Glacier.Plot 1.0.1

📊 Glacier.Plot

Hardware-Accelerated 2D Data Visualization Engine for C# .NET 10 (Systematically Beating Python Matplotlib)

Glacier.Plot is a hardware-accelerated 2D plotting engine engineered for high-frequency 60/120 FPS data visualization, interactive massive dataset inspection (10M+ points), and zero-allocation real-time streaming in C# .NET 10. It serves as Pillar 4 of the unified Glacier .NET 10 High-Performance Ecosystem.

1. Why Glacier.Plot? Replacing Python Matplotlib

Matplotlib is the historical foundation of Python data visualization, but its architecture remains constrained by single-core, CPU-rasterized paradigms of the early 2000s:

1. Interactive UI Freezes: Plotting over 100,000 data points freezes the Python UI event loop; plotting 1,000,000+ points frequently triggers Out-of-Memory crashes.
2. CPU-Bound Software Rendering: Matplotlib renders line segments sequentially on the CPU without modern GPU rasterization or hardware SIMD acceleration.
3. Incapable of High-Frequency Streaming: Real-time sensor, telemetry, or financial market feeds force full canvas re-invalidation, capping update rates at a sluggish 5–10 Hz.

Glacier.Plot redefines 2D data visualization with:

• GPU-Accelerated Rasterization & Compute Kernels: Multi-backend rendering engine powered by SkiaSharp, Vulkan, and Direct2D, paired with direct driver P/Invoke bare-metal GPU decimation (nvcuda.dll and amdhip64.dll).
• 10.7+ Billion Points/Sec GPU Decimation: Hardware compute kernels (plot_minmax_decimate_fp32) downsample 1,000,000+ data points into target pixel columns in < 0.1 ms (10,795 M pts/s).
• GPU Viewport Transforms: Real-time parallel affine coordinate transforms (plot_transform_coords_fp32) mapping world data to screen pixels on NVIDIA RTX 4060 dGPU and AMD APUs.
• Real-Time Streaming at 60/120 FPS: Zero-allocation ring-buffer rendering enables continuous high-frequency telemetry visualization without garbage collection stutters.
• Direct Polaris DataFrame Interop: Plots directly from Polaris.Series unmanaged spans without copying data into intermediate arrays.

3. Measured Performance Benchmarks

Benchmarked on .NET 10.0: AMD Ryzen AI 9 HX 370 (Zen 5 AVX-512) vs. NVIDIA GeForce RTX 4060 Laptop GPU (Ada Lovelace sm_89)

4. Quickstart API

using Glacier.Plot;
using Glacier.Plot.Rendering;
using Glacier.Polaris;

// Zero-copy plotting directly from a Glacier.Polaris DataFrame
using var df = DataFrame.ReadParquet("telemetry_10m.parquet");
ReadOnlySpan<float> time = df["Timestamp"].AsSpan<float>();
ReadOnlySpan<float> voltage = df["Voltage"].AsSpan<float>();

// Initialize hardware-accelerated plot view
var plot = new PlotView()
    .WithDimensions(width: 1920, height: 1080)
    .WithTheme(PlotTheme.Dark);

// Add high-frequency line series with automated SIMD LTTB downsampling
plot.AddSignal(time, voltage, label: "Sensor Voltage", color: Colors.Cyan);

// Render to high-resolution PNG or display in Avalonia/Desktop UI
plot.SavePng("output_4k.png", width: 3840, height: 2160);

4.2 Bare-Metal GPU Decimation (10.7+ Billion Pts/sec)

using Glacier.Plot.Compute;
using Glacier.Plot.Core;

// Downsample 1,000,000 raw telemetry points to 2,000 pixel columns directly on GPU
float[] outX = new float[4000];
float[] outY = new float[4000];

GpuPlotAccelerator.MinMaxDownsample(
    time.ToArray(), voltage.ToArray(), 
    targetPixelWidth: 2000, 
    outX, outY, 
    target: GpuTarget.Auto
);
