Because of our release soon, feature has been added behind the Debug Menu.
CTRL+ALT+D and set it to -1. Or commandline --debug-value -1.
When debug set to -1, you can put the viewport to 'render' mode, just like
for Cycles. Notes for testers: (and please no bugs in tracker for this :)
- It renders without AA, MBlur, Panorama, Sequence, Composite
- Only active render layer gets rendered. Select another layer will re-render.
- But yes: it works for FreeStyle renders!
- Also does great for local view.
- BI is not well suited for incremental renders on view changes. This only
works for non-raytrace scenes, or zoom in ortho or camera mode, or for
Material changes. In most cases a full re-render is being done.
- ESC works to stop the preview render.
- Borders render as well. (CTRL+B)
- Force a refresh with arrow key left/right. A lot of settings don't trigger
re-render yet.
Tech notes:
- FreeStyle is adding a lot of temp objects/meshes in the Main database. This
caused DepsGraph to trigger changes (and redraws). I've prepended the names
for these temp objects with char number 27 (ESC), and made these names be
ignored for tag update checking.
- Fixed some bugs that were noticable with such excessive re-renders, like
for opening file window, quit during renders.
To achieve this, some code (callbacks and search button creation) was moved from wm_operators.c to interface/interface.c, and a new UI function was added, uiDefSearchButO_ptr.
Note: This new code uses the fact that uiButHandleFunc callbacks get executed before operator when one of its arg is the button itself!
Many thanks to Campbell who helped me a lot with this patch!
Cleanup: also removed two unused pointers from uiBut struct.
render of objects could slow things down when redrawing the view each time a new
sample is displayed.
Now it does a partial redraw of the viewport with only the render border area,
skipping OpenGL object drawing while the render is refining.
The feature "Keep Session" was also loading that session when you double-click
on a .blend to open it, or when a .blend file was on commandline.
Moved this feature to the main() in creator.c, so it can check on it properly, skipping the
kept session when a file was loaded.
* Fix precision overflow issue with overlay previews,
* Expose alpha mask mapping to UI (still not functional but coming soon).
* More overlay refactoring:
Overlay now does minimal checking for texture refresh.
Instead, we now have invalidation flags to set an aspect of the brush
overlay as invalid. This is necessary because this way we will be able to
separate and preview different brush attributes on the overlays, using
different textures:
These attributes/aspects are:
Primary texture (main texture for sculpt, vertex, imapaint)
Secondary texture (mask/alpha texture for imapaint)
Cursor texture (cursor texture. It involves brush strength and curves)
Modified the relevant RNA property update functions and C update callback
functions to call the relevant cursor invalidation functions instead
of checking every frame for multiple properties.
Properties that affect this are:
Image changes, if image is used by current brush,
Texture slot changes, similarly
Curve changes,
Object mode change invalidates the cursor
Paint tool change invalidates the cursor.
These changes give slightly more invalidation cases than simply
comparing the relevant properties each frame, but these do not occur in
performance critical moments and it's a much more elegant system than
adding more variables to check per frame each time we add something on
the system.
- GLSL shader wasn't aware of alpha predivide option,
always assuming alpha is straight. Gave wrong results
when displaying transparent float buffers.
- GLSL display wasn't aware of float buffers with number
of channels different from 4, crashing when trying to
display image with different number of channels.
This required a bit larger changes, namely now it's
possible to pass format (GL_RGB, GL_RGBAm GL_LUMINANCE)
to glaDrawPixelsTex, This also implied adding format to
glaDrawPixelsAuto and modifying all places where this
functions are called.
Now GLSL will handle both 3 and 4 channels buffers,
single channel images are handled by CPU.
- Replaced hack for render result displaying with a bit
different hack.
Namely CPU conversion will happen only during render,
once render is done GLSL would be used for displaying
render result on a screen.
This is so because of the way renderer updates parts
of the image -- it happens without respect to active
render layer in image user. This is harmless because
only display buffer is modifying, but this is tricky
because we don't have original buffer opened during
rendering.
One more related fix here was about when rendering
multiple layers, wrong image would be displaying when
rendering is done. Added a signal to invalidate
display buffer once rendering is done (only happens
when using multiple layers). This solves issue with
wrong buffer stuck on the display when using regular
CPU display space transform and if GLSL is available
it'll make image displayed with a GLSL shader.
- As an additional change, byte buffers now also uses
GLSL display transform.
So now only dutehr and RGB curves are stoppers for
using GLSL for all kind of display transforms.
- pass string size to BLI_timestr() to avoid possible buffer overrun.
- quiet warning for mingw.
- include guards for windows utf conversion funcs.
- fix for mistage in edge-angle-selection check.
- some style cleanup.
In text editor, the CTRL+F find now opens property region (or keeps it) and
activates the search button for input.
That's already nice! But next step should be to do a search on exit of
the button (or while typing). That's stuff I need Campbell to help with though.
