Matching what's in MeshTools, because I need them to implement other
algorithms that match what's in MeshTools. In other words no idea why I
didn't make these along with copy() already.
To be used with the recently added MaterialTools::removeDuplicates() for
example, or internally by other upcoming scene tools such as importer
filtering.
Same reasoning as before, the verb suggests it's transforming the
SceneData in some way, which isn't true, it just retrieves the data in a
certain way. And if an API that actually operates on SceneData got
added, it would be easily confused with this one.
Plus, the "order" isn't just one, this orders objects so they're grouped
with a common parent, but what if I wanted to instead order depth first?
Thus it's explicitly saying this is a breadth-first order.
The API got moved to the Hierarchy.h header, removing a need for a
dedicated file and test.
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).
It'll be soon needed by other tools and library users as well. The main
difference compared to the original internal API is that the
detection for shared mapping views now takes also sizes and strides into
account, without relying on just the data pointer.
Some additional robustness checks are needed regarding fields that have
mapping sharing enforced (as otherwise it'll fail in the SceneData
constructor which isn't nice), that'll be done in subsequent commits.
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.
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.
Funny/sad that this possibility took me so long to realize. Until now it
was "you can have command-line utilities or static plugins but never
both", and only with CMake 3.13+ it was possible to link static plugins
to these executables from outside. Now it's a builtin and supported
option.
It was quite a pile, and all of it was written just once, relying only
on hopefully-available model files that would hopefully touch most code
paths. Which means, extremely annoying to make changes in.
I extracted the code to a header that can be tested with a mocked-up
importer and without having to execute the utility itself, deduplicated
the image info printing code, fixed various inconsistencies (such as
data/field flags sometimes denoted with superfluous "flags:" and
sometimes not) and TODOs (such as 2D/3D skins, where there was no format
whatsoever that would have 2D skin support, so the code couldn't get
written).
Now it's finally possible to easily add the remaining missing features,
such as printing camera info.
Similar to the change done in Corrade, see the commit for details:
878624ac36
Wow, this is probably the most backwards-compatibility code I've ever
written. Can't wait until I can drop all that.
It limits the support for CMake 3.12+, but it's much less verbose and I
don't expect people to use ancient CMake versions with IDEs like Xcode
or VS anyway, so this should be fine.
Highly experimental and very assert-y, as it doesn't handle mesh
primitive / attribute type incompatibility or conversion of
loops/strips/fans to indexed meshes yet.
No functional change, just splitting them to two separate headers and
two separate tests. These will eventually become public SceneTools
APIs... once I figure out better naming.
Basically using the same idea as with the discrete version -- having the
second dimension dynamic, together with restricting the implementation to
just Float and Double.
According to the SubdivideRemoveDuplicatesBenchmark, this makes the
implementation slightly slower. I presume this is due to how minmax and
offsets are calculated which is quite cache-inefficient as it goes over
the same memory block multiple times. Added a TODO for later.
Color-coded XY and XYZ axes, cut out of DebugTools::ObjectRender into a
better reusable piece of code. Using the new vertex color functionality
of mesh data.
As with Corrade, this is not exactly backwards compatible, but for
common use case without OBJECT libraries this should not be a problem.
In any case, recreate the build dir and update your copy of all
Find*.cmake modules to avoid weird things happening.
User-facing changes:
* Documentation of all Find*.cmake modules converted to
reStructuredText to follow official CMake guidelines.
* The newfangled way to use the libraries is to link to Magnum::Shaders
instead of adding ${MAGNUM_SHADERS_INCLUDE_DIRS} to include path and
linking to ${MAGNUM_SHADERS_LIBRARIES}.
* The old ${MAGNUM_*_LIBRARIES} are deprecated and now just expand to
Magnum::* target. Use the target directly. These are also enabled
only when building with MAGNUM_BUILD_DEPRECATED.
* The old ${MAGNUM_*_INCLUDE_DIRS} are removed as the Magnum::* targets
cover these too.
Internal changes:
* Global state such as include_directories() was replaced with
target-specific settings.
New in 2.8.9, much cleaner than the previous "solution". Also cleaned up
the surroundings a bit. Fixed cases where PIC was forced independently
of the settings, for plugins the PIC is now also set only when
needed/requested.
Makes it possible to have both debug and release libraries installed. If
both libraries are present when finding the package, proper version is
used based on what configuration is used in depending project.
As we are now using absolute includes, there is no need to prefix
everything with "magnum<Namespace>" etc. All generated configuration
files are renamed to configure.h and their path is included _before_
everything else to avoid accidental collisions.
Everything what was in src/ is now in src/Corrade, everything from
src/Plugins is now in src/MagnumPlugins, everything from external/ is in
src/MagnumExternal. Added new CMakeLists.txt file and updated the other
ones for the moves, no other change was made. If MAGNUM_BUILD_DEPRECATED
is set, everything compiles and installs like previously except for the
plugins, which are now in MagnumPlugins and not in Magnum/Plugins.
