Followup to previous commit -- links to opengl.org are now redirected to
khronos.org and the extension links have the same format for both GL and
GLES. That allows me to remove some of the Doxygen aliases and use just
a single set of the functions for both GL and GLES.
It was just RGB before. In order to avoid breaking current code, the
attribute now requires explicit specification of number of components.
If building with deprecated APIs enabled, there is an additional
deprecated constructor that defaults to RGB so the current code should
keep working as-is.
There will be numerous additions to this one so it made sense to make it
a static library instead of a header-only library. That also allows
CMake users to just link to Magnum::OpenGLTester instead of going
through the pain of a huge branching in order to find a correct
windowless application just to run their tests. It could have been done
even without the static library using a INTERFACE target, but that
wouldn't work on CMake < 3.0 (which, unfortunately, quite a few people
are still stuck with).
Unfortunately it's already heavily used elsewhere so I had to go through
the pain of deprecating the old implementation. The old implementation
was header-only so it can't be just typedef'd to the new one as there
would be linker failures. So the old header is just kept as it was, with
only the macros reduced.
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.
103% of use cases use the returned value directly without checking, so
we might as well do the check ourselves. Added new function hasCurrent()
and added deprecated backward-compatibility conversion and -> operators.
Wow, that creeped to a lot of places.
Last dinosaur from the pointer age.
Also probably fixed a few issues when compiling the shader on older GLSL
and GLSL ES (floating point literal suffixed, missing precision qualifiers).
And less crazy preprocessor.
Apart from different include (<Magnum/Math/Color.h> instead of
<Magnum/Color.h>) there shouldn't be any visible change to the user. The
BasicColor3 and BasicColor4 classes are now Math::Color3 and
Math::Color4. The Color3, Color4, Color3ub and Color4ub typedefs in
Magnum namespace stayed the same.
BasicColor3 and BasicColor4 is now an alias to Math::Color3 and
Math::Color4, is marked as deprecated and will be removed in future
release. The same goes for the <Magnum/Color.h> include, which now just
includes the <Magnum/Math/Color.h> header.
Please note that in ES3 there is a behavioral change -- geometry shader
is no longer explicitly disabled, but it is enabled by default and you
have to disable it if you don't have the required extension or don't
want to use it.
I wanted to preserve the parameter-less constructor of tests, but WINAPI
requires fairly ugly entagled set of functions, passing HWND around,
which required storing it in a global var and hoping it is properly
initialized when querying it for it to be passed to application
constructor.
When this was done, it was now fairly easy to support passing also
argv/argc to application constructor, which in the future will enable
selective disabling of extensions for even better test coverage.
This however needed slightly different main() function and thus we now
have MAGNUM_GL_TEST_MAIN() instead of CORRADE_TEST_MAIN(). Using the
latter will result in an assert inside std::optional.
Each class/function that needs to access the resources first checks
whether the group exists and the group is registered if not. Thus there
is now no difference and annoying special cases when using static build.
Each shader now has sample image, example mesh configuration and example
rendering setup. Also properly documented all attribute types and made
introductory chapter for whole Shaders namespace.
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>
No backward compatibility issues should exist, as the class is in most
(if not all) cases used with unscoped name:
class MyShader: public AbstractShaderProgram {
public:
typedef Attribute<0, Vector3> Position;
// ...
};
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.
