# D3D12 Integration Tests

## minimal
**后端**: D3D12Device, DXGIFactory, CommandQueue, CommandList, SwapChain
**内容**: 最小 D3D12 初始化流程，创建窗口和交换链，无渲染输出

## triangle
**后端**: D3D12Device, DXGIFactory, CommandQueue, CommandList, SwapChain, Buffer, Shader, RootSignature, PipelineState, RenderTargetView, DepthStencilView, Screenshot
**内容**: 
- 基础三角形渲染
- 顶点 buffer 上传
- HLSL shader 编译 (vs_5_1, ps_5_1)
- Root signature + PSO 创建
- RenderTarget 切换 (Present ↔ RenderTarget)
- 截图功能验证

## quad
**后端**: triangle 的全部 + Texture, DescriptorHeap, ShaderResourceView
**内容**:
- 四边形纹理采样渲染
- Texture 加载与初始化 (stb_image)
- DescriptorHeap (CBV_SRV_UAV) + SRV 创建
- 静态采样器配置
- Root signature descriptor table
- SetDescriptorHeaps + SetGraphicsRootDescriptorTable
- 截图功能验证

## render_model
**后端**: (TODO)
**内容**: 模型渲染 (待实现)
