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. \ No newline at end of file diff --git a/Virtual

10/16] refactor(structure): move CRT_shader.h to new include path and remove old shader directory Move CRT_shader.h to the shared include location to align with other shader headers. - Relocate CRT_shader.h to /Common/Include/Shaders/CRT_shader.h - Delete all contents of the old Virtual Display Driver (HDR)/Common/Shaders and remove the now-empty directories - Remove the obsolete Virtual Display Driver (HDR)/Common directory - Update internal build references to use the new header path BREAKING CHANGE: Removed the old include path under /Virtual Display Driver (HDR)/Common and its Shaders directory; update includes to /Common/Include/Shaders/CRT_shader.h where appropriate. --- .../Include}/Shaders/CRT_shader.h | 968 +++++++++--------- .../Common/Shaders/README.md | 115 ---

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;

Shader bytecode can be loaded at runtime via a controller pipe and toggled on/off via pipe commands. Routing of shader execution is controlled by igpu-shader XML setting, allowing iGPU to render on the shared texture when enabled. ### Summary Introduce DXGI shared texture resources and mutex-based synchronization to perform GPU shader rendering on a shared target without RAM copies. Shader bytecode can be uploaded through a pipe channel and executed in a GPU-resident path. ### Details - Add shared texture, keyed mutex, SRV/RTV and shader state to Direct3DDevice - Implement pipe commands: loadshader, shader_enable, shader_disable; store shader bytecode in driver memory - Read igpu-shader from vdd_settings.xml and route shader path to iGPU or dGPU - Integrate shader execution into SwapChainProcessor using keyed mutex coordination - Ensure textures are created with D3D11_RESOURCE_MISC_SHARED | D3D11_RESOURCE_MISC_SHARED_KEYEDMUTEX - No host RAM copies; all shader operations stay on GPU; minimal impact on existing DXGI flow --- .../MttVDD/Driver.cpp | 245 +++++++++++++++++- Virtual Display Driver (HDR)/MttVDD/Driver.h | 41 +++ Virtual Display Driver (HDR)/vdd_settings.xml | 1 + 3 files changed, 286 insertions(+), 1 deletion(-) diff --git a/Virtual Display Driver (HDR)/MttVDD/Driver.cpp b/Virtual Display Driver (HDR)/MttVDD/Driver.cpp index 467e105..b47a489 100644 --- a/Virtual Display Driver (HDR)/MttVDD/Driver.cpp +++ b/Virtual Display Driver (HDR)/MttVDD/Driver.cpp @@ -48,6 +48,7 @@ Copyright (c) Microsoft Corporation #pragma comment(lib, "xmllite.lib") #pragma comment(lib, "shlwapi.lib") +// #--- #pragma comment(lib, "d3dcompiler.lib") HANDLE hPipeThread = NULL;
