Triangulate with beautify caused a bug when there were existing edges
could make the bmesh-operator return an invalid face-map.
Now the beauty is calculated on the 2d-tri's resulting from polyfill,
its simpler and faster.
Edgehash was missing removal functions (remove, popkey, clear),
since it wasn't needed so far, but is based on same code as ghash which has them.
also add heap clear() method so we can reuse heaps.
(needed for upcoming fix).
note, this is for C++ code which expects a cast, (will be added later)
also add a macro for nop-expressions (EXPR_NOP),
when we never want an expression to be evaluated, but it should still be valid.
* Rename "emboss" to "widget_emboss"
* Remove duplicated UI_GetThemeColor4ubv function
I made sure version bump and Save User Settings are working correctly ;P
It turns out that several important modelling addons depend on the assumption
that Grease Pencil data gets created on the active object instead of on scene
level. This commit adds a toggle for setting whether new Grease Pencil data
is created on scene or object level.
These work as follows:
* "Scene" = The behaviour originally introduced as part of the GPencil_EditStrokes
changes. New strokes are added to the scene instead of the active object, making
it easier to manage things when working with Grease Pencil in general.
* "Object" = The previous behaviour (from 2.50 to 2.72), where new strokes are added
to the active object. This is now being reintroduced to soften the transition
for addons out there which have been doing this in a lazy/lax way so far.
Now, what may be slightly confusing are the "fallback" measures in place:
* "Scene" - To ensure that loading old files goes ok without needing a version patch,
if the active object has GPencil data, that will be used in place of the scene's
own GPencil data.
* "Object" - If there was no active object at the time of creating strokes
(for instance, if you delete the active object immediately before drawing),
GPencil data gets attached to the current scene instead.
Since some tweaks may still be needed here, I've decided to bump the subversion
number so that we have a reference point when doing version patches.
Original patch by @random (D765) with some minor work done by @campbell
and me.
At this place, I'd like call out a number of people who were involved and
deserve a big "Thank you!":
* At the first place @randon who developed and submitted the patch
* The Blendercn community which helped a lot with testing - espacially
* @yuzukyo, @leon_cheung and @kjym3
* @campbellbarton, @mont29 and @sergey for their help and advises during
* review
* @ton who realized the importance of this early on and asked me for
* reviewing
We are still not finished, as this is only the first part of the
implementaion, but there's more to come!
On second thought, it is probably still worthwhile to be able to disable GPencil
drawing on strips. By default, GPencil strokes are still shown by default now,
but they can be turned off using this option if it turns out that they are
getting in the way (e.g. a director/animator make some planning notes in the shot
at an earlier stage which are hidden for normal display now, but are still there
popping up sproadically during the animatic).
After double checking the sequencer code, there doesn't seem to be any reason to
exclude these from the sequencer previews. This makes it possible to use the
sequencer to non-destructively chain together difference Grease Pencil animated
shots together without having to render each image sequence first, allowing for
a smoother workflow.
Just in case the initial assumption isn't entirely correct, I've put in place
an extra arg to the relevant functions which can be hooked up to a suitable
option on the scene strip later to turn this on/off as needed.
The Toggle Muting operator was missing code to tag the animation to get recalculated.
This was also missing from a few other operators too, including Snap, and
Add/Paste FModifiers .
ImageFFmpeg objects will not refresh properly because the image
file is closed immediately after creation. Therefore refresh()
should have no effect on them.
This was causing problems with ImageMix using ImageFFmpeg as
sources: refreshing the ImageMix object is required to update
the mix but it has the side effect of refreshing the underlying
sources, hence the need to skip refresh on fixed images.
Really bad issue which meant code could fetch an image buffer from the
stored cache and modify it. Generally sequence image buffers could come
from the cache and should not be modified directly. Easily solved by
scaling a copy of the original.
Couple of issues:
- Fist/last frame calculation was wrong
- Keyframe selection might silently fail leading to unpredictable math
errors all over the place. Now if keyframe selection fails solver wouldn't
run.
Buffers should actually be cleared before running operations on them,
but this doesn't work for some reason.
Note also that the sunbeams node can show some creases and hard aliasing
when the source point is close to a bright area with strong gradient.
To fix this a better filtering algorithm, dithering or ray sampling
would need to be implemented. In the meantime simply blurring the
sunbeams result a bit should help (or simply avoid putting the source on
a bright spot).
