Also remove duplicate & mismatching comments from grease-pencil header.
Keep comments close to implementation to avoid getting out of sync.

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.

Patch D2270 by Anthony Edlin (@krash), thanks.
|
|
Ray-plane intersection routine GeomUtils::intersectRayPlane() was used with an
unnormalized direction vector as input.
|
|
We were calling BLI_remlink and then BLI_insertlinkbefore/after quite often. BLI_listbase_link_move simplifies code a bit and makes it easier to follow. It also returns if link position has changed which can be used to avoid unnecessary updates.
Added it to a number of list reorder operators for now and made use of return value. Behavior shouldn't be changed.
Also some minor cleanup.

coverity).
Error: `origin` and `edge` args were swapped in final `FindOccludee()` call of `ViewMapBuilder::ComputeRayCastingVisibility()`
Cleanup: main for loop in `Strip::createStrip()` was really confusing (though correct),
generated a false positive in coverity scan, now should be cleaner how it loops over its vprev/v/v2
triplet of consecutive items.

Group membership testing for including/excluding feature lines was not
accounting for object names possibly further qualified by library file
paths.
Also fixed a few potential (but unlikely) references of uninitialized
variables.
A big thank to Bastien Montagne for the insight on the cause of the
problem and how to fix it.

(A - A).norm() is always 0 so condition is always true.
(A - B).norm() and (B - A).norm() both compute the same distance so I
picked one to match surrounding code.

Now test_object_materials only handles one object. New test_all_objects_materials
checks the whole bmain->object list for cases where it is actually needed.
Should avoid some useless looping over all objects!

Two were actual bugs, though they existed only in unused code:
* In Freestyle it was unintentionally copying a scene rather than referencing it.
* In BLI_array_store_is_valid there was use of uninitialized memory.

RenderLayer.
FSAA sample files in EXR format are no longer always updated (after some
changes between 2.73 and 2.74 releases), and the reported bug was caused
by old samples from a previous frame that were being merged by mistake.
The present revision addresses the documented issue by entirely skipping
the rendering of auto-generated scenes when there are no Freestyle strokes
to render, which suppresses sample merging of the render layers that were
not rendered.
|
|
The addressed issue is a regression from Blender 2.75, after the internal
switch from double to single precision floating-point numbers in the
Freestyle code base. Face normal calculations require the higher
precision during the computations, even though the results can be stored
as single precision numbers.
|
|
This fixes reported issue, but there could be more of those hidden in Freestyle code,
it did not handle user refcount at all (and the fact it by-passes BKE in some places
for efficiency does not help here).
Note that this should be relatively harmless, since freestyle uses own Main during
render, so everything is cleaned up in the end in any case... But better try to
handle IDs correctly here too. :)

Also fix inconsistency for freestyle translation - we use IFACE_ everywhere
(TIP_ may be more suited, but let's be consistent first!).

We have callbacks for that, they also do some checks and help ensure things are done
correctly. Only place where this is assumed not true is blenloader (since here we
may affect refcount of library IDs as well...).

The reported crash was confirmed as a segmentation fault in std::sort().
The cause of the crash was traced down to a binary comparison function
that was not satisfying the so-called strict weak ordering requirements of
the C++ standard sorting function. Specifically, the comparison operator
has to return false when two objects are equivalent (i.e., comp(a, a) must
be false), but that requirement was not met.
Since the binary comparison operator in question could be a user-defined
Python function, here a safety measure is implemented in the C++ layer to
make sure the aforementioned requirement is always satisfied.

Also fixed a potential crash in the copy constructor case.

ImBuf types were getting stored as bitflags in a 32bit integer which had
already run out of space. Solved the problem by separating file type to
an ftype enum, and file specific options to foptions.
Reviewed by Campbell, thanks a lot!

This patch introduces a couple new stroke modifiers. The ones currently implemented are based on prototypes by @kjym3 and myself.
The new modifiers:
- Tangent
- Thickness noise
- Crease Angle
- Simplification
- Curvature 3D
The documentation for these new modifier types can be found [[ http://www.blender.org/manual/render/freestyle/parameter_editor/index.html | in the manual ]]:
