This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
Ray tracing is a technique that can generate near photo-realistic computer images. A wide range of free software and commercial software is available for producing these images. This article lists notable ray-tracing software.
Ray tracing of a beam of light passing through a medium with changing refractive index.The ray is advanced by a small amount, and then the direction is re-calculated. Ray tracing works by assuming that the particle or wave can be modeled as a large number of very narrow beams (), and that there exists some distance, possibly very small, over which such a ray is locally straight.
RadExPro is a Windows-based seismic processing software system produced by RadExPro Seismic Software LLC based in Georgia. It is suitable for in-field QC (both online and offline) and processing of 3D and 2D marine and on-land seismic data, advanced processing of HR/UHR offshore seismic, [1] as well as for the onshore near-surface seismic reflection, refraction, MASW, and VSP processing.

Seismic tomography or seismotomography is a technique for imaging the subsurface of the Earth with seismic waves produced by earthquakes or explosions. P- , S- , and surface waves can be used for tomographic models of different resolutions based on seismic wavelength, wave source distance, and the seismograph array coverage. [ 1 ]
Tachyon is a parallel/multiprocessor ray tracing software. It is a parallel ray tracing library for use on distributed memory parallel computers, shared memory computers, and clusters of workstations. Tachyon implements rendering features such as ambient occlusion lighting, depth-of-field focal blur, shadows, reflections, and others.
The seismic survey design software can be used to design seismic survey in offshore, onshore, subsurface coverage analysis for 3D/3C and Vertical seismic profile surveys. Also survey cost analysis, project tracking, crew production statistics can be managed. Other modelling studies such as ray tracing and illumination analysis can also be done.
