The World's Fastest .NET WPF, WinForms, and MFC C++ Charting Components. GPU compute shader accelerated. AI-assisted development. Intelligent rendering. Mission-critical quality since 1993.

Founded in 1993, Gigasoft has concentrated exclusively on charting for over 30 years — scientific, engineering, and financial data visualization at a mission-critical level. Prioritizing stability, speed, and rendering intelligence. Fast expert support. No hassle evaluation download.

ProEssentials is architecturally different from every competitor — a native Win32 DLL charting engine with two complete API layers: a hierarchical .NET property interface for WPF and WinForms, and a standard C/C++ DLL API for MFC, Delphi, ActiveX, and any language with DLL FFI capability. Both APIs access the same rendering engine, the same GPU compute shaders, and the same 1,200+ chart properties.

ProEssentials v10 includes a purpose-built AI Code Assistant that transforms how you implement charts. The pe_query.py tool gives AI assistants on-demand access to the complete ProEssentials API — 1,200+ properties, 167 enumerations, and 116 working code examples — with a built-in validation layer that cross-checks every property path against DLL ground truth, eliminating the hallucinated code that plagues generic AI coding.

Works with Claude, ChatGPT, Gemini, GitHub Copilot, and Cursor. Included free with every ProEssentials v10 license.

GPU-accelerated 3D surface, height-map, point cloud, and Delaunay triangulation charts for scientific, engineering, and terrain visualization in WPF and WinForms.

Preview	Demo
	3D Surface Height Map (flagship 3D/2D demo) WPF Likely the most impressive functioning, performing, efficient 3D/2D combo example you will find on GitHub. A .NET 8 demonstration of GPU compute shader 3D surface rendering — real material surface and terrain height-map data visualized across three synchronized charts.
	3D LiDAR Point Cloud — 2.5M Returns WPF · WinForms .NET 8 demonstration of the v10.0.0.24 ComputeShader path for PolyMode = Scatter — rendering 2.5M Mt. Tamalpais LiDAR returns as a 3D scatter cloud with every point individually colored by elevation.
	3D Delaunay Triangulation Surface WPF · WinForms .NET 8 — a Pe3do Delaunay-triangulated 3D surface with contour coloring, built from 70 scattered XYZ sound-meter readings. Direct3D.
	Delaunay Triangulation 2D Contour WPF · WinForms .NET 8 — a Pesgo continuous Delaunay contour fill (SGraphPlottingMethod.ContourDelaunay) from 70 scattered XYZ sound-meter readings, with a custom tooltip and a title-bar interpolated-Z readout. Direct3D composite.

Well log, cement bond log (VDL), ultrasonic borehole imaging, wellbore trajectory, and NEXRAD radar charts for oil & gas, geophysical, and GIS software.

Preview	Demo
	3D Wellbore Flythrough (Oil & Gas GIS) WPF · WinForms .NET 8 — a complete 3D subsurface visualization with an animated roller-coaster style camera flythrough down multiple wellbore trajectories, using a single Pe3do Direct3D chart object.
	VDL Wireline Acoustic — Cement Bond Log WPF · WinForms .NET 8 — a wireline Variable Density Log (VDL) acoustic visualization for cement bond evaluation. Time on X (~200–1200 µs), depth on Y (feet), color = waveform amplitude, rendered with a contour-with-injection technique that keeps cells crisp at scale. Direct3D + GPU compute shader, custom 8-stop blue ramp.
	Ultrasonic Borehole Image — Dual Contour WPF · WinForms .NET 8 — dual-channel ultrasonic borehole image (AWCN amplitude + TTCN transit time) rendered as a single concatenated contour chart sharing one colormap, one zoom, one rendering pass. A top-right overlay button toggles null rendering (Black / Gaps). Direct3D + GPU compute shader.
