Also add groups in some files.

Audio PTS was reset for each new file. This caused misalignment of video
and audio streams. In Blender, these files can't be loaded, other
players will fail to align audio and video.
Since timestamps are reset intentionally, reset also video stream
timestamps.
There were other bugs:
After timestamp was reset for audio, write_audio_frames started
encoding from timeline start until target frame, so each split video
had more audio than it should.
Also audio for last frame before splitting was written into new file.

Since 88c02bf826df FFmpeg handles are freed if image is not displayed.
This change did not work correctly if strips are inside meta strip,
because overlap did not consider meta strip boundary, only strips inside
of meta strip.
Pass frame range to `sequencer_all_free_anim_ibufs`, if strip is inside
of meta strip, frame range is reduced to fit meta strip boundary, but if
meta strip is being edited, range must be set to +/-`MAXFRAME`,
otherwise playback performance would be too bad.

The difference between G.save_over and G.relbase_valid was minor.
There is one change in functionality. When saving the default-startup
file from an already loaded blend file - future save actions will
continue to write to the originally loaded file instead of prompting
the user to select a location to save the file.
This change makes saving the startup file behave the same way
"Save a Copy" does.

There were a few unused enum values: `CU_CARDINAL` and `CU_BSPLINE`
This commit cleans them up from code as they were not used for

This builds off of rBf951aa063f7, adding a weight parameter which can
be used to change the order of items when they have the same match
score. In the future, if string searching gets a C++ API, we could
use an optional parameter for the weight, since it is not used yet.
This will be used for the node link drag search menu (D8286).

Resolving the path to a missing pose-bone (for example),
was not raising an error as it should have.
Regression introduced in f9ccd26b037d43f2490d1f0263e45e775d30473d,
which didn't update collection lookup logic to fail in the case the
key of a collection wasn't found.

This implements an optimization pass for multi-function procedures.
It optimizes memory reuse by moving destruct instructions up.
For more details see the in-code comment.
In very large fields with many short lived intermediate values, this change
can improve performance 3-4x. Furthermore, in such cases, peak memory
consumption is reduced significantly (e.g. 100x lower peak memory usage).

Use "filepath" which is the current convention for naming full paths.
- Main use "name" which isn't obviously a file path.
- BlendFileData & FileGlobal used "filename" which is often
used for the name component of a path (without the directory).

These arguments must be non-null for useful functionality,
there is no need for paranoid checks.
The return value in case of invalid input for BPY_run_string_as_number
was also wrong (casting -1 to a bool, when false was expected).

Point cloud is two separate words, this just changes comments in

This ends up including the removed headers in many unnecessary places.

This reduces the number of separate memory allocations done
by the multi-function procedure executor (which is used by the
field evaluation).
Now a linear memory allocator is used to allocate all intermediate
values. Furthermore, more buffers are reused when possible. This
reduces the total amount of allocated memory and improves
cache efficiency because the values are more likely to be in cache
already.
The performance improvement of this patch are most noticable
when few elements are processed by many functions. The situation
will improve even more with D13548, because then buffers can actually
be reused in practice. I measured up to 20% faster field evaluation
in extreme cases with this change.

Also remove unnecessary function to set a node type's
label function that duplicated its definition, and make
another function static.

Calling `foreach_field_input` on a highly nested field (we do that
often) has an exponential running time in the number of nodes.
That is because the same node may be visited many times.
This made Blender freeze on some setups that should work just fine.
Now every field keeps track of its inputs all the time. That replaces
the exponential algorithm with constant time access.

The const argument makes sense because these are the "source"
sockets, even though a const cast is necessary at one point.
The name "interface_socket" is an improvement over "stemp"
because the latter sounds like "temporary", or it confuses
the old socket template system with a node group's interface.

I assume this `butr` rectangle was used more in the past,
but currently its value is set and used less than 10 lines apart,
so it's trivial to remove 16 bytes from every node. The other
rectangles are also runtime data and could be removed, but
they are more difficult.

This reverts commit 943aed0de35621e328 and f76e04bf4d7cdce8

Most of the fields in Mesh had no comments, or outdated misleading
comments. For example, "BMESH ONLY" referred to the BMesh project,
not the data structure. Given how much these structs are used, it should
save a lot of time to have proper comments.
I also rearranged the fields in mesh to have a more logical order. Now
the most important fields come first. In the process I was able to
remove 19 bytes of unnecessary padding (31->12). I just had to
change a `short` flag to `char`.

This patch replaces `round_fl_to_int` with `floor` and adjusts the
maximum value accordingly. The call to `round_fl_to_int` is problematic
here because it messes with the probability distribution at the edges
of the value range, meaning the first and last values were only half
as common as all other values. Since `round_fl_to_int` does
`floor(val + 0.5)`, it will not introduce misbehavior in edge cases.

Improvement of the IMB_transform function by separating the UVWrapping
method from the color interpolation function. This would allow us to
perform uv wrapping operations separate from the interpolation function.
Currently this wrapping is only supported when interpolating colors.
This change would allow us to perform it on non-color image buffers.
|
|
|
|
Reduce the inner loop of IMB_transform by extracting writing to an
output buffer in a template. This reduces a branch in the inner loop and
would allow different number of channels in the future.

Use IMB_get_rect_len to solve overflow issues.

Some doc-strings were skipped because of blank-lines between
the doc-string and the symbol and needed to be moved manually.
- Added space below non doc-string comments to make it clear
these aren't comments for the symbols directly below them.

When loading huge images (30k) blender crashed with a buffer overflow.
The reason is that determine the length of a buffer was done in 32bit
precision and afterwards stored in 64 bit precision.
This patch adds a new function to do the correct calculation in 64bit.
It should be added to other sections in blender as well. But that should
be tested on a per case situation.

with the CPU and GPU
When rendering volume surfaces in unbounded worlds the volume stepping can produce large values. If used with a magic texture node the values can results in a Inf float which when used in a sin or cos produces a NaN.
To fix this the input values are mapped into the periodic range of the sin and cos functions (-2*PI 2*PI) this stops the possibility of a Inf occurring and thus the NaN. It also improves the accuracy and smoothness of the result due to loss of precision when large values are summed with smaller ones effectively removing the parts of the smaller number (i.e. those in the -2PI to 2PI range) that result in variation of the output of sin and cos.

In the `replace_mesh`/`replace_curve` etc. methods, the component
was retrieved with write access. Retrieving with write access will
duplicate the data if the component has another user. This means that
the replaced geometry data was often duplicated just to be deleted
a moment later.
I expect this would have a large impact in performance in some specific
situations when dealing with large geometry. In a scene with many small
meshes though, I didn't observe a significant difference.
This also makes replacing a geometry set's data with the same data
that's already in the set safe. It would be valid to assert for that
case instead, but this seems safer.

This node outputs the current scene time in seconds or in frames.
Use of this node eliminates the need to use drivers to control values
in the node tree that are driven by the scene time.
Frame is a float value to provide for subframe rendering for motion
blur.
