ZeroGraphics.Core 1.0.0

ZeroGraphics

High-performance, hardware-accelerated desktop graphics ecosystem for .NET (WinForms / WPF / Headless). Built with direct COM VTable P/Invoke — zero external dependencies (no SharpDX, no Vortice.Windows, no runtime D3DCompiler required).

Dual-targeted for legacy .NET Framework 4.6.2 enterprise apps (e.g., Industrial ERP, MES, SCADA) and modern .NET 8.0 / 9.0+ Windows.

🚀 Key Advantages

1. Zero External Dependencies:

   • Uses zero third-party NuGet packages for graphics.
   • All COM interfaces (ID3D11Device, IDXGISwapChain, ID2D1Factory, IDWriteFactory) communicate directly via pure C# [UnmanagedFunctionPointer] VTable delegates.
   • Shaders are precompiled via fxc.exe (Shader Model 4.0) and embedded directly as byte arrays — eliminating the need for d3dcompiler_47.dll at runtime.

2. Enterprise WinForms Integration (Single HWND):

   • Renders directly into standard WinForms Control.Handle via Direct3D 11 swap chains or Direct2D HwndRenderTarget.
   • On-demand rendering: redraws only when properties change or upon OS invalidation events (0.0% CPU and 0.0% GPU when idle).

3. Multi-Target Universal Compatibility:

   • ZeroGraphics.Core targets .NET Standard 2.0, .NET Framework 4.6.2, and .NET 8.0.
   • UI canvas libraries support .NET Framework 4.6.2 and .NET 8.0-windows.

📦 Package Matrix

⚡ Quick Start

1. Direct3D 11 Analytical SDF Card (WinForms)

using ZeroGraphics.DirectX.Controls;

var card = new ZeroDirectXCanvas
{
    Dock = DockStyle.Fill,
    Elevation = 12f,
    BlurRadius = 24f,
    CornerRadius = 16f,
    BorderWidth = 1.5f,
    GlowIntensity = 0.6f,
    CardColor = Color.FromArgb(24, 28, 38)
};
this.Controls.Add(card);

2. Direct2D DirectWrite Typography

using ZeroGraphics.Direct2D.Controls;

var textCanvas = new ZeroDirect2DCanvas
{
    Dock = DockStyle.Fill,
    TextFontFamily = "Segoe UI",
    TextSize = 16f,
    SampleText = "Subpixel ClearType with Per-Monitor V2 High-DPI Crispness"
};
this.Controls.Add(textCanvas);

3. Waveform High-Speed Oscilloscope (100k points)

using ZeroGraphics.Waveform.Controls;

var scope = new ZeroWaveformCanvas
{
    Dock = DockStyle.Fill,
    AutoScale = true,
    TraceColor = Color.FromArgb(0, 255, 136)
};
this.Controls.Add(scope);

// Stream live telemetry points
float[] points = GetTelemetryBuffer(); // 100,000 points
scope.SetData(points);

🧪 Verification & Tests

To execute the automated test suite:

dotnet test tests/ZeroGraphics.Tests/ZeroGraphics.Tests.csproj

To run the interactive demonstration application:
