Learn Vulkan. Advanced examples of Vulkan, QT, CUDA, OpenCV for Linux, Windows, Android.

LearnVulkan

😀This project is mainly faced to GUI engineering applications and advanced backend computing, such as X11, Qt, ffmpeg, OpenCV, CUDA and so on. Combining Vulkan with engineering applications, not a pure demo.

Planned Application Areas:

1. Imaging Proceessing of Vulkan😁
2. Vulkan on Qt 🤣
3. Vulkan on XWindow 😃
4. Vulkan with CUDA😅
5. Vulkan offscreen rendering with ffmpeg😆
6. Vulkan with physical engine😆
   
   

What is more than SaschaWillems's Project

This project is partly based on SaschaWillems's Project, add some functions of cross-platform window operation , deleted MFC code of the main function(WinMain), and provides a unified interface api for cross-platform.
For Android, use the jni and android java surface activity instead of native glue. You can use the java widgets of Android Sdk on the Vulkan Surface. The front-end UI uses MVVM framework to better meet the application requirements.
Use sharelib (libvulkanbase.so, libvulkan_basicengine.so) instead of static lib.

• Sharelib : ✅
• Supported System : Linux & Windows & Android
• PNG and JPEG Texture Load : ✅ (Auto turn to RGBA8 format)
• Volume Texture3d Load : ⭕ (Will support nii and raw data)
• Auto Mipmap-Gen : ✅
• Qt-binding(vulkan widget) : ✅
• Relative path and absolute path management for IDE : ✅
• Basic object template(Ball & Square & Cube and so on) : ⭕
• Android Vulkan Surface Activity (Java) : ✅
  For examples of cross-platform api:

int main(int argc,char** argv){
    bool debug=false;
    StaticTriangle* pVulkan=new StaticTriangle(debug);
    pVulkan->initVulkan();
    pVulkan->initWindow();
    pVulkan->prepare();
    pVulkan->renderLoop();
    delete pVulkan;
    return 1;
}

Simple object-oriented package reduces the amount of code and makes it easier to use and understand Vulkan.

    m_sky = VkObject::New<VulkanCube>(m_context);
    m_sky->prepare();

    m_skyShader = VkObject::New<VulkanVertFragShader>(m_context);
    m_skyShader->setShaderObjPath("shaders/Skybox/skybox.so.vert",
                                   "shaders/Skybox/skybox.so.frag");
    m_skyShader->setCullFlag(VK_CULL_MODE_FRONT_BIT);
    m_skyShader->prepare();

    std::vector<std::string> skyImages = {
            "textures/skybox/back.jpg",
            "textures/skybox/front.jpg",
            "textures/skybox/top.jpg",
            "textures/skybox/bottom.jpg",
            "textures/skybox/right.jpg",
            "textures/skybox/left.jpg",
    };
    m_skyTexture = VkObject::New<VulkanTextureCubeMap>(m_context);
    m_skyTexture->loadFromFile(skyImages, VK_FORMAT_R8G8B8A8_UNORM);

The libvulkan_basicengine.so also integrates 'stb_image' from https://github.com/JoeyDeVries/LearnOpenGL, supporting jpg and png image loading, and you don't need to generate ktx images for Vulkan Texture now. See 'vulkan_basicengine_texture.h'.

Finally, welcome to clone or fork my project, remember to star if you consider my project is quite good.

Requirements

Supported System:

Now: Linux(Mainly) Windows(Partly) Android(Partly) Planned supported: Mac(I have successfully installed black Apple) IOS

Libraries and Tools

CMake: 3.14+ is recommended Vulkan: 1.1.121+ Glm: 0.9.9+ Xcb & Xlib (Linux needs) GLFW3
OpenCV: 4.0+ (Some projects need) CUDA: 10.0+ (Some projects need) Qt: 5.12+ (Some projects need)

C/C++ Compiler

GCC 7+ using -std=c++17 MSVC 2017

Download

git clone https://github.com/engineer1109/LearnVulkan.git --depth=1

'--depth=1' will reduce the download size of repo.

Compile & BUILD

For Linux/UNIX

Compile

    cmake ..
    make
    make install

The programs will be installed in the {PROJECT_DIR}/bin .

For Qt

    cmake .. -DBUILD_QtExamples=ON

For Windows

Compile

    cmake -G "Visual Studio 15 2017 Win64" -T host=x64 ..
    cmake --build . --config Release
    cmake --build . --config Release --target INSTALL

The programs will be installed in the {PROJECT_DIR}/Release .

learnvulkan's Issues

MacOS 的支持

希望也能补充MAC的项目配置，mac或者黑苹果都可以~~

Forgot __declspec(dllexport)

I found some code of this project is lacking __declspec(dllexport).
Use static lib is ok.
Please check.

app/shaders 目录下的shader文件加密了，无法打开

您好！
我是vulkan 初学者，非常感谢您的分享，在学习的过程中，发现app/shaders目录下的shader 文件加密了，无法阅读，请问下需要用什么工具打开。

crash when use QtVulkan

crash code:
(file :VulkanBase.cxx, project:QtVulkanSceneDemo)

void VulkanBase::draw() {
    if (m_stop or m_pause) return;
    m_signalFrame = false;
    prepareFrame();

    // Command buffer to be sumitted to the queue
    m_submitInfo.commandBufferCount = 1;
    m_submitInfo.pCommandBuffers = &m_drawCmdBuffers[m_currentBuffer];

    // Submit to queue
    if (m_prepared) {
        VK_CHECK_RESULT(vkQueueSubmit(m_queue, 1, &m_submitInfo, VK_NULL_HANDLE));/////<-------crash
    }

    submitFrame();
    m_signalFrame = true;
}
