Matrix rotation fails for Rotations not dividable by 90°
Matrix rotation is not calculated correctly when used on an existing matrix. The init method is fine.
This is due to a bug in the matrix multiplication.
The matrix rotation test fails when 10° is used.

matrix_unproject_point3d requires an inverted modelview matrix
To fully invert from screen space to model space, the modelview matrix passed to graphene_matrix_unproject_point3d needs to be inverted. I believe that was attempted in e0c4e4c but reverted because it's a behaviour change by e0c4e4c. Instead the documentation should be updated to mention that the caller needs to pass the inverted modelview matrix.
Pacman doesn't seem to work...?
Hi, I followed your instructions for building on Windows, but no matter what I do, Pacman keeps firing timeouts at me. I don't have issues with my internet connection, as evidenced by the fact that I'm posting this question.
$ pacman -Sy
:: Synchronising package databases...
error: failed retrieving file 'mingw32.db' from 148.251.42.38 : Operation timed out after 0 milliseconds with 0 out of 0 bytes received
mingw32 28.9 KiB 46.3K/s 00:04 [#######-------------------------------------------------] 13%
This happens with every file it tries to download. Is there any step I should have followed which was not listed in your instructions?
add vector/scalar multiplication operator
internally, it should be something in the form of:
res = graphene_simd4f_mul (vec, graphene_simd4f_splat (scalar));
but we need the graphene_vec[234]_t wrappers around it.
the name could be graphene_vec[234]_scale().
Vector subtract and divide: precise order of operation (a-b, a/b)
For graphene_vec__subtract() and graphene_vec__divide(), even if it's obvious it should be documented the order of the parameters in the operation, since subtract and divide are not commutative.
So, I guess the order is a-b and a/b.
Inspiration with blend2d - highly optimized and CPU accelerated 2D library
There is a highly advanced project Blend2D dealing with graphical operations being computed on CPU, but focused on 2D. It might be a good source of inspiration or even source code (though it's C++) as it has no dependencies (not even standard library) and is basically the fastest possible library for 2D graphical operations. Graphene does not necessarily provide these operations, but rather a base for them, so this is just a pointer in case it should get extended or a new thin library on top of Graphene should get created.
Blend2D is also based on the awesome AsmJIT library from the same author.
Fix graphene_triangle_get_barycoords() for a point outside the triangle plane
graphene_triangle_get_barycoords() is based on this algo. From the description on that page:
With that in mind we can now describe any point on the plane as
P = A + u * (C - A) + v * (B - A)
-> "on the plane".
From the book that I read, there are three different algorithms described, with:
Although it is straightforward to solve Equation (2.32) algebraically, it is often fruitful to compute a direct geometric solution.
The algebraically equation being roughly the same as implemented in graphene currently.
One geometric solution is to compute the signed areas of the sub-triangles: A_a being the subtriangle PBC, A_b the subtriangle APC and A_c the subtriangle ABP, and A the area of the full triangle ABC. A_a + A_b + A_c = A if the point is in the same plane as the triangle. And the barycentric coordinates are A_b/A and A_c/A. Looks like a simple solution, at least on paper. (note that I've written this paragraph a bit quickly, it can contain some mistakes such as the order of the subtriangles vectors, since it matters for a signed area).
Error no such file or directory graphene-config.h
HI
I'm trying to use graphene for calculations in OpenGL program
I opened the NetBeans and i have typed #include<graphene-1.0/graphene.h>
then build
the following error appeared
/usr/local/include/graphene-1.0/graphene-types.h:31:29: fatal error: graphene-config.h: No such file or directory
I tried to add option to the linker like -lgraphene or -lgraphene-1.0 and still the error appears
could you help me please
thanks in advance

graphene_quaternion_to_angles: which convention is used?
Experienced behavior
quat = graphene_quaternion_init(quat, 0.7071, 0.7071, 0, 0 );
graphene_quaternion_to_angles (quat, &yaw, &pitch, &chroll);
yields
yaw = 180
pitch = 0
roll = -90
Expected behaviour
If compared against https://github.com/matthew-brett/transforms3d

one finds no triple with one of the angles being -90 and the other 180 degrees.
q[0] corresponts to graphene's q.w .
I am pretty sure about https://github.com/matthew-brett/transforms3d as I checked quat2euler(q,axes='rzyx') case before with quaternion and Yaw-Pitch-Roll output of my gyro.

