Real-Time Circular Buffer — 4 x 2M Points — WinForms

ProEssentials v10 WinForms .NET 8 — 4 subsets × 2,000,000 points streamed in real time via zero-copy UseDataAtLocation + CircularBuffers + Direct3D ComputeShader. A timer appends 150 samples/subset every 15ms; a right-click submenu toggles Stationary vs Scrolling zoom.

What This Demonstrates

• Zero-copy streaming — UseDataAtLocation points the GPU staging buffers directly at app-owned arrays; AppendData wraps in the ring with no realloc.
• 8M points (4 × 2M) with Filter2D3D lossless pixel-level reduction.
• Custom right-click submenu (PeCustomMenu) toggling zoom-follow behavior.
• Code-built UI — chart + timer + menu handler in MainForm.cs; no .Designer.cs / .resx.

WinForms vs WPF

All chart configuration, the data generation, the AppendData logic, and the PeCustomMenu handler are identical to the WPF version. Host changes: DispatcherTimer → System.Windows.Forms.Timer (Interval = 15), System.Drawing.Color, and the timer is stopped in Form.FormClosing.
