+# Virtual Display Driver Shader Examples
+
+This directory contains example HLSL shaders for the Virtual Display Driver (HDR), demonstrating different visual effects that can be applied to virtual displays.
+
+## Shaders Included
+
+### 1. Vortex Shader (`vortex_shader.h`)
+- **Effect**: Split-screen effect with blue and red colored halves
+- **Features**:
+  - Left half: Blue with 40% opacity
+  - Right half: Red with 40% opacity
+  - Simple vertex/pixel shader pair for basic rendering
+- **Usage**: Good for testing basic shader functionality and color blending
+
+### 2. Wave Shader (`wave_shader.h`)
+- **Effect**: Animated wave with horizontal bottom bar
+- **Features**:
+  - White horizontal bar at the bottom (3 pixels tall)
+  - Animated sine wave that travels side-to-side
+  - Wave amplitude controllable via PerFrameBuffer
+  - Time-based animation
+- **Usage**: Demonstrates animated effects and real-time parameter control
+
+## File Structure
+
+Each shader consists of two files:
+- `.hlsl` - Source code (human-readable HLSL)
+- `.h` - Compiled header (ready for Direct3D integration)
+
+## Compilation Instructions
+
+### HLSL Source Files
+The `.hlsl` files can be compiled using the DirectX FX Compiler (fxc.exe):
+
+```cmd
+:: Compile vertex shader
+fxc.exe /T vs_5_0 /E VSMain /Fo vortex_vs.cso vortex_shader.hlsl
+fxc.exe /T vs_5_0 /E VSMain /Fo wave_vs.cso wave_shader.hlsl
+
+:: Compile pixel shader
+fxc.exe /T ps_5_0 /E PSMain /Fo vortex_ps.cso vortex_shader.hlsl
+fxc.exe /T ps_5_0 /E PSMain /Fo wave_ps.cso wave_shader.hlsl
+```
+
+### Integration with Direct3D 11
+The `.h` header files contain:
+- Pre-compiled shader bytecode as byte arrays
+- PerFrameBuffer structure definitions
+- Proper DirectX::XMFLOAT4 alignment for constant buffers
+
+### Usage Example
+```cpp
+#include "vortex_shader.h"
+
+// Create vertex shader
+ID3D11VertexShader* pVertexShader;
+pDevice->CreateVertexShader(VortexVSBytecode, VortexVSBytecodeSize, nullptr, &pVertexShader);
+
+// Create pixel shader
+ID3D11PixelShader* pPixelShader;
+pDevice->CreatePixelShader(VortexPSBytecode, VortexPSBytecodeSize, nullptr, &pPixelShader);
+
+// Create constant buffer
+D3D11_BUFFER_DESC cbDesc;
+cbDesc.ByteWidth = sizeof(PerFrameBuffer);
+cbDesc.Usage = D3D11_USAGE_DYNAMIC;
+cbDesc.BindFlags = D3D11_BIND_CONSTANT_BUFFER;
+// ... setup other desc fields
+
+ID3D11Buffer* pConstantBuffer;
+pDevice->CreateBuffer(&cbDesc, nullptr, &pConstantBuffer);
+
+// Update constant buffer data
+PerFrameBuffer frameData;
+frameData.resolution = DirectX::XMFLOAT4(1920, 1080, 0, 0);
+frameData.time = currentTime;
+frameData.padding = 0.0f;
+```
+
+## PerFrameBuffer Structure
+
+Both shaders use the same constant buffer structure:
+
+```cpp
+__declspec(align(16)) struct PerFrameBuffer
+{
+    DirectX::XMFLOAT4 resolution;  // Screen resolution (width, height, 0, 0)
+    float time;                     // Time elapsed in seconds
+    float amplitude;                // Wave amplitude (wave shader only)
+    float padding;                  // Padding for 16-byte alignment
+};
+```
+
+## Shader Profiles
+
+- **Vertex Shaders**: vs_5_0 (DirectX 11 feature level)
+- **Pixel Shaders**: ps_5_0 (DirectX 11 feature level)
+- **Constant Buffers**: register(b0) binding
+
+## Notes
+
+- All shaders use fullscreen quad geometry (typically created from screen-sized triangle strip)
+- Shader bytecode in headers is placeholder data - replace with actual compiled bytecode for production
+- The PerFrameBuffer is aligned to 16 bytes for DirectX constant buffer requirements
+- Both shaders are compatible with Direct3D 11 and later versions
+
+## Integration Points
+
+These shaders can be integrated into:
+- SwapChainProcessor for real-time display effects
+- Custom rendering pipelines
+- Debug/visualization modes
+- Performance testing scenarios
+
+Each shader demonstrates different HLSL techniques and can serve as a foundation for more complex visual effects.