No aligned malloc implementation on MinGW
When building on Windows with MinGW, there's no available aligned malloc implementation:

meson:

This means that alloc_align() in src/bench/matrix.c ends up returning an uninitialized pointer. The implementation needs to be like this to actually show the bug at compile-time:

I noticed this because of this warning:

Maybe graphene should be built with werror=true in meson.build:project() so that -Werror is enabled, or perhaps that option can be enabled with a version check inside meson.build.
segfault in graphene_matrix_interpolate() with clang and scalar SIMD4f

the issue goes away when compiling graphene with -O0; any other optimization causes a segmentation fault.
vapigen produces invalid code
This is either a bug in vapigen or in graphene's GIRs.
I ran vapigen on the graphene gir and all the res arguments had out unowned modifiers on them. This causes vala to attempt to double-redirect for them, which is wrong.
use degrees instead of radians in matrix rotation
no need to make things more complicated than they need to be.
the underlying graphene_simd4x4f_rotation() function can keep using radians, but the convenience API for graphene_matrix_t needs to be converted to degrees.
graphene_rect_union(): schema and implementation mismatch
I see that you've added schemas, that's nice.
But for graphene_rect_union(), the implementation doesn't do what the schema shows:
res->origin.x = MIN (ra.origin.x, rb.origin.x);
res->origin.y = MIN (ra.origin.y, rb.origin.y);
res->size.width = MAX (ra.size.width, rb.size.width);
res->size.height = MAX (ra.size.height, rb.size.height);
In other words, the schema shows the bounding rectangle, but the union() function does something else. That's why I said in the other bug that rectangle union was a strange operation to me.
Allocation problems in Python
What are graphene's plans for gobject introspection? Will it be still supported, despite the "de-glib-ify" branch?
I would like to use graphene in Pitivi for OpenGL, as I suppose many other Python users would find very useful.
These issues need likely to be reported to gobject-introspection or python-gobject, I will collect them here to have an overview though.

generate introspection data
even if Graphene is not strictly speaking a GObject library, we should generate introspection data from the GTypes we expose.
right now, we depend on https://bugzilla.gnome.org/show_bug.cgi?id=706898 to land inside the gobject introspection scanner, otherwise it'll croak on our type naming convention.
after that bit lands, the generation is pretty straightforward. see the introspection branch.

Is it possible to use radian instead of degree
Hello,
it seems to me that it should be much efficient to use radian instread of degree at least internally.
so the rotation to quaternion convesion should avoir degree -> radian -> degree concersion all around
Cheers

Mac OS X build error due to -Bsymbolic-functions
Experienced behavior
On Mac OS X El Capitan, the build process fails while generating libgraphene-1.0.dylib due to an unrecognized linker flag -Bsymbolic-functions, which is apparently not supported by clang.
Full output:
clang -o src/libgraphene-1.0.dylib 'src/graphene-1.0@sha/graphene-alloc.c.o' 'src/graphene-1.0@sha/graphene-box.c.o' 'src/graphene-1.0@sha/graphene-euler.c.o' 'src/graphene-1.0@sha/graphene-frustum.c.o' 'src/graphene-1.0@sha/graphene-matrix.c.o' 'src/graphene-1.0@sha/graphene-plane.c.o' 'src/graphene-1.0@sha/graphene-point.c.o' 'src/graphene-1.0@sha/graphene-point3d.c.o' 'src/graphene-1.0@sha/graphene-quad.c.o' 'src/graphene-1.0@sha/graphene-quaternion.c.o' 'src/graphene-1.0@sha/graphene-ray.c.o' 'src/graphene-1.0@sha/graphene-rect.c.o' 'src/graphene-1.0@sha/graphene-size.c.o' 'src/graphene-1.0@sha/graphene-sphere.c.o' 'src/graphene-1.0@sha/graphene-triangle.c.o' 'src/graphene-1.0@sha/graphene-vectors.c.o' 'src/graphene-1.0@sha/graphene-gobject.c.o' 'src/graphene-1.0@sha/graphene-simd4f.c.o' 'src/graphene-1.0@sha/graphene-simd4x4f.c.o' '-shared' '-install_name' '/private/tmp/graphene-20161228-17028-1bw9frc/graphene-1.5.2/build/src/libgraphene-1.0.dylib' '-pthread' '-Wl,-Bsymbolic-functions' '-lm' '-L/usr/local/Cellar/glib/2.50.2/lib' '-L/usr/local/opt/gettext/lib' '-lgobject-2.0' '-lglib-2.0' '-lintl' '-Wl,-rpath,/private/tmp/graphene-20161228-17028-1bw9frc/graphene-1.5.2/build/src'

GObject support: make the CamelCase types available in C
There is no typedefs in graphene-gobject.h, so the CamelCase types are not available in C, just for languages like Python, JS, etc. But when reading the documentation, I thought that the CamelCase types were also available in C.
I have a patch almost ready for this, the gtk-doc comments just need to be written and it should work fine.
When using only GLib-based libraries in an application, it's nice to have all types in CameCase, it makes the code consistent.

