This also resolves the (unlikely) issue of undo having uninitialized
zbuf data, now it's cleared instead.
|
|
|
|
|
|
Update image undo to store buffers for each step:
- Undo buffers share tiles to avoid using too much memory.
- Undo support for different sized buffers
allowing operations such as crop or resize.
- Paint tiles have been split into separate API/storage.
- Painting speed wont be impacted significantly
since storing the extra tiles is done after the stroke & only
for the first undo step.
Resolves T61263, see D5939 for details.

Since our ffmpeg is built with openjpeg support and thus can decode jpeg
2000 (in both J2K and JP2 codec flavors as well as high bitdepths), added
these extensions to the supported list.
Also IMB_ispic > IMB_ispic_type > imb_is_a_jp2 was only testing for jp2,
now do both jp2/j2k.

Units should be explicit, and not left to be guessed by the reader.
The field is only used in a single C file, so it's a relatively low-risk
change.

The problematic video from T68091 clearly has an invalid stream duration
(it would be 55 centuries long if interpreted at 30 FPS, and given that
it was recorded with an Android 9 device, it's unlikely that recording
started that long ago). I've added a heuristic to check the stream
duration against the container duration; if the stream is more than 4x
longer than the container, Blender now falls back to the container
duration.
We could use MIN(stream duration, container duration), but there might
be video files out there where the container duration is less precise
than the stream duration; they are measured in different units of time
(microseconds for the container vs. frames for the stream).
Includes a unit test for the above heuristic.

This was introduced in FFmpeg lavf 55.1.100 in 2013. For systems that are
still on LibAV or older FFmpeg there is a fallback implementation that
performs the same guess as we did before in `av_get_r_frame_rate_compat()`.

There is now a clearer distinction between `video_stream` (the stream itself)
and `video_stream_index` (its index), and no more repetition of accessing
the same item of an array. This also makes the code a bit more readable in
preparation for an upcoming functional change.

This partially reverts commit 0b2d1badecc48b5cbff5ec088b29c6e9acc5e1d0
Post increment can deep-copy for C++ iterators, while in my own checks
GCC was able to optimize this to get the same output,
better follow C++ best practice and use pre-increment for iterators.

When the result isn't used, prefer post increment/decrement
(already used nearly everywhere in Blender).

With Blender 2.80 we introduced a more flexible matcap system. One
change we did was to multiply the matcap with the base color that was
shaded. As matcaps contains diffuse and specular lighting in a single
texture this lead to rendering artifacts. Artists were complaining that
everything looked to metalic.
We now support a separate `diffuse` and `specular` pass for matcaps.
`shaded_color = diffuse_light * base_color + specular_light`
For matcaps to support this feature they need to be multilayer openexr
files with 2 renderpasses (named `diffuse` and `specular`). In the future
we can change this to first pass/second pass in stead of this naming
convention.

Like Blender renders without a Z channel. The single layer case assume that channel
names are just R/G/B/A without any layer name prefix, and would not read channels
like "Image.R".
Carefully tested for regressions with the openexr project tests images, so this
should be safe.

Now texture storage of images is defined by the alpha mode of the image. The
downside of this is that there can be artifacts near alpha edges where pixels
with zero alpha bleed in. It also adds more code complexity since image textures
are no longer all stored the same way.
This changes allows us to keep using sRGB texture formats, which have edge
darkening when stored with premultiplied alpha. Game engines seems to generally
do the same thing, and we want to be compatible with them.

* Replace Log view transform with Filmic Log.
* Remove Rec.709, DCI-P3 displays that were incomplete and outdated.
* Remove outdated RRT and Film transforms, replaced by Filmic.
* Remove camera responsive curves that don't work with HDR colors.
* Rename Default view transform to Standard.
We're breaking compatibility now for 2.80, so that we can add future
improvements on a clean config.
Part of the code was contributed by George Vogiatzis in D4782.

This also replaces the Use Alpha setting. We now have these alpha modes:
* Straight: store RGB and alpha channels separately with alpha acting as a
mask, also known as unassociated alpha.
* Premultiplied: transparent RGB pixels are multiplied by the alpha channel.
The natural format for renders.
* Channel Packed: different images are packed in the RGB and alpha channels,
and they should not influence each other. Channel packing is commonly used
by game engines to save memory.
* None: ignore alpha channel from the file and make image fully opaque.
Cycles OSL does not correctly support Channel Packed and None yet, we are
missing fine control over the OpenImageIO texture cache to do that.

The previous behavior here was wrong for some specific combinations of
settings, non-color RGB channels should never be affected by the alpha
channel.

This also makes `IDP_CopyProperty` the "opposite"
of `IDP_FreeProperty`, which is what I'd expect.
Two refactoring steps:
* rename IDP_FreeProperty to IDP_FreePropertyContent
* new IDP_FreeProperty function that actually frees the property

Cycles now uses the color space on the image datablock, and uses OpenColorIO
to convert to scene linear as needed. Byte images do not take extra memory,
they are compressed in scene linear + sRGB transfer function which in common
cases is a no-op.
Eevee and workbench were changed to work similar. Float images are stored as
scene linear. Byte images are compressed as scene linear + sRGB and stored in
a GL_SRGB8_ALPHA8 texture. From the GLSL shader side this means they are read
as scene linear, simplifying the code and taking advantage of hardware support.
Further, OpenGL image textures are now all stored with premultiplied alpha.
Eevee texture sampling looks a little different now because interpolation
happens premultiplied and in scene linear space.
Overlays and grease pencil work in sRGB space so those now have an extra
conversion to sRGB after reading from image textures. This is not particularly
elegant but as long as engines use different conventions, one or the other
needs to do conversion.
This change breaks compatibility for cases where multiple image texture nodes
were using the same image with different color space node settings. However it
gives more predictable behavior for baking and texture painting if save, load
and image editing operations have a single color space to handle.

This patch implements new cache system.
Aim is to give user more control over cache, so it can be maximally
utilized. This is done through sequencer timeline side panel
in category proxy & cache.
Cached images are also visualized in timeline, controled by
sequencer timeline view->cache menu
Functional changes:
- NOT use IMB_moviecache API
- refactor names of cached image types
- each scene owns 1 sequencer cache
- merge preprocess cache into per-sequencer cache
- cache links images rendered per frame in order as they are created
- add cache content visualization tool
- add RNA properties to control the cache
