You can add this to readme.md,I think my commit are too much ,and it is not clean , so can you add about it?
a page about how to build with msys2: https://blog.csdn.net/weixin_43539313/article/details/122094269
(This page is written in Chinese)

1.0f / 30.0f
should be changed to
1.0f / frameCount

Did you use the infomation here.https://mikumikudance.fandom.com/wiki/MMD:Polygon_Model_Data
I want to know where to find the pmd pmx file format detailes.
As a un opensource software miku miku dance. I don't know how 樋口优 design the bin format.
I try to use python to parse pmd file.
But meet a problem at here

I see your code. I did not find the data about index section.
So pmd file do not have this section?

I have complete use python to parse vmd file .
And I will try to parse model file .

The log panel shows that load texture(.jpg) file success, but the model is still white model.

This project is perfect, and I am trying to port it to kotlin (without cpp), and I stucked on animation and physics calculation, but the base loader is finished and available in Minecraft
mmdbase (loader lib): https://github.com/PrimogemStudio/mmdbase
Minecraft interface (framework): https://github.com/PrimogemStudio/Adavanced-Framework
Thanks for implementation this on kotlin! (I hate cpp of its poor crossplatform and new features after C++ 11, I have to build libs for every platform and operating system)

why not yaw-pitch-roll?

Hi, I'm trying importing saba to my own OpenGL project. I followed the instruction in wiki, and the code in simple_mmd_viewer_glfw.cpp. But I could only get a twisted model, which I had no idea why.

Here is my model class: pastebin
The rest program is like:

mmdModel = new MmdModel("pmx", "vmd");
mmdModel->init();
while (1) {
    mmdModel->draw(mmdShader);
    mmdModel->idle(deltaTime);
}

I also noticed that changing m_mmdModel->GetUpdatePositions() to m_mmdModel->GetPositions() would make the model renderred properly but with no animation.

Any help will be appreciated. And thanks for developing this fantastic repo since assimp only support poor pmx feature.

Where is your entry definition of saba?
Thanks.

At Saba/Model/MMD/PMXModel.cpp line 739:

boneMorphElem.m_rotate = glm::quat_cast(rot1);

the internal order of the quaternion seems inconsistent with that returned from node->GetRotate(), so it goes wrong at PMXModel.cpp line 1268

glm::quat q = glm::slerp(node->GetRotate(), boneMorph.m_rotate, weight);

when interpolating the quaternion.
I tried two versions of glm, the one in this repo and the newest version, and they both have this problem, and the order of the quaternions is not even the same between the two versions.

I'm converting your code from C++ to Kotlin, but i see this in your code.

 limitMin.x = -ikLink.m_limitMax.x; 
 limitMin.y = -ikLink.m_limitMax.y; 
 limitMin.z = ikLink.m_limitMin.z; 

for this part https://github.com/benikabocha/saba#required-libraries
I install OpenGL/Bullet Physics/GLFW with vcpkg:

vcpkg install glfw3
vcpkg install OpenGL
vcpkg install bullet3

and execute the follow
cmake .. -G "Visual Studio 17 2022" -DCMAKE_TOOLCHAIN_FILE=C:/dev/vcpkg/scripts/buildsystems/vcpkg.cmake

get the error:

How can I pass vcpkg installed libraries to cmake Correctly ?

Also, does the cmake command here need to add two ., because there is no CMakeLists.txt file in mkdir/cd build , an error will be reported.

For some models, Saba segfaults when doing PMXModel::InitializeAnimation(). m_ikTarget isn't initialized, and program finally crashes at MMDIkSolver::SolveCore(). Same behavior in saba_view, examples and direct library usage.
I could post an example model, which I try to load.

I'm impressed by your awesome code.
I found Bullet which is installed by brew has crash problem in high Sierra and Mojave.
This is the solution from googling. I hope this can be a help for updating your installation document.

1. Comment out SIMD related definition in btScalar.h
   https://pybullet.org/Bullet/phpBB3/viewtopic.php?t=9443
2. Build Bullet without double precision. For this modify build_cmake_pybuild_double.sh as following.
   cmake -DBUILD_PYBULLET=ON -DBUILD_PYBULLET_NUMPY=ON -DUSE_DOUBLE_PRECISION=OFF -DBT_USE_EGL=ON -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="your installation path" ..
3. After build, run "make install" in the build_cmake folder.
4. Link built Bullet with Saba viwer.

If I want to save and download the rendered video, what should I do?

Not a Transparent Window but run fine.I don't know what's happen!

Is the model in saba editable?
Thanks for your answers.

はじめまして
こちら確認させていただきましたところReame.jp.MEでの
cmake -G "Visual Studio 14 2015 Win64" ^
-D SABA_BULLET_ROOT=<bullet のインストールディレクトリ> ^
-D SABA_GLFW_ROOT=<GLFW のインストールディレクトリ> ^
..

を実行したところ
Does not match the generator used previously: Visual Studio 15 2017 Win64
がでてしまい2017でしか動かないようですが
こちら2015ではできないのでしょうか？

or compile saba on window with msys2.
I want to use saba as a lib support for godot engine to load mmd model files

i try to modify vmdAnimation.cpp to check if the animation has ended,and then replay it...but the key frame at the last index seems not the end of the animation.....can you give me a example or ....release a new version.thanks. : - )

how to export the pmx and vmd to fbx?

When building with Xcode, directories such as Debug and Release are created one level below and executable files are generated there. Currently, the resource directory is not copied to each directory, so the startup fails at the point of font loading.

thanks for this wonderful lib. How to make Saba able to render animation driven by vmd animation keyframes?

Does the lib glfw bullet means include file and libs(.dll,.lib),or just source code ,then cmake will call cl.exe to compile?
I meet some problem on github actions.(I have succcessfully compiled Godot Game Engine and suika2(Visual Novel)Engine with github actions.)
Also tries use linux vm (on actions)to compile saba with mingw/mingw-w64,I installed " mingw-w64-dev ",but it says there's no <windows.h>.

新しい更新が入ったと思って最新をpullさせていただきましたが
simple_mmd_viewer_dx11にて以下のエラーが出ております
エラー C2275 'IDXGIDevice1': この型は演算子として使用できません simple_mmd_viewer_dx11 D:\prog\pmx\saba-master\example\simple_mmd_viewer_dx11.cpp 1397

どうやらstructとして判別しているらしく->が使い得ないみたいです
hr = m_device->QueryInterface(&dxgi);
Cmakeでは前回と同様にVs2015と2017を使っていますが両バージョンにて同様のエラーで出ております
なにか設定するものはありますでしょうか？
ご教授お願いいたします

I found that such bones is not supported, but widely used.
I take quick look and found implementation of this bones here:

まず、sabaライブラリを使って、自分のMMDデスクトップマスコットプログラムを作ってみたのですが、窓の背景と枠を透明にしてみたら、モデルがalphaを持っている限り!=0とすると,2つの問題が存在する：
1.もし,外層が半透明であれば,中にまったく不透明なものがあっても,デスクトップの背景の内容が透過してしまう。

2.背景が薄いとモデルが明るさを増しておかしくなる。黒一色の背景でのみ正常に表示される。

sabaのライブラリの面で相応の修正をして、この問題を解決できますか?ありがとうございます。問題の具体的な表現は次の2つのスクリーンショットです：

I found that some function parameters are different from the MinGW header file type.
