799779d432 Cycles: change Ambient Occlusion shader to output colors.
This means the shader can now be used for procedural texturing. New
settings on the node are Samples, Inside, Local Only and Distance.

Original patch by Lukas with further changes by Brecht.

48155c210a Cycles: Add Support for IES files as textures for light strength
This patch adds support for IES files, a file format that is commonly used to store the directional intensity distribution of light sources.
The new IES node is supposed to be plugged into the Strength input of the Emission node of the lamp.

Since people generating IES files do not really seem to care about the standard, the parser is flexible enough to accept all test files I have tried.
Some common weirdnesses are distributing values over multiple lines that should go into one line, using commas instead of spaces as delimiters and adding various useless stuff at the end of the file.

The user interface of the node is similar to the script node, the user can either select an internal Text or load a file.
Internally, IES files are handled similar to Image textures: They are stored in slots by the LightManager and each unique IES is assigned to one slot.

The local coordinate system of the lamp is used, so that the direction of the light can be changed. For UI reasons, it's usually best to add an area light,
rotate it and then change its type, since especially the point light does not immediately show its local coordinate system in the viewport.

f1a5fd90ba Shader Node Editor: Add Closure to RGB convertion node.
Patch D3205 by Kanzaki Wataru

Only implemented in Eevee for now. Collapse a closure to RGBA so we can
do NPR stuff on the resulting color.

Use an emission shader to convert the color back to a closure.

Doing this will break PBR and will kill any SSR and SSS effects the shader
the shader rely on. That said screen space refraction and ambient occlusion
are supported due to the way they are implemented.

51b796ff15 Remove Blender Internal and legacy viewport from Blender 2.8.
Brecht authored this commit, but he gave me the honours to actually
do it. Here it goes; Blender Internal. Bye bye, you did great!

* Point density, voxel data, ocean, environment map textures were removed,
  as these only worked within BI rendering. Note that the ocean modifier
  and the Cycles point density shader node continue to work.
* Dynamic paint using material shading was removed, as this only worked
  with BI. If we ever wanted to support this again probably it should go
  through the baking API.
* GPU shader export through the Python API was removed. This only worked
  for the old BI GLSL shaders, which no longer exists. Doing something
  similar for Eevee would be significantly more complicated because it
  uses a lot of multiplass rendering and logic outside the shader, it's
  probably impractical.
* Collada material import / export code is mostly gone, as it only worked
  for BI materials. We need to add Cycles / Eevee material support at some
  point.
* The mesh noise operator was removed since it only worked with BI
  material texture slots. A displacement modifier can be used instead.
* The delete texture paint slot operator was removed since it only worked
  for BI material texture slots. Could be added back with node support.

* Not all legacy viewport features are supported in the new viewport, but
  their code was removed. If we need to bring anything back we can look at
  older git revisions.
* There is some legacy viewport code that I could not remove yet, and some
  that I probably missed.
* Shader node execution code was left mostly intact, even though it is not
  used anywhere now. We may eventually use this to replace the texture
  nodes with Cycles / Eevee shader nodes.

* The Cycles Bake panel now includes settings for baking multires normal
  and displacement maps. The underlying code needs to be merged properly,
  and we plan to add back support for multires AO baking and add support
  to Cycles baking for features like vertex color, displacement, and other
  missing baking features.

* This commit removes DNA and the Python API for BI material, lamp, world
  and scene settings. This breaks a lot of addons.
* There is more DNA that can be removed or renamed, where Cycles or Eevee
  are reusing some old BI properties but the names are not really correct
  anymore.
* Texture slots for materials, lamps and world were removed. They remain
  for brushes, particles and freestyle linestyles.
* 'BLENDER_RENDER' remains in the COMPAT_ENGINES of UI panels. Cycles and
  other renderers use this to find all panels to show, minus a few panels
  that they have their own replacement for.

f9cf2e2f6c Workspaces: remove workspace engine, use 3D viewport draw mode instead.
ViewRender was removed, which means we can't get the render engine for files
saved in 2.8. We assume that any files saved in 2.8 were intended to use Eevee
and set the engine to that.

