Too deep nesting, too much typing. Colon cancer. Fully preserving
backwards compatibility, except for the recently added cone/frustum
intersection functions, which were not in master yet.
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.
Some classes are by default constructed zero-filled while other are set
to identity and the only way to to check this is to look into the
documentation. This changes the default constructor of all classes to
take an optional "tag" which acts as documentation about how the type is
constructed. Note that this result in no behavioral changes, just
ability to be more explicit when writing the code. Example:
// These two are equivalent
Quaternion q1;
Quaternion q2{Math::IdentityInit};
// These two are equivalent
Vector4 vec1;
Vector4 vec2{Math::ZeroInit};
Matrix4 a{Math::IdentityInit, 2}; // 2 on diagonal
Matrix4 b{Math::ZeroInit}; // all zero
This functionality was already present in some ugly form in Matrix,
Matrix3 and Matrix4 classes. It was long and ugly to write, so it is
now generalized into the new Math::IdentityInit and Math::ZeroInit tags,
the original Matrix::IdentityType, Matrix::Identity, Matrix::ZeroType
and Matrix::Zero are deprecated and will be removed in the future
release.
Math::Matrix<7, Int> m{Math::Matrix<7, Int>::Identity}; // before
Math::Matrix<7, Int> m{Math::IdentityInit}; // now
Forward declarations of templated types don't have named template
parameters and thus Doxygen (sometimes) used these for documentation. It
then looked like this:
Magnum::Math::RectangularMatrix<std::size_t, std::size_t, class>
which isn't helpful at all. After the change it looks like this (much
better):
Magnum::Math::RectangularMatrix<cols, rows, T>
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.
Much like Shape::collides() is equivalent to the more low-level
collision detection using operator%, the Shape::collision() returns
collision details similarly to operator/. Currently only Sphere/Sphere
and Sphere/Point collision is done, thus the dispatch is nearly empty.
Currently all the functions taking vectors of objects (e.g. setClean(),
transformations() and transformationMatrices()) were taking pointers,
which lead to additional (and often forgotten) nullptr checks. The
internals are now much more clean, as the parts where we are dealing
with pointers are reduced to bare minimum.
Also renamed private Object::setClean() function to
Object::setCleanInternal() to avoid overload clash with the public one.
The old way is now an nullptr-checked alias to the new one, is marked
as deprecated and will be removed in some future release.
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.
The only places where they aren't absolute are:
- when header is included from corresponding source file
- when including headers which are not part of final installation (e.g.
test-specific configuration, headers from Implementation/)
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.