Installing on Windows
After a bit of research and some help from the creator, I finally got it working on Windows
Documenting it so people don't suffer as much as I did...
1- Install MSYS2
2- cd
3- pacman -Sy
4- pacman -S pkg-config
5- pacman -S libtool
6- pacman -S automake
7- pacman -S gtk-doc
8- pacman -S autoconf
9- ./autogen.sh
And that's pretty much it...
Does not build on Android ARM
It unconditionally uses NEON it seems. Not all Android devices have NEON so we need to compile it in conditionally and detect at runtime.

Problem overriding libexecdir
For Debian, we want the installed tests to end up in /usr/lib/installed-tests/graphene-1.0/
So I used the meson flag -Dlibexecdir=/usr/lib but the tests were still installed to /usr/libexec/
More meson flags?
I am looking at converting Ubuntu's graphene package to meson.
There are 3 configure flags I use:
--enable-gtk-doc (not needed?)
--disable-sse2 (on non-64bit x86)
--disable-arm-neon (on armhf because at least Ubuntu's armhf builder doesn't support neon)
Tests fail on Ubuntu's i386
Experienced behavior
graphene 1.5.4 built successfully on Ubuntu 17.04 Alpha amd64 in the GNOME3 Staging PPA but the build tests failed on i386.
I used autotools for building. Here's my packaging.
Here's a few of the test failures:

ERROR: euler - exited with status 139 (terminated by signal 11?)
Explain a bit more the underlying maths?
I'm finally learning computer graphics with the Fundamentals of Computer Graphics book, by Shirley and Marshner. In parallel I'm looking at the graphene API and implementation.
I wonder if it makes sense to better explain the underlying maths in the graphene API. At least just a summary or examples.
For example for graphene_point_interpolate(), it could be explained that for a factor of 0 the result is the point a, for a factor of 1 it's the point b and 0.5 (for example) is at the middle of the line that goes through a and b.
Or is it considered too well-known to bother explaining that kind of thing?
Missing .test files for installed tests
Ubuntu (and Debian)'s autopkgtest infrastructure could probably automatically run the graphene installed tests using gnome-desktop-testing-runner if graphene provided .test files.

ninja: build stopped: subcommand failed.
Expected behavior
Ninja completes the build so I can make you a nice mingw-w64-graphene-git package to allow the new GTK3 dependencies to be built on Windows.
Steps to reproduce
These also form updated build instructions for MSYS2.
From an MSYS2 environment:
-
Build mingw-w64-meson withNow just install them:makepkg-mingw -sf(packages are not yet available in the repository because @Alexpux has been busy)pacman -S mingw-w64-i686-meson mingw-w64-x86_64-meson -
Install the resultant packages:pacman -U *.pkg.tar.xz -
Install ninja from the repository:Now pulled in as a dependency.pacman -S mingw-w64-{x86_64,i686}-ninja -
Install graphene's documented dependencies:
pacman -Syyuu # repeat as needed, closing the terminal when it tells you pacman -S automake autoconf libtool pkg-config gtk-doc pacman -S glib2 # why not native (mingw-w64-{x86_64,i686}) ? -
From a MINGW64 or a MINGW32 shell,
cd /usr/src/ git clone git://github.com/ebassi/graphene cd graphene/ mkdir _build && cd _build meson.py .. # note the different name on these platforms ninja
At which point it fails with the error above.
Operating system in use
Windows 7 Professional N (on Virtualbox on Debian)
SIMD implementation in use
Not a clue, I only care about getting graphene built sensibly so I can fix wacom stylus tilt in GTK master.
Plane: "normal vector pointing towards the origin" is confusing
As far as I understand, the normal vector of the plane can point in the reverse order than towards the origin.
In graphene_plane_init(), 'constant' is the negative distance. So should the value of 'constant' be positive or negative? Are both positive and negative allowed?
What does graphene_plane_normalize() do? I think it should be documented in the class description. I guess a normalized plane is when the normal vector really points to the origin.
For graphene_plane_negate(), "Negates the normal vector and constant" -> if both values are negated, the result is the same plane, no? Or I've misunderstood something, and it's related to the above comments.