A fix included with this is that .blend thumbails now draw with Clay mode,
and never Eevee or Cycles. These were drawn with solid mode in 2.7, and should
be very fast and not e.g. load heavy image textures.

0aec2dcd3a Cycles: add Principled Volume shader.
Similar to the Principled BSDF, this should make it easier to set up volume
materials. Smoke and fire can be rendererd with just a single principled
volume node, the appropriate attributes will be used when available. The node
also works for simpler homogeneous volumes like water or mist.

This adds midlevel and object/world space for displacement, and a
vector displacement node with tangent/object/world space, midlevel
and scale.

Note that tangent space vector displacement still is not exactly
compatible with maps created by other software, this will require
changes to the tangent computation.

f8b1430566 Eevee: Initial Separable Subsurface Scattering implementation.
How to use:
- Enable subsurface scattering in the render options.
- Add Subsurface BSDF to your shader.
- Check "Screen Space Subsurface Scattering" in the material panel options.

This initial implementation has a few limitations:
- only supports gaussian SSS.
- Does not support principled shader.
- The radius parameters is baked down to a number of samples and then put into an UBO. This means the radius input socket cannot be used. You need to tweak the default vector directly.
- The "texture blur" is considered as always set to 1

26f39e6359 Cycles: add bevel shader, for raytrace based rounded edges.
The algorithm averages normals from nearby surfaces. It uses the same
sampling strategy as BSSRDFs, casting rays along the normal and two
orthogonal axes, and combining the samples with MIS.

The main concern here is that we are introducing raytracing inside
shader evaluation, which could be quite bad for GPU performance and
stack memory usage. In practice it doesn't seem so bad though.

Note that using this feature can easily slow down renders 20%, and
that if you care about performance then it's better to use a bevel
modifier. Mainly this is useful for baking, and for cases where the
mesh topology makes it difficult for the bevel modifier to work well.

e4f2b2be26 Workspace: Move engines to workspace and Properties Editor cleanup
Engine is not stored in WorkSpaces. That defines the "context" engine, which
is used for the entire UI.

The engine used for the poll of nodes (add node menu, new nodes when "Use Nodes")
is obtained from context.

Introduce a ViewRender struct for viewport settings that are defined for
workspaces and scene. This struct will be populated with the hand-picked
settings that can be defined per workspace as per the 2.8 design.

* use_scene_settings
* properties editor: workshop + organize context path

Use Scene Settings
==================
For viewport drawing, Workspaces have an option to use the Scene render
settings (F12) instead of the viewport settings.

This way users can quickly preview the final render settings, engine and
View Layer. This will affect all the editors in that workspace, and it will be
clearly indicated in the top-bar.

Properties Editor: Add Workspace and organize context path
==========================================================

We now have the properties of:

Scene, Scene > Layer, Scene > World, Workspace

[Scene | Workspace] > Render Layer > Object
[Scene | Workspace] > Render Layer > Object > Data

resolved by connecting the shader output to a new output node.

Date:   Fri Sep 16 08:47:56 2016 +0200

    Fixed a bug in the Disney BSDF that caused specular reflections to be too
    bright and diffuse is now reacting to the roughness again

    - A normalization for the fresnel was missing which caused the specular
      reflections to become too bright for the single-scatter GGX
    - The roughness value for the diffuse BSSRDF part has always been
      overwritten and thus always 0
    - Also the performance for refractive materials with roughness=0.0 has
      been improved

    Added selection field to the Disney BSDF node for switching between
    "Multiscatter GGX" and "GGX"

    In the "GGX" mode there is an additional parameter for changing the
    refraction roughness for materials with smooth surfaces and rough interns
    (e.g. honey). With the "Multiscatter GGX" this effect can't be produced at
    the moment and so here will be no separation of the two roughness values.