Notes:
- Probably Py api for property buttons could get an "operator=" arg?
- The warning menu "not found" should go away
- I also suggest to make "wrap" search default for new editors
This commit basically implements frames prefetching for
movie clip datablock.
Number of frames to be prefetched is controlled in User
Preferences, System tab, Prefetch Frames option.
Currently prefetching is destructive-less for movie cache,
meaning mo frames will be removed from the cache when while
prefetching. This is because it's half of simplier to
implement, but it also makes sense from tracking point of
view -- we could want to playback in both directions and
removing frames from behind time cursor is not always a
good idea.
Anyway, smarter prefetching strategy could be developed
later.
Some implementation notes:
- Added MEM_CacheLimiter_get_memory_in_use function to get
memory usage of specified memory limiter.
- Fixed prototype of MEM_CacheLimiter_get_maximum which
was simply wrong (used wrong data type for output).
- Added some utility functions to movie clip and movie
cache for direct cache interaction and obtaining cache
statistics.
- Prefetching is implemented using general jobs system.
which is invoking from clip draw function.
- Prefetcing will stop as soon other job or playback starts.
This is done from performance point of view. Jobs will
likely require lots of CPU power and better to provide
whole CPU to it.
Playback is a bit more complicated case. For jpeg sequence
playback prefetching while paying back is nice. But trying
to prefetch heavy exr images and doing color space
conversion slows down both playback and prefetching.
TODO:
- Think of better policy of dealing with already cached frames
(like when cached frames from other clips prevents frames
from current clip to be prefetched)
- Currently a bit funky redraw notification happens from
prefetch job. Perhaps own ND_ is better to have here.
- Hiding clip while prefetch is active in theory shall stop
prefetching job.
- Having multiple clips opened on file load will prefetch
frames for only one of them.
To make circle select allow pass-through for view events, several issues have to be
tackled.
1) other modal ops run on top (border select),
2) middlemouse is used now
3) and what for tablet/trackpad or people without middlemouse?
The MMB deselection for border/circle is not optimal now... needs rethinking this.
Better would be to check on non-persistant-modality for circle, to start with gesture style
event like lasso or border can do now.
Zooming in on images in Image window now shows pixels again (was filtered).
Now the glaDrawPixelsTex() and glaDrawPixelsAuto() have an argument to
define if images should zoom in with linear filter, or draw pixels.
This patch allows Blender to display i18n monospace font in the text
editor and the Python interactive console. Wide characters that occupy
multiple columns such as CJK characters can be displayed correctly.
Furthermore, wrapping, selection, suggestion, cursor drawing, and
syntax highlighting should work.
Also fixes a bug [#34543]: In Text Editor false color in comment on cyrillic
To estimate how many columns each character occupies, this patch uses
wcwidth.c written by Markus Kuhn and distributed under MIT-style license:
http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
wcwidth.c is stored in extern/wcwidth and used as a static library.
This patch adds new API to blenfont, blenlib and blenkernel:
BLF_get_unifont_mono()
BLF_free_unifont_mono()
BLF_draw_mono()
BLI_wcwidth()
BLI_wcswidth()
BLI_str_utf8_char_width()
BLI_str_utf8_char_width_safe()
txt_utf8_offset_to_column()
txt_utf8_column_to_offset()
- RGBA images (without alpha) now don't draw with alpha blending enabled
- Checkerboard backdrop for alpha images now shows on size of image
- Window always clears now, in very dark grey (so you can see black)
- On resizing window, the aspect of image is being kept, keeping the
image always visible within the window frame
- Image now centers OK.
- On pause, playback now halts (it was drawing same image all the time)
This adds border option to compositor, which affects on
a backdrop and viewer nodes, which is useful for faster
previews and tweaks.
Final compositing still happens for the whole frame, but
if it'll be needed it's not so difficult to support it
as well.
To use border there's Ctrl-B shortcut in the compositor
editor, which i used to define region you want to restrict
compositing to. There's also "Viewer Border" option in
the N-panel in case you'll want to disable border
compositing.
Some areas could be cleaned a bit, like ideally it shall
not be viewer image clearing in viewer_border_update RNA
callback, but currently it's not so much clear how to
make it the same fast as simple memset and glue it
somehow to compositor. Will think of nicer solution a
bit later.

More use of bool type, necessitating adding inclusion of BLI_utildefines.h, or moving it up in the inclusion order if it was already included, in various places
- storage.c: make some variables only used in bli_builddir local to that
- storage.c: BLI_file_descriptor_size should allow 0 as a valid file descriptor
- path_util.c: make pointers to non-reentrant storage returned from folder routines const, necessitating making variables holding these returned pointers const elsewhere as well
- path_util.c: BLI_string_to_utf8 closes iconv context in case of conversion error
- blf_lang.c: fill_locales routine now has its own "languages" local variable to construct paths (was stealing internal storage belonging to BLI_get_folder before)
