3D Delaunay Triangulation Surface Heightmap — WinForms

ProEssentials v10 WinForms .NET 8 — a Pe3do Delaunay-triangulated 3D surface with contour coloring, built from 70 scattered XYZ sound-meter readings. Direct3D.

• Delaunay3D surface (PePlot.Option.Delaunay3D = true, Surface-with-Contour method) from an unstructured point cloud — no regular grid required.
• Per-point 3D annotations (dot + dBA label) and a bottom contour projection.
• Custom 6-stop contour color ramp, manual contour range, hero camera.
• Code-built UI — single chart in MainForm.cs; no .Designer.cs / .resx.

The data loader and the entire Pe3do configuration are identical to the WPF version. Host changes: WinForms MessageBox, Application.Exit(), System.Drawing.Color, and Pe3doWpf → Pe3do.
