This was causing blender to segfault.
We now add create a new collection and link to the layer before adding
the new object
(also included unittests, and requires updated lib/tests)
This adds an option to force fields of type "Force", which enables the
simulation of gravitational behavior (dist^-2 falloff).

Differential Revision: https://developer.blender.org/D2389
A group of object groups can be formed by means of the dupli_group option in
the Object properties window. The present revision extends the Selection by
Group option in the Freestyle Line Set so as to support not only flat object
groups but also nested groups.
This commit adds a way to debug Cycles motion blur issues which
are usually happening due to something crazy happening in between
of frames. Biggest trouble was that artists had no clue about
what's happening in subframes before they render. This is at
least inefficient workflow when dealing with motion blur shots
with complex animation.
Now there is an option in Time Line Editor which could be found
in View -> Show Subframe. This option will expose current frame
with it's subframe to the time line editor header and it'll allow
scrubbing with a subframe precision in time line editor.
Please note that none of the tools in Blender are aware of
subframe, so they'll likely be using current integer frame still.
This is something we don't consider a bug for now, the whole
purpose for now is to give a tool for investigation. Eventually
we'll likely tweak all tools to be aware of subframe.
Hopefully now we can finish the movie here in the studio..
I didn't manage to get the proper object context in the collection
properties editor. That said I got it working for now in a temporary way
since this will change once we get workspaces anyways
(see changes in buttons_context.c and
rna_scene.c::rna_LayerCollection_mode_settings_get)
I still need to handle the merging of the settings. I will find a
provisory solution while we wait for depsgraph.
(also layer_collection_create_mode_settings_object and layer_collection_create_mode_settings_edit could probably be elsewhere - under draw/engines likely)
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)
Design Documents
----------------
* https://wiki.blender.org/index.php/Dev:2.8/Source/Layers
* https://wiki.blender.org/index.php/Dev:2.8/Source/DataDesignRevised
User Commit Log
---------------
* New Layer and Collection system to replace render layers and viewport layers.
* A layer is a set of collections of objects (and their drawing options) required for specific tasks.
* A collection is a set of objects, equivalent of the old layers in Blender. A collection can be shared across multiple layers.
* All Scenes have a master collection that all other collections are children of.
* New collection "context" tab (in Properties Editor)
* New temporary viewport "collections" panel to control per-collection
visibility
Missing User Features
---------------------
* Collection "Filter"
Option to add objects based on their names
* Collection Manager operators
The existing buttons are placeholders
* Collection Manager drawing
The editor main region is empty
* Collection Override
* Per-Collection engine settings
This will come as a separate commit, as part of the clay-engine branch
Dev Commit Log
--------------
* New DNA file (DNA_layer_types.h) with the new structs
We are replacing Base by a new extended Base while keeping it backward
compatible with some legacy settings (i.e., lay, flag_legacy).
Renamed all Base to BaseLegacy to make it clear the areas of code that
still need to be converted
Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp
* Unittesting for main syncronization requirements
- read, write, add/copy/remove objects, copy scene, collection
link/unlinking, context)
* New Editor: Collection Manager
Based on patch by Julian Eisel
This is extracted from the layer-manager branch. With the following changes:
- Renamed references of layer manager to collections manager
- I doesn't include the editors/space_collections/ draw and util files
- The drawing code itself will be implemented separately by Julian
* Base / Object:
A little note about them. Original Blender code would try to keep them
in sync through the code, juggling flags back and forth. This will now
be handled by Depsgraph, keeping Object and Bases more separated
throughout the non-rendering code.
Scene.base is being cleared in doversion, and the old viewport drawing
code was poorly converted to use the new bases while the new viewport
code doesn't get merged and replace the old one.

This revision extends the functionality of the "Fill Range by Selection" button in
the "Distance from Camera/Object" modifiers so that only selected mesh vertices
in the edit mode are taken into account (instead of considering all vertices when
in the object mode) to compute the min & max distances from the reference.
This will give users much finer control on the range values.
Distance calculation performed by the "Fill Range by Selection" button of the
"Distance from Camera" color, alpha and thickness modifiers was incorrect,
limiting the usefulness of the functionality.
The problem was that the distance between the camera and individual vertex
locations was calculated in the world space, which was inconsistent with the
distance calculation done by the modifiers in the camera space.
New options to define the style of the animation paths in order to get
better visibility in complex scenes.
Now is possible define the color, thickness and several options relative
to the style of the lines used to draw motion path.
Experimental option for the Reproject Strokes operator to project strokes on to
geometry, instead of only doing this in a planar (i.e. parallel to viewplane) way.
The current implementation is quite rough, and may need to be improved before it
is really ready for use. Potential issues:
* Loss of precision (i.e. stairstepping artifacts) from the 3D -> 2D -> 3D conversion
as we don't have float version of one of the projection funcs
* Jagged depth if there are gaps, since it will default back to the 3d-cursor plane
if no geometry was found (instead of doing some fancy interpolation scheme)
* I'm not sure if it's that useful for adapting GP strokes to deforming geometry yet...
This operator adds a new frame with nothing in it on the current frame.
If there is already a frame there, all existing frames are shifted one frame later.
Quite often when animating, you may want a quick way to get a blank frame,
ready to start drawing something new. Or maybe you just need a quick way to
add a "placeholder" frame so that a suddenly-appearing element does not show
up before its time.
To make it faster to try different interpolation curves, there's a new operator
"Remove Breakdowns" which will delete all breakdowns sandwiched by normal
keyframes (i.e. all the ones that the previous run of the Interpolation op created)
This commit introduces the ability to use the Robert Penner easing equations
or a Custom Curve to control the way that the "Interpolate Sequence" operator
interpolates between keyframes. Previously, it was only possible to get linear
interpolation between the gp frames.
Workflow:
1) Place current frame between a pair of GP keyframes
2) Open the "Interpolate" panel in the Toolshelf
3) Choose the interpolation type (under "Sequence Options")
4) Adjust settings (e.g. if you're using "Custom Curve", use the curvemap widget
to define the way that the interpolation proceeds)
5) Click "Sequence" to interpolate
6) Play back/scrub the animation to see if you've got the result you want
7) If you need to make some tweaks, undo, or delete the generated keyframes,
then repeat the process again from step 4 until you've got the desired result.
