|Summary: Thin type layer for graphic libraries|
When creating graphic libraries you most likely end up dealing with points and rectangles. If you're particularly unlucky, you may end up dealing with affine matrices and 2D transformations. If you're writing a graphic library with 3D transformations, though, you are going to hit the jackpot: 4x4 matrices, projections, transformations, vectors, and quaternions. This library provides types and their relative API; it does not deal with windowing system surfaces, drawing, scene graphs, or input. You're supposed to do that yourself, in your own canvas implementation, which is the whole point of writing the library in the first place.
* Mon Sep 09 2019 Bjørn Lie <email@example.com> - Update to version 1.10.0: + API additions, mostly driven by Gthree: - Add graphene_matrix_decompose(). - Add intersection methods to graphene_ray_t. - graphene_triangle_init_from_float(). - graphene_triangle_get_uv(). + Fix graphene_ray_transform(). + Documentation fixes. * Fri Sep 06 2019 firstname.lastname@example.org - Update to version 1.9.6: + Add radians based initialisers for graphene_euler_t. + Use pragma once for the header inclusion guard. + Remove unused function (#159) + Add multiply(), scale(), and add() operators to graphene_quaternion_t. + Add lerp() operator to all vector types. + Add graphene_plane_transform() + Documentation updates for graphene_ray_t. + Fix graphene_box_get_center() and. graphene_box_get_bounding_sphere() (#165) + Ensure that we detect empty or infinite boxes in the. graphene_box_t API. - Changes from version 1.9.4: + Graphene now uses an ancillary library called µTest for its test suite; this means it's possible to build and run the test suite without necessarily depending on GLib. + the conversion of the Euler angles type to and from matrices and. quaternions has been rewritten from scratch, and should not only be finally correct, but it should also cover more use cases—namely the "proper" Euler angles as well as the Tait–Bryan angles. + the ARM NEON implementation of the SIMD types has been improved, fixed, and tested, so it's not marked as experimental any more. + Require Meson ≥ 0.50.1. + Fix graphene_quaternion_equal() to consider the orientation, not just the component equality. + Fix graphene_quaternion_slerp() to always interpolate along the shortest path. + Re-implement the conversion of graphene_euler_t to and from graphene_matrix_t and graphene_quaternion_t. + Add graphene_rectangle_get_area() + Document restrictions of graphene_rect_round(), and deprecate the function. + Add graphene_rect_round_extents() + Port the test suite from GLib's testing utilities to µTest. + Remove internal floating point comparisons. + Improve the NEON extensions detection code. + Fix comparison operators for graphene_simd4f_t on ARM using the NEON extensions. + Remove the "experimental" compiler warning from the ARM NEON implementation of graphene_simd4f_t. - Changes from version 1.9.2: + Add graphene_rect_scale() method. + Fix warning from Meson by dropping unnecessary argument to. configure_file() + Clean up arguments of pkgconfig.generate() + Add equality operators to graphene_matrix_t. + Add getters for translation components of a graphene_matrix_t. + Use darwin_versions argument instead of rolling our own. + Add GRAPHENE_RECT_INIT_ZERO * Mon Mar 25 2019 Bjørn Lie <email@example.com> - Update to version 1.8.6: + Bug fixes, bug fixes everywhere! Also: documentation changes to clarify what we do behind the veil of the various matrix multiplication functions. Hopefully, this should help people using Graphene especially when it comes to integration with other libraries. + Fix matrix multiplication when the result matrix is also one of the operands. + Fix check when converting a 4x4 matrix into an affine transformation matrix. + Fix interpolation between matrices with a perspective component. + Documentation fixes for matrix/matrix and matrix/vector multiplication operators. - Changes from version 1.8.4: + Mostly a bug fixing release, with an especially glaring bug fix in the point transformation function of graphene_matrix_t that was found thanks to GTK 4. Now the function is covered by the test suite, so it should not regress. + Another major fix is the ensuring that we have a description of the SIMD types through introspection, which means that language bindings can finally know how big every other structure using them is. The SIMD API is still not available through introspection, as it's a pure C convenience. + Require Meson ≥ 0.48.0. + Fix matrix/point transformation. + Build fixes for MSVC. + Introspection fixes for bool. + Fix the InitOnce checks on Windows. + Correctly parse SIMD types for introspection. + Build fixes for the pkg-config file. + Documentation fixes: - Clarify matrix/vector/point multiplication. - Clarify plane