- De-duplicate code used by color management panel drawing,
moved this panel to utility file in bl_ui
- Added support of per-window color management control
which means view transform. exposure and gamma could be
set per window and all spaces would use this settings.
This is default behavior for older files now.
- Added support of color management display of movie clips
in clip editor.
Supported both texture buffer and fallback draw methods.
- Fixed default values for exposure and gamma
- Move space-being settings (such as view transform) into own
DNA and RNA structure to avoid code duplication in some areas
and save some arguments on display buffer acquiring function.
Also added some utility functions to BKE to manipulate this
settings.
- Replace static sized color managed buffer flags array with
dynamically sized array which matches actual number of displays.
Probably this flags better be transfposed so it'll support
any number of view transforms and 32 displays (currently it's
other way around). it's runtime flags only, so would be simple
to change any time.
- Added support of configurable exposure and gamma.
Changing this settings wouldn't generate new item in cache,
it'll affect on buffer with the same color spaces conversion.
It'll also run full color transform from scratch on every run,
this could be changes in a way that it'll re-use color managed
buffer, but from quick glance it doesn't give really noticeable
boost.
Currently this settings are stored as pointer in ImBuf structure
itself. Probably it make sense removing them from ImBuf and make
moviecache be able to store some kind of tags associated with
cached ImBuf.
- Fixed memory leak caused by incorrect handling of cached buffer
in cases if it was marked as dirty
- Do not use 3D LUT for RRT -- they can't be easily baked into 3D
LUT without being clamped to 0..1 space
- Make sure blender compiles without OCIO support
- Made color management cache safe for situations when one area
requested a display buffer, then some changes were done which
invalidated cache, other area requested display buffer which
changed cached buffer.
Suck case could be fatal for first used of display buffer,
which didn't happen yet because cache is being accessed from
main thread only, but better to keep this things completely
thread save to avoid headache in the future.
- Baked RRT transformations, which gives ~3-4 times boost
hopefully without visible artifacts.
- Added support of partial updates to display buffers.
This would create special context which hols display buffer
which imbuf had to the time of creating this context and
later this context would allow to run a color correction
from given linear buffer within given region.
This is being used by compositor to enable more realtime
display update when compositing.
- Added support of color management backdrop for nodes editor.
There's now special menu called display properties in N-panel
of nodes editor.
Probably this better be de-duplicated somehow, but not sure
yet how. Currently it's not so harmful to have panel for two
spaces which contains only 2 properties.
There's currently one unsolved issue with backdrop:
it's not being updated progressively when just loading the
file -- it's simply because there's no color managed display
buffer for backdrop yet, and compositor doesn't actually
know which color space to use here to generate preview to.
The transform operators in nodes will now use the unselected nodes to generate snapping points. Unlike object snapping, node snapping works for the x/y axes separately and snaps node borders to same borders of unselected nodes. The sensitive area for node borders extends over the whole view2D range, to enable simple alignment of nodes in both x and y direction.
For snap points in the node editor an additional enum value is stored to indicate the type of node border (left/right/top/bottom). This works as a constraint on possible node alignments: only same border types align with each other.
Enabled use_gridfill for edgesubdivide called by loopcut. This will break edgeslide in this specific case (intersecting faceloop), but imho makes more sense this way than the other. Very easy to revert anyway, and this should only affect this specific cornercase.
The bug is related to 31581 and the main cause is the small offset that
BM_loop_interp_from_face introduces before calculating barycentric
weights. Solved by only calculating displacement layer.
This function is used to name undo pushes in sculpt mode, was missing
some of the newer brush types. Also tweaked the switch statement so
that it will warn for future missing cases and removed extraneous
breaks.
save memory during render and cache render results.
Implementation notes:
In the render engine API it's now possible to get the render result for
one render layer only, and retrieve the expected tile size in case save
buffers is used. This is needed because EXR expects tiles with particular
size and coordinates.
The EXR temporary files are now also separated per layer, since Cycles
can't give the full render result for all render layers, and EXR doesn't
support writing parts of tiles.
In Cycles internally the handling of render buffers and multi GPU
rendering in particular changed quite a bit, and could use a bit more
refactoring to make things more consistent and simple.
The 2D Filter system now only copies the game viewport instead of the whole window. This prevents 2D Filters from grabbing data outside of the game viewport. The textures for 2D filters are now also not forced to be powers of two (if NPOT textures are supported), which can save a little bit of VRAM.
Added back face validation to BKE_mesh_validate_arrays.
This is needed because some addons (like OBJ importer) are reading
tessfaces and then converting them to ngons and validation of tessfaces
is needed before such a conversion.
Validation of faces would happen only if there's no polys in mesh.
Snapping actually was working already, but grid spacing was set to 1.0, which is basically pixel size in the node editor. Increased this to 1x grid step for fine snapping and 5x grid step for rough snapping.
Grid drawing in node editor now draws 2 levels in slightly different shades to indicate the different snapping modes better.
Node editor also supports the general use_snap tool setting to enable automatic snapping during transform. For now only the incremental snapping is supported, in future could be extended to enable alignment between nodes in a number of ways.
the idea of using methods instead of attributes is to avoid users abusing of the system calls.
Thanks Campbell Barton for reviewing and small corrections
