dissabled because eval_ctx
was not available there. This should be resolved once DerivedMesh is
replaced.

This commit contains the first part of the new Cycles denoising option,
which filters the resulting image using information gathered during rendering
to get rid of noise while preserving visual features as well as possible.
To use the option, enable it in the render layer options. The default settings
fit a wide range of scenes, but the user can tweak individual settings to
control the tradeoff between a noise-free image, image details, and calculation
time.
Note that the denoiser may still change in the future and that some features
are not implemented yet. The most important missing feature is animation
denoising, which uses information from multiple frames at once to produce a
flicker-free and smoother result. These features will be added in the future.
Finally, thanks to all the people who supported this project:
- Google (through the GSoC) and Theory Studios for sponsoring the development
- The authors of the papers I used for implementing the denoiser (more details
on them will be included in the technical docs)
- The other Cycles devs for feedback on the code, especially Sergey for
mentoring the GSoC project and Brecht for the code review!
- And of course the users who helped with testing, reported bugs and things
that could and/or should work better!

Previously, every RenderPass would have a bitfield that specified its type. That limits the number of passes to 32, which was reached a while ago.
However, most of the code already supported arbitrary RenderPasses since they were also used to store Multilayer EXR images.
Therefore, this commit completely removes the passflag from RenderPass and changes all code to use the unique pass name for identification.
Since Blender Internal relies on hardcoded passes and to preserve compatibility, 32 pass names are reserved for the old hardcoded passes.
To support these arbitrary passes, the Render Result compositor node now adds dynamic sockets. For compatibility, the old hardcoded sockets are always stored and just hidden when the corresponding pass isn't available.
To use these changes, the Render Engine API now includes a function that allows render engines to add arbitrary passes to the render result. To be able to add options for these passes, addons can now add their own properties to SceneRenderLayers.
To keep the compositor input node updated, render engine plugins have to implement a callback that registers all the passes that will be generated.
From a user perspective, nothing should change with this commit.

This is part of the new draw manager design. Any engine (even clay, eevee, ...) should be able to draw to the viewport, as well as render to an image directly.
Changing the API names to conform to that.

First this replace a custom data struct with IDProperty, and use
IDProperty group merge and copying functions. Which means that a collection
property setting is only created if necessary.
This implements the "Layer Collection settings" override system, as
suggested in the "Override Manifesto" document.
The core is working, with Scene, LayerCollection and Object using a
single IDProperty to store all the render settings data. Next step is to
migrate this to depsgraph.
Note: Clay engine "ssao_samples" was hardcoded to 32 for now. It will come
back as part of "Workspace Settings" later.
Many thanks for Bastien Montagne for the help with the UI template
nightmare ;)

Initial work by Clément Foucault with contributions from Dalai Felinto
(mainly per-collection engine settings logic, and depsgraph iterator placeholder).
This makes Blender require OpenGL 3.3. Which means Intel graphic card
and OSX will break. Disable CLAY_ENGINE in CMake in those cases.
This is a prototype render engine intended to help the design of real
render engines. This is mainly an engine with enphasis in matcap and
ambient occlusion.
Implemented Features
--------------------
* Clay Render Engine, following the new API, to be used as reference for
future engines
* A more complete Matcap customization with more options
* Per-Collection render engine settings
* New Ground Truth AO - not enabled
Missing Features
----------------
* Finish object edit mode
- Fix shaders to use new matrix
- Fix artifacts when edge does off screen
- Fix depth issue
- Selection sillhouette
- Mesh wires
- Use mesh normals (for higher quality matcap)
- Non-Mesh objects drawing
- Widget drawing
- Performance issues
* Finish mesh edit mode
- Derived-Mesh-less edit mode API (mesh_rende.c)
* General edit mode
- Per-collection edit mode settings
* General engines
- Per-collection engine settings
(they are their, but they still need to be flushed by depsgraph, and
used by the drawing code)

internal flags.
This gives us 9 flags available again for properties (we had none anymore),
and also makes things slightly cleaner.
To simplify (and make more clear the differences between mere properties
and function parameters), also added RNA_def_parameter_flags function (and
its clear counterpart), to be used instead of RNA_def_property_flag for
function parameters.
This patch is also a big cleanup (some RNA function definitions were
still using 'prop' PropertyRNA pointer, etc.).
And yes, am aware this will be annoying for all branches, but we really need
to get new flags available for properties (will need at least one for override, etc.).