description. - Clarify the units for the matrix skew factors. - Document use of graphene-gobject with Meson. * Thu Jun 14 2018 firstname.lastname@example.org - Update to version 1.8.2: + The main change is that we've now disabled SIMD optimisations on 32 bit Intel architectures; there aren't many of those left, and in general compilers have been less than stellar when supporting SIMD types on them. This is especially problematic when it comes to using Graphene types inside other allocated structures, where SIMD alignment rules break system allocators on platforms like Windows. To avoid introducing weird bugs, if you're on 32 bit IA, you're only going to have access to the scalar SIMD implementation. * Fri Feb 23 2018 email@example.com - Update to version 1.8.0: + No new API, this cycle, but it's time to spin a new stable release. + The major news for this release is that we dropped the Autotools build from the repository; Graphene is now built exclusively with Meson. + We've added various fixes to the build on macOS, in order to maintain compatibility with the old Autotools build. + The variables in the pkg-config file that expose the SIMD functionality built inside Graphene have been updated, to ensure that they can be easily consumed by other projects; instead of a single string that needs to be split, we now expose boolean variables for all SIMD implementations. + We've also improved the ability to use Graphene as a Meson sub-project; this allows Meson to check out, build, and depend on Graphene when building complex projects, like GTK. This is really useful inside CI pipelines, as it minimises the amount of separate steps needed when setting up the build. - Update options passed to meson, following upstream changes: gtk_doc=true, gobject_types=true, introspection=true, gcc_vector=true, sse2=true, arm-neon=true, tests=true and benchmarks=true. * Thu Feb 22 2018 firstname.lastname@example.org - Update to version 1.6.2: + Mostly fixes for the Meson build, to ensure it's a bit more idiomatic and conforms to what newer versions of Meson expect from a project. - Do a minor spec clean, use autosetup and license macros. - Stop exporting LANG=C.UTF-8, fixed upstream. - Stop exporting i586 conditional SUSE_ASNEEDED=0, fixed upstream. - Pass explict enable-gtk-doc=true, enable-gobject-types=true, enable-introspection=true, enable-gcc-vector=true, enable-sse2=true and enable-arm-neon=true to meson, ensure we build the features we want. - Following the above, add gtk-doc BuildRequires and package the now built documentation in devel subpackage. - Stop using sed to ensure we are using python3, fixed upstream. - Add fdupes BuildRequires and macro, remove duplicate files. * Wed Nov 29 2017 email@example.com - Switch to python3: + Update the shebang in src/identfilter.py using sed. + Replace --identifier-filter-cmd=python in src/meson.build with - -identifier-filter-cmd=python3 (using sed). + Add python3-base BuildRequires: needed to have the python3 interpreter present. * Wed Aug 09 2017 firstname.lastname@example.org - on i586, disable sse2 for the moment, otherwise the package fails in the testsuite on the "box" test * Sat Mar 04 2017 email@example.com - Update to version 1.6.0: + The Meson dependency has been bumped to 0.37.0. + Added graphene_frustum_equal() method. + Dropped the -Denable-debug option for the Meson build; debugging levels are handled through the --buildtype Meson option; you can use release to disable all debugging code paths when building Graphene. + Graphene now automatically builds binaries for Windows (i686 and x86_64) using Appveyor; you can find the builds attached to the release notes. * Tue Feb 28 2017 firstname.lastname@example.org - Add baselibs.conf: produce libgraphene-1_0-0-32bit, required by gtk4. * Wed Jan 11 2017 email@example.com - Update to version 1.5.4: + For the time being and after requests from distributors, the autotools build environment has been reinstated in Git, though Meson is still the preferred build environment; I still expect to drop the autotools build in the near future. + Graphene now correctly identifies whether the platform has an aligned memory allocator. + Compatibility fixes for printing int64_t to terminal. + Fixed the cross-references to GLib types in the API reference build. + Improve the builtin detection in the Meson build and the build of Graphene under MingW. - Switch to github url, gnome url is currently broken. - Pass export LANG=C.UTF-8, workaround meson issue. - Drop sed call to workaround Mesa issue. * Tue Dec 06 2016 firstname.lastname@example.org - Use meson provided macros to build instead of carrying the long meson command lines. * Mon Nov 28 2016 email@example.com - Trim description outside the main subpackage of interest; reflow summaries. * Thu Nov 24 2016 firstname.lastname@example.org - Initial package, version 1.5.2.
