RenderGraph is the core rendering system of the engine, providing:

• Automatic dependency management and topological sorting
• Flexible Pass system (ClearPass, OpaquePass, OITPass, CompositePass, PresentPass)
• Automatic resource management (RenderTarget, DepthStencil, ShaderResource)

For detailed usage guide, please refer to RenderGraph Guide

The engine supports the following component types:

• MeshComponent: Mesh rendering
• MaterialComponent: Material properties
• SkeletonComponent: Skeletal animation
• NvFlexComponent: Flex physics simulation
• CameraComponent: Camera
• TransformComponent: Transform matrix
• NameComponent: Entity naming

• Windows 10/11
• Visual Studio 2019 or higher
• DirectX 11 compatible graphics card
• Qt 6.x SDK (for editor)
• CMake 3.15+ (optional)

1. Clone the repository

git clone https://github.com/leafvmaple/Zongine.git
cd Zongine

2. Initialize submodules (if any)

git submodule update --init --recursive

3. Open the solution

# Open with Visual Studio
start Zongine.sln

4. Configure Qt environment

   • Ensure Qt Visual Studio Tools extension is installed
   • Configure Qt 6 path

5. Build the project

   • Select Debug or Release configuration
   • Build the Editor project or Simple example project

After building, run Editor.exe:

.\x64\Debug\Editor.exe