This is a new option for panorama cameras to render
stereo that can be used in virtual reality devices
The option is available under the camera panel when Multi-View is enabled (Views option in the Render Layers panel)
Known limitations:
------------------
* Parallel convergence is not supported (you need to set a convergence distance really high to simulate this effect).
* Pivot was not supposed to affect the render but it does, this has to be looked at, but for now set it to CENTER
* Derivatives in perspective camera need to be pre-computed or we shuld get rid of kcam->dx/dy (Sergey words, I don't fully grasp the implication shere)
* This works in perspective mode and in panorama mode. However, for fully benefit from this effect in perspective mode you need to render a cube map. (there is an addon for this, developed separately, perhaps we could include it in master).
* We have no support for "neck distance" at the moment. This is supposed to help with objects at short distances.
* We have no support to rotate the "Up Axis" of the stereo plane. Meaning, we hardcode 0,0,1 as UP, and create the stereo pair related to that. (although we could take the camera local UP when rendering panoramas, this wouldn't work for perspective cameras.
* We have no support for interocular distance attenuation based on the proximity of the poles (which helps to reduce the pole rotation effect/artifact).
THIS NEEDS DOCS - both in 2.78 release log and the Blender manual.
Meanwhile you can read about it here: http://code.blender.org/2015/03/1451
This patch specifically dates from March 2015, as you can see in the code.blender.org post. Many thanks to all the reviewers, testers and minor sponsors who helped me maintain spherical-stereo for 1 year.
All that said, have fun with this. This feature was what got me started with Multi-View development (at the time what I was looking for was Fulldome stereo support, but the implementation is the same). In order to make this into Blender I had to make it aiming at a less-specic user-case Thus Multi-View started. (this was December 2012, during Siggraph Asia and a chat I had with Paul Bourke during the conference). I don't have the original patch anymore, but you can find a re-based version of it from March 2013, right before I start with the Multi-View project https://developer.blender.org/P332

The combined pass is built with the contributions the user finds fit.
It is useful for lightmap baking, as well as non-view dependent effects
baking.
The manual will be updated once we get closer to the 2.77 release.

ray intersection
TODO: We might want to refactor debug passes into PASS_DEBUG and some
debug_type (similar to Blender's side passes) to avoid issue of running
out of bits.
|
|
This way it is now possible to select which exact debug pass is to be used
by the render engine. Accessible from the Passes panel.
Currently it could only be one debug pass, in the future we can make menus
and image users smarter and support multiple passes of the same type.
|
|
Quite straightforward implementation, but still needs some work for the split
kernel. Includes both regular and split kernel implementation for that.
The pass is not exposed to the interface yet because it's currently not really
easy to have same pass listed in the menu multiple times.

Combine all the highpoly pixel arrays into a single array with a lookup
object_id for each of the highpoly objects.
Note: This changes the Bake API, external engines should refer to the
bake_api.c for the latest API.

This approach gets rid of iuser->pass for good.
Also, I'm commenting out the pass increase/decrease. This was broken
since multiview. I will fix it later (before 2.75), but I didn't want to
get this patch mangled with that fix.

Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.
Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.
Everything else is likely small todos, and may wait until we are sure none of the above is happening.
Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

Makes usage of those funcs much more clear, we even had mixed '!strcmp(foo, bar)'
and 'strcmp(foo, bar) == 0' in several places...

This function sets an error message which would be displayed after
rendering is over and info space lost the link to the engine.

Currently only summed number of traversal steps and intersections used by the
camera ray intersection pass is implemented, but in the future we will support
more debug passes which would help checking what things makes the scene slow.
Example of such extra passes could be number of bounces, time spent on the
shader tree evaluation and so.
Implementation from the Cycles side is pretty much straightforward, could only
mention here that it's a build-time option disabled by default.
From the blender side it's implemented as a PASS_DEBUG with several subtypes
possible. This way we don't need to create an extra DNA pass type for each of
the debug passes, saving us a bits.

New operator that can calls a bake function to the current render engine when available. This commit provides no feature for the users, but allows external engines to be accessed by the operator and be integrated with the baking api.
The API itself is simple. Blender sends a populated array of BakePixels to the renderer, and gets back an array of floats with the result.
The Blender Internal (and multires) system is still running independent, but we eventually will pipe it through the API as well. Cycles baking will come next as a separated commit
Python Operator:
----------------
The operator can be called with some arguments, or a user interface can be created for it. In that case the arguments can be ommited and the interface can expose the settings from bpy.context.scene.render.bake
bpy.ops.object.bake(type='COMBINED', filepath="", width=512, height=512, margin=16, use_selected_to_active=False, cage_extrusion=0, cage="", normal_space='TANGENT', normal_r='POS_X', normal_g='POS_Y', normal_b='POS_Z', save_mode='INTERNAL', use_clear=False, use_split_materials=False, use_automatic_name=False)
Note: external save mode is currently disabled.
Supported Features:
------------------
* Margin - Baked result is extended this many pixels beyond the border of each UV "island," to soften seams in the texture.
* Selected to Active - bake shading on the surface of selected object to the active object. The rays are cast from the lowpoly object inwards towards the highpoly object. If the highpoly object is not entirely involved by the lowpoly object, you can tweak the rays start point with Cage Extrusion. For even more control of the cage you can use a Cage object.
* Cage Extrusion - distance to use for the inward ray cast when using selected to active
* Custom Cage - object to use as cage (instead of the lowpoly object).
* Normal swizzle - change the axis that gets mapped to RGB
* Normal space - save as tangent or object normal spaces
Supported Passes:
-----------------
Any pass that is supported by Blender renderlayer system. Though it's up to the external engine to provide a valid enum with its supported passes. Normal passes get a special treatment since we post-process them to converted and "swizzled"
Development Notes for External Engines:
---------------------------------------
(read them in bake_api.c)
* For a complete implementation example look at the Cycles Bake commit (next).