column major
Hi
Is your matrix math column or row major ordering? I was wrangling with sony's vectormath library and while the math is good the api is really terrible [in my opinion]. You seem to have a reasonable api with neon and sse support. Do your matrices work with column major or row major?
Also do you provide a cmake build?
add matrix/vec3 transformation
we need a public facing version of graphene_simd4x4f_point3_mul(), likely using graphene_point3d_t.
we already have a graphene_matrix_transform_vec3(), which uses graphene_simd4x4f_vec3_mul(), so we cannot add a graphene_matrix_transform_vec3() using graphene_vec3_t. we could call it graphene_matrix_multiply_vec3(), but it gets slightly weird.
Failing tests for armhf
Experienced behavior
The build tests for graphene 1.5.4 are failing on the armhf architecture.
https://launchpad.net/ubuntu/+source/graphene/1.5.4-0ubuntu2
Operating system in use
Ubuntu 17.04 Alpha
SIMD implementation in use
ARM Neon
Workaround
Use --disable-arm-neon when building for armhf
The builds works on arm64 because it does not use the ARM Neon instructions there.
graphene: FAILED: src/Graphene-1.0.gir
Experienced behavior
I was trying to build gtk 3.89.2 and noticed that I didn't have the graphene-gobject library installed after rebuilding graphene 1.5.2 with your fix from #91. By the way, this library was not checked for during gtk+'s configure invocation, it only showed up as compile-time error when the graphene-gobject headers were not found...
I retried then after passing the required options to meson but ended up with the following errors:
[64/65] 'Generating Graphene-1.0.gir with a custom command.'

No idea sorry.
I noticed that your Travis-CI configuration explicitly excludes the gobject-introspection build: is there are particular reason for this? Also, would it be a good idea to add a Travis-CI Mac OS X build to the yaml file? I could add a PR for this.
Thanks for looking into this and best wishes for 2017!
X86 32bits builds fails
We observe build failures on X86 32 bits platform. The problem is that to use SSE2 intrinsic, you need to enable SSE2 in compiler flags. Though, you don't want to do this globally, as we want to choose the right routine at run-time base on CPU flags. The solution sens in pixman, is to split the SSE2 code into it's own .c and set flags for the compilation of that object only.
https://ci.gstreamer.net/view/All/job/cerbero-cross-mingw32/1755/console
Note it's very similar to issue #21 though it's a wider issue, as it affect iOS and Android builds too.
Are there any prebuilt binary packages?
I'm having a lot of trouble getting through a successful build (see my other issue). Are you aware of any prebuilt binary packages (i.e. libs+headers I can compile and link against) available anywhere for download? I'm developing on Windows but also wish to offer builds of my application for OSX and Linux. Support for ARM and others is not important to me at this stage.
Allow Graphene to be Built With Visual Studio
Hi,
As Graphene is going to be a dependency of GDK (or so) in the near future, I thought it might be good to make the code buildable and usable with Visual Studio, eventually coming up with Projects or NMake Makefiles to build the library, which I spent the last few days figuring out, with SSE intrinistics support for x64 builds.

Expected behavior
Test should pass.
Steps to reproduce
Build with GCC 4.7.3, i686-w64-mingw32-gcc and run ninja test.
Operating system in use
Windows 8.1 64-bit on x86-64
SIMD implementation in use
SSE2 intrinsics weren't found and the GCC version is too old for vectors intrinsics.
Remove hard dependency on GLib
even if we're a C library, we don't use GLib very much: little to no data types; no API except in the test and benchmark suites; just a handful of macros that can be fairly easily replaced with our own.
ideally, a de-GLib-ified Graphene can be used as a dependency on constrained devices, or devices where getting GLib running is not trivial.
the current work exists in the de-glib-ification branch. it should not go out of sync easily: after all, it's just a search and replace job plus some build environment glue to disable the various bits and pieces.
the only GLib data type we currently use, and expose in the API, is gboolean, and we can effectively replace it with stdbool.h and bool. the only downside is that we'd drop compatibility with non-C99 compilers (hi, I'm looking at you MSVC). I'm literally failing to conjure enough care, but that's the main reason why I just didn't go ahead and merged this work.
we clearly want to keep the test and benchmark suites, and this means using GLib; I don't want to re-implement GTest.
we also want to provide GObject types for GObject-based libraries depending on Graphene, but that's already optional and can be disabled.
