AbstractMaterialData is now just a typedef to MaterialData, with all
existing public APIs moved to (and marked as deprecated, if they don't
make sense anymore). The new class doesn't have a virtual destructor as
that's not the desired use anymore -- and AbstractImporter::material()
APIs will be returning an Optional instead of a Pointer, which means any
potential subclasses will be sliced away.
PhongMaterialData is reimplemented using the new key/value store,
with no own members anymore -- thus having the same size as
MaterialData, and safe to be casted from it to access the helper APIs.
Better since it has the same prefix as other texture-related attributes,
such as *TextureMatrix(). Not using *TextureCoordinateSet() because
that's overly long, *TextureSet() is OTOH confusing (and especially so
if we'd introduce *TextureLayer()).
Those would be unfortunately very hard to preserve when switching to the
new MaterialData. These accessors mattered mostly only when populating
the instance (i.e., in importer plugins) so such breakage shouldn't be
too much of a problem for regular users.
It now supports both color+texture (instead of just one or the other)
which made it much simpler to use (and implement as well), also can
reference normal maps and specify texture coordinate transformation now.
The old APIs are depecated, but no tests or other code is updated yet in
order to ensure everything continues to work as before.
Bloaty says it saved 10 kB in Debug build of MagnumGL:
VM SIZE FILE SIZE
-------------- --------------
[ = ] 0 .debug_info +1.59Ki +0.0%
+0.4% +1.50Ki .text +1.50Ki +0.4%
[ = ] 0 .debug_str +409 +0.0%
[ = ] 0 .debug_line +276 +0.1%
[ = ] 0 .debug_abbrev +20 +0.0%
-28.6% -2 [LOAD [RX]] -2 -28.6%
[ = ] 0 [Unmapped] -4.28Ki -41.0%
-22.7% -9.23Ki .rodata -9.23Ki -22.7%
-0.8% -7.73Ki TOTAL -9.73Ki -0.1%
And 4 kB in Release:
VM SIZE FILE SIZE
-------------- --------------
+1.1% +3.44Ki .text +3.44Ki +1.1%
+1.7% +1.39Ki .eh_frame +1.39Ki +1.7%
[ = ] 0 [Unmapped] +656 +51%
-25.5% -9.47Ki .rodata -9.47Ki -25.5%
-0.7% -4.64Ki TOTAL -4.00Ki -0.4%
That's not negative, so I guess that's good. This change is of course
more significant in the context of a minimal WebGL build, where the exe
can be as little as 50 kB -- there 4 kB is almost 10% of the size.
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.
* They are now deinlined into source files, as most of the classes have
either heavy members (std::vector) or virtual methods.
* All of them are explicit now (that should be already done, don't know
why not).
* Passing huge classes by value and using move constructors to avoid
unnecessary copying.
Functionality present in Object is now split into three main components:
* Object itself, handling parent/children relationships
* Transformation implementation and interfaces for common functionality
* Object features, providing transformation caching and base for
cameras, collision shapes, rigid bodies etc.
Some functionality depending on former implementation is temporarily
disabled and will be reworked later.
SizeTraits class provides suitable types for given data size at compile
time, SizeBasedCall can call suitable templated overload based on given
data size at runtime.
Also added meta classes Pow and Log for computing powers and logarithms
at compile time, usable mainly in conjunction with SizeTraits. Their
implementation is checked at compile-time using static_cast().
