llgi's Introduction

LLGI

How to build

Windows

$ git clone https://github.com/altseed/LLGI.git
$ cd LLGI
$ git submodule update --init
$ cmake -S . -B build -DBUILD_TEST=ON
$ cmake --build build

macOS

$ git clone https://github.com/altseed/LLGI.git
$ cd LLGI
$ git submodule update --init
$ cmake -S . -B build -G "Xcode" -DBUILD_TEST=ON
$ cmake --build build

Vulkan(Window, Linux)

$ git clone https://github.com/altseed/LLGI.git
$ cd LLGI
$ git submodule update --init
$ cmake -S . -B build -DBUILD_VULKAN=ON -DBUILD_TEST=ON
$ cmake --build build

Test

Run with Vulkan

./LLGI_Test --vulkan

Run with single test

./LLGI_Test --filter=<TestName*>

llgi's Issues

Implement MRT

Add a test where Depth is used as a texture

Implement async ComputeShader

Enable Texture in compute shader

To use VectorField for 3D textures in GpuParticles

Implement Instancing

Support MSAA

Implement stencil detail flags

Support Stencil buffer

Generate shaders with SPIR-V

Swapchain の backbuffer を LLGI.Texture でラップして公開する

キャプチャの API で任意のバッファから読み取れるようにするため、Swapchain の backbuffer を、LLGI.Texture でラップして公開するような API を実装する。

次のように使えるようにしたい。

auto renderPass = graphics->GetCurrentScreen(color, true);
auto texture = renderPass->GetColorBuffer(0);
auto data = graphics->CaptureRenderTarget(texture);

Implement a cube texture

how to build tools (ShaderTranspiler, glslangValidator)

Build ShaderTranspiler on Windows

cmake -S . -B build -DBUILD_TEST=ON -DBUILD_TOOLS=ON
cmake --build build

Build glslangValidator on Windows

cd thirdparty/glslang
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX="$(pwd)/install"
cmake --build . --config Release --target install
cp StandAlone/Release/glslangValidator.exe ../../../scripts/.

Implement mipmap in a texture

Implement divisor

Implement CreateTexture with new args

implement these functions

Texture* Graphics::CreateTexture(const TextureInitializationParameter& parameter);

Texture* Graphics::CreateRenderTexture(const RenderTextureInitializationParameter& parameter) ;

Texture* Graphics::CreateDepthTexture(const DepthTextureInitializationParameter& parameter);

Implement CreateCommandList with args

Implement

CommandList* Graphics::CreateCommandList(SingleFrameMemoryPool* memoryPool);

Graphics からSwapchain 関係の処理とデータを分離する

Unity 組み込みなどを見据えて、Swapchain 関係を Graphics から分離する。
GetCurrentBuffer は Platform に持たせる。

現状：

auto renderPass = graphics->GetCurrentScreen(color, true);
...
platform->Present();

変更後：

auto renderPass = platform->GetCurrentScreen(color, true);
...
platform->Present();

fix typo from "Barrior" to "Barrier"

support new specifications

Screenshot

It is not implemented on all backends.

CreateCommandList with args

except Metal

Support SendTextureFromCPUToGPU

Implement a command to transfer a data and remove Lock,Unlock

Current version

auto b = buffer->Lock();
memset(b, ...);
buffer->Unlock();

Ideal version

commandBuffer->SetData(buffer, srcData, size);

Note

I seem that it may should support a function to assign a initial data when creating

CommandListのDispatchを同期実行できるようにする。

DX12 と Vulkan では、CommandList の Dispatchが同期実行されない。そのため、一度に複数のDispatchを行うと、複数のComputeShaderが並列に実行されてしまって意図しない出力になる可能性がある。そのため、Dispatch する際に各 ComputeBuffer に対してResource Barrier を行い、同期的に実行されるようにする。

Implement custom memory allocators

separate Swapchain functions and data from CommandList

I want to remove data of multiple swapbuffer from LLGI.CommandList.
CommandList should be created by a swapbuffer

Current version

auto platform = LLGI::CreatePlatform(LLGI::DeviceType::Default);
auto graphics = platform->CreateGraphics();
auto sfMemoryPool = graphics->CreateSingleFrameMemoryPool(1024 * 1024, 128);
auto commandList = graphics->CreateCommandList(sfMemoryPool);

while ()
{
    platform->NewFrame();
    sfMemoryPool->NewFrame();
    
    commandList->Begin();
    ・・・
    commandList->End();

    graphics->Execute(commandList);

    platform->Present();
}

Ideal vesion

auto platform = LLGI::CreatePlatform(LLGI::DeviceType::Default);
auto graphics = platform->CreateGraphics();
auto commandListPool = graphics->CreateCommandListPool(1024 * 1024, 128, the number of swap chain);    // including MemoryPool

while ()
{
    platform->NewFrame();
    
    auto commandList = commandListPool->get();    // Wait to finish execution of command list 
    
    commandList->Begin();
    ・・・
    commandList->End();

    graphics->Execute(commandList);

    platform->Present();
}
