A counterpart / inverse to Verbose, is meant to be used by plugins to
suppress all warnings.
This flag was already used by the ShaderConverter APIs. Fonts don't have
any flags (and don't have any verbose output or warnings at the moment
either), so there it isn't added; audio importers are in a maintenance
mode with no new features added as I'll be eventually merging them with
the general importer interface in Trade.
I was abusing the API and passing a negative pitch there to not have to
invert the image by hand. It stopped working in 2.23 when they hardened
the argument checking and, while working correctly, this feature was
accidental and undocumented.
Unfortunately it broke silently, because the API returned nullptr and
SDL_SetWindowIcon(..., nullptr) is then resetting an icon to nothing. So
I'm adding an internal assertion there now. Hopefully it doesn't start
blowing up for some reason again, heh.
For more robust handling of non-owning *Data instanced and refcounting
in Python bindings I need to differentiate between, say, a MeshData
referencing global memory (such as Primitives::cubeSolid()) and MeshData
referencing just some temporary allocation or another MeshData (such as
the output of MeshTools::filterOnlyAttributes()).
It compiles on GLES2 as well, but there it hits the massive PITA of
being unable to render to LUMINANXCE formats and GL_RED formats not
really being available everywhere.
I don't have the patience to fix that, and almost nobody needs to use
ES2 platforms nowadays, so this isn't really a priority.
So one can directly read it back on GLES without having to wrap the
texture in a framebuffer again.
This change also puts the framebuffer completeness check *before* the
clear() and bind() which makes it no longer emit a GL error. The error
is still silent though, which isn't nice. Gotta fix that eventually as
well.
The UBO definitons are not tied to GL in any way, so they should be
available always. MeshTools::generateLine() now is as well, and this
made the tests fail to link on ES2 builds due to the debug operator not
being present.
This is unfortunately a breaking change to compileLines(), which now
takes the output of generateLines() instead of a line mesh. There's a
new assertion that'll blow up if the code is used the previous way,
sorry for the breakage.
What's however very useful about this change is that now it's possible
to take those generated line meshes and concatenate() them together,
achieving what's otherwise not implemented yet, such as drawing several
disconnected line strips or loops together.
It's all still partially private (the custom mesh attribute names are)
and I'm marking both APIs as experimental now to hint that it's not in
the final form/functionality yet. In particular, the data layout
optimizations described in the shader docs aren't used by these tools
yet, and if/once the line-specific vertex attributes become builtin,
compileLines() will not need to exist anymore as compile() will handle
that directly.
Took me a while to realize that tying this to a certain hardcoded field
isn't a good idea. The new variant is useful also for example for
getting absolute light positions or just whatever else. Besides taking a
SceneField there's now also an overload taking a field ID to avoid
double lookups. The only behavioral difference compared to the old API
is that the field is now required to exist, instead of the API being a
silent no-op if not present.
Eventually these APIs may get further extended to take a BitArrayView of
objects for which to calculate the transforms, for example to take only
meshes that are a part of the hierarchy, or meshes that satisfy an
arbitrary other condition. Which will also resolve the remaining
concerns with the API. I'm still keeping it marked as experimental tho,
the usefulness isn't set in stone yet.
The old APIs are marked as deprecated and implemented using the new
ones.
So people new to the plugin stuff can quickly get to usage introduction
and code snippets. The plugins alone don't list anything like that and
it may be *very* confusing otherwise.
Ugh, that whole code looks like commited halfway through, without
even looking at it again. Comments making no sense, variables mutating
for no reason...
It dates back to 145e055b41 when the code
was written back in 2020. Probably just some debugging leftover, as the
array gets fully overwritten later.
The only vaguely related case where zero-initialization and/or garbage
memory would matter is e496241290, but
that one isn't the case for fuzzy comparison -- here each attribute gets
handled separately and any padding is skipped.
It's included in the MagnumGL library because it shouldn't be compiled
if MAGNUM_TARGET_GL is disabled. So, in other words, this was breaking
the GL-less build.