    Attempt to fix Disney SSS

commit dbad91ca6d
Author: Pascal Schoen <pascal_schoen@gmx.net>
Date:   Wed Jul 20 11:13:00 2016 +0200

    Added a roughness parameter for refractions (for scattering of the rays
    within an object)

    With this, one can create a translucent material with a smooth surface and
    with a milky look.

    The final refraction roughness has to be calculated using the surface
    roughness and the refraction roughness because those two are correlated
    for refractions. If a ray hits a rough surface of a translucent material,
    it is scattered while entering the surface. Then it is scattered further
    within the object. The calculation I'm using is the following:

    RefrRoughnessFinal = 1.0 - (1.0 - Roughness) * (1.0 - RefrRoughness)

5abae51a6e Support multiple tangents for BI render & viewport
Normal Map node support for GLSL mode and the internal render (multiple tangents support).

The Normal Map node is a useful node which is present in the Cycles render.
It makes it possible to use normal mapping without additional material node in a node tree.
This patch implements Normal Map node for GLSL mode and the internal render.

Previously only the active UV layer was used to calculate tangents.

9b40616249 Cycles: Point density texture support
This commit implements point density texture for Cycles shading nodes.

It's done via creating voxel texture at shader compilation time, Not
totally memory efficient, but avoids adding sampling code to kernel
(which keeps render time as low as possible), In the future this will
be compensated by using OpenVDB for more efficient storage of sparse
volume data.

Sampling of the voxel texture is happening at blender side and the
same code is used as for Blender Internal's renderer.

This texture is controlled by only object, particle system and radius.
Linear falloff is used and there's no turbulence. This is because
falloff is expected to happen using Curve Mapping node. Turbulence
will be done as a distortion on the input coordinate. It's already
possible to fake it using nose textures and in the future we can add
more proper turbulence distortion node, which then could also be used
for 2D texture mapping.

Particle color support is done by Lukas, thanks!

a80c1e50bc Fix T44822: python enums' itemf callback did not handle 'NULL' context case.
Enum's itemf callback can be called without context in some cases (UI, doc generation...).
Python's enum properties did not handle this at all - it's kind of odd this did not cause
more trouble and wasn't notice earlier... Probably dynamic enums using context are not
much used in py code.

Note about nodes: those are heavy users of dynamic enum with context. Now,
we expect `NodeCategory.poll()` and `NodeItem.poll()` to always be called with
a valid context (since when there is no context available, we can assume `poll()`
is always True). `NodeCategory.items()`, however, must accept NULL context, so if
you use custom `items` callable for your custom node categories, you may need
to update it (as was done here for builtin `node_group_items()`).

d5f1b9c222 Multi-View and Stereo 3D
Official Documentation:
http://www.blender.org/manual/render/workflows/multiview.html

Implemented Features
====================
Builtin Stereo Camera
* Convergence Mode
* Interocular Distance
* Convergence Distance
* Pivot Mode

Viewport
* Cameras
* Plane
* Volume

Compositor
* View Switch Node
* Image Node Multi-View OpenEXR support

Sequencer
* Image/Movie Strips 'Use Multiview'

UV/Image Editor
* Option to see Multi-View images in Stereo-3D or its individual images
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images

I/O
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images

Scene Render Views
* Ability to have an arbitrary number of views in the scene

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

e15cdec2d4 New compositor node "Sun Beams"
This allows adding a "fake" sun beam effect, simulating crepuscular rays
from light being scattered in a medium like the atmosphere or deep water.
Such effects can be created also by renderers using volumetric lighting,
but the compositor feature is a lot cheaper and is independent from 3D
rendering. This makes it ideally suited for motion graphics.

The implementation uses am optimized accumulation method for gathering
color values along a line segment. The inner buffer loop uses fixed
offset increments to avoid unnecessary multiplications and avoids
variables by using compile-time specialization (see inline comments
for further details).
