Doxygen 1.12 has no longer a completely insane matcher and discards
those as it should. With 1.8.17 classes had to be referenced with
Corrade:: but functions, typedefs and variables didn't need to be and it
was a complete utter chaos.
Amazing, I haven't been in this corner of the codebase for over six
months but the test setup and code coverage still makes it quite
straightforward to add a rather complex new feature without breaking
unrelated cases or leaving certain areas completely untested.
Partially needed to avoid build breakages because Corrade itself
switched as well, partially because a cleanup is always good. Done
except for (STL-heavy) code that's deprecated or SceneGraph-related APIs
that are still quite full of STL as well.
Such as Emscripten or Android. The hypothetical use case is converting
shader files directly on an Android device to debug things, or having a
Node.js build of a scene/image converter for "portability".
Static plugins can be linked to these if Magnum is built together with
Magnum Plugins in a CMake superproject and the plugins are then linked
via the MAGNUM_*CONVERTER_STATIC_PLUGINS CMake variable.
The fontconverter and distanceconverter tools cause a CMake error on
Emscripten as it's not currently possible to access the GPU through a
command-line Node.js app. On Android they work though.
A bit sad it took me three years to invent the right name for this
utility, heh. Also moving it together with others to a new
MeshTools/Copy.h header because *this* is the mainly useful API, not
reference() / mutableReference().
MaterialTools and SceneTools will get similar copy() APIs doing the same
thing.
That's a second deprecation of this API in a short while, sorry. This
variant is hopefully the final one, with the previous one I still had
the problem that it contained a verb, which implied that it'd
*transform* the SceneData in some way which (unlike combineFields(),
filterFields() etc.) it didn't, it just extracts some data in a certain
way. This would all cause problems when there are APIs that actually do
perform hierarchy flattening.
It's also moved to a new, more general Hierarchy.h header which will
contain other hierarchy-related APIs. It doesn't make sense to have a
tiny header with just a single function, especially given it doesn't
depend on any heavy headers on its own.
Besides that it also makes the UnsignedInt overloads the main ones, and
the Trade::SceneField secondary, as is already done everywhere else (and
the opposite way was just bad inheritance from flattenMeshHierarchy()
it seems).
This is now the preferrable way to set options to plugins that get
delegated to from other plugins, instead of
Until now there wasn't a general command line interface to pass options
to plugins that get delegated to from other plugins, such as image
converters used by scene converters. Due to that limitation, e.g.
GltfSceneConverter had to add an [imageConverter] configuration group
that it then copied over to the chosen image converter. But such
approach obviously doesn't scale -- every converter would have to do the
same, would have to repeat the whole testing process, and basically the
same would need to be done for all importers delegating to image
plugins. Nightmare.
So there's now --set, which allows arbitrary options to be set for
arbitrary plugins, and that's the preferrable way now. To avoid having
to maintain two ways to do the same, the [imageConverter] group will get
removed eventually.
The main use case is being able to specify what concrete plugin gets
used for a particular alias, e.g. to be able to use SpngImporter instead
of PngImporter for faster PNG image loading.
So far the option is implemented only here, as the imageconverter,
shaderconverter and other tools don't really deal with plugins
that delegate to other plugins. Yet.
When using the -P or -M options on a large scene, it can happen that
the conversion would fail for a small number of outliers. For example
there can be some line meshes which aren't supported by MeshOptimizer,
or there are 16-bit images not supported by a certain image conversion
plugin.
Failing the whole operation in that case may be too radical, especially
if the only alternative would be to write a Python script that deals
with the outliers in a custom way. The option simply makes the
processing step pass through the original data unchanged, which may be a
simple and good-enough solution in many of those cases.
Originally I thought I'd save plugins some time if I just give them the
custom indices directly, without being wrapped in a SceneField /
MeshAttribute enum. But in practice that didn't really save anything,
made the interfaces more error-prone due to there being no concrete type
anymore, and all code that delegates to nested importers or converters
had to re-wrap the IDs again, which is *again* error-prone.
Bumping the interface strings because this is a breaking change for the
implementations. Not for users tho, there nothing changes.
If it crashes or does some other shit, it'll cause the tool to not work
at all. If it fails to load due to whatever other issue, it'll spam the
output for no reason.
Exposes MaterialTools::phongToPbrMetallicRoughness() that got added some
time ago. Most of the code and tests is scaffolding needed for direct
material import and processing outside of the addImporterContents()
automagic, similar to what was already done for meshes and images.
In particular, adding more material conversion options such as
canonicalization or deduplication will be significantly easier now that
the basics are done and tested.
The number of items is known beforehand, so avoid unnecessary
reallocations. When mesh LODs are supported this won't be that clear
anymore, nevertheless it's never bad to pre-reserve.
Lists features, aliases as well as documented contents of the whole
configuration file. Useful to not need to look up online docs when
working on the command line.
Just a minimal support to get single-mesh conversion working with
GltfSceneConverter. The whole thing has to be subsequently reworked to
not be oriented around meshes, but this is the first step.
