Vic-3D 9.4.22 is a specific build within version 9 of the Vic-3D digital image correlation (DIC) software suite by Correlated Solutions, Inc. Released as part of the version 9 series in late 2021, this build refines the core DIC engine, enhances visualization, and improves workflow stability. Vic-3D is a non-contact, full-field measurement system for three-dimensional shape, displacement (U, V, W), and strain analysis on non-planar surfaces using stereo-camera setups. It delivers sub-pixel displacement accuracy (down to 0.01 pixel) and strain resolution as low as 10 microstrain, making it a go-to solution for mechanical testing, fracture mechanics, vibration analysis, and biomaterial studies. As of October 2025, version 10 is the latest, but 9.4.22 remains widely used for its robust performance in quasi-static and high-speed applications.
Key Features in Vic-3D 9.4.22
The stereo DIC correlation engine in Vic-3D 9.4.22 uses advanced subset-based algorithms to compute full-field 3D displacements and strains (ε_xx, ε_yy, ε_zz, ε_xy, etc.) at every pixel, supporting strains up to 2000% and high-speed events up to 1 MHz. It processes data efficiently on quad-core CPUs, enabling real-time analysis for dynamic testing. The integrated iris graphics engine produces high-resolution, publication-ready outputs, including PDFs, multi-page plots, and 4K MP4 videos, with multi-threaded rendering, scalable fonts, isoline contours, and overlays for finite element analysis (FEA) validation.
For FEA integration, Vic-3D allows direct import of results from tools like Abaqus or ANSYS, enabling stress-strain correlation with error metrics and automated hot-spot detection for design validation. The virtual extensometer/gauge tool extracts real-time displacements and strains at user-defined regions of interest, customizable for multi-axial measurements during live testing or post-processing.
Advanced filtering options include user-defined strain filters (localized or averaged) and temporal noise reduction for time-series data, with Python scripting support via the VICPy library for batch automation and custom calculations, such as principal strains. The software also features distortion correction for stereo microscopes and scanning electron microscopes (SEM), drift compensation for high-speed cameras, and compatibility with IR/thermal data fusion in later builds.
Post-processing is streamlined with batch processing for multi-image sets, automated hot-spot detection for strain concentrations, and flexible exports to CSV, Excel, or MATLAB. Build 9.4.22 specifically improves multi-monitor UI responsiveness and accelerates region-of-interest alignment, addressing minor bugs reported in earlier builds.