Among other things this makes it possible to use Utility::copy() instead
of a manual loop and grow arrays with std::realloc() instead of always
new'ing-copy-deleting because Containers::Pair is trivially copyable.
This fixes a "visibility attribute ignored" warning in
MultisampleTexture.cpp on newer GCC and makes the three behave
consistently without having to perform crazy ordering between function
definitions and explicit template instantiation.
It's horrible, yes, but I had to resort to the same approach in
StringView.cpp because in general every other variant was failing in
some way in some compilers. I hate everything about this.
This means I (and people making their own plugins) don't need to go and
update each and every plugin once the version in the interface string
gets bumped after a (silent) ABI break. Such as when new virtual
functions get added, as those often lead to strange crashes if the
plugins don't get rebuilt after.
The plugins will now use this macro, which means they'll
automatically embed an interface string that was present in the base
class header at build time. However, when the base class updates, the
previous string is still embedded in the plugin binary, which will then
fail to load -- this being automatic doesn't mean the original purpose
is lost. Subsequently rebuilding the plugins from source will make them
pick up the updated interface string again.
Integer / packed formats are the majority of uses for this utility, and
for them the additional complexity with NaN and infinity handling isn't
needed at all.
Running ShadersMeshVisualizerGLTest with this change in a Debug build
led to its runtime being reduced by about 35%, the total test time
excluding benchmarks went from 14.5 seconds to 11. Not bad.
The change won't make any difference in Release, but in Debug builds it
avoids calling into set() for every element. This function showed up
pretty high in profiler output for DebugTools::CompareImage, now it
doesn't anymore. In particular, for ShadersMeshVisualizerGLTest it
results in ~10% reduction in run time, which is quite significant.
The
(size - 1)/8 + 1
expression is the same as
(size - 1)/8 + 8/8
which is the same as the following in all cases except when size == 0,
for which it underflows:
(size - 1 + 8)/8 == (size + 7)/8
To avoid needless surprises, I'm changing to what's used everywhere
else, including the BitArray, and also reusing the already-calculated
value for the _data array size.
The article this API was originally based on assumes a scenario which
just *isn't* matching usual practices here, giving wrong results. Too
bad I didn't spend more time questioning the proof there and just
blindly assumed it's correct because everyone said so.
Won't be typing all that reasoning again in the commit message, see the
changelog entry and the comment in the test for details.
Taking Animation::TrackViewStorage wasn't really a good idea, as it
wasn't solving anything -- in order to create it, there needs to be a
TrackView of a concrete type first anyway, and even then it required a
lot of additional verbose typing.
The new constructors take basically what TrackView takes, plus there's
additionally a constructor that takes a typeless value view together
with explicitly specified value and result types, allowing a truly
type-erased usage. On the other hand, the templated variants directly
deduce the types without any additional typing, making the construction
similarly straightforward to e.g. SceneFieldData.
In case of the type-erased constructors, if the interpolator function
isn't supplied explicitly, an implicit one is picked based on the value
type, result type and interpolation. Not all combinations make sense of
course, so this is a new assertion point, however compared to the
previous way where the interpolator was picked from a *typed* TrackView,
this doesn't add any new restriction -- what asserted there, asserts now
as well, and additionally you can't have e.g. a Quaternion track with a
boolean result. I may also be eventually adding assertions to check that
the target name matches the result type -- so e.g. a rotation isn't
specified as an integer and such. Compared to newer APIs like MeshData,
MaterialData or SceneData the AnimationData API has a significant lack
of sanity asserts like this.
Instead of storing Animation::TrackViewStorage directly it now contains
the view pointers, strides and size (where the size is shared by both
keys and values) together with packing the non-pointer values into
existing paddings. Together with reducing the keyframe count to 32 bits
and strides to 16 bits (which is consistent with MeshData and
SceneData), this reduces the size from 80 bytes to 48.
Not using TrackViewStorage also means we can directly accept the
key/value views in constructors, significantly improving the usability.
This also makes it possible to add support for (constexpr) offset-only
track data and thus easy serializability, again similarly to
MeshAttributeData and SceneFieldData.
