Protracer is a simple raytracer originally written in 1999 as a university course project. Please be aware that, despite the name, there is nothing especially professional about Protracer. The name is meant to be a pun on the Protracker music tracker application. It currently supports a very limited subset of the POV-Ray file format.
The qpfcalc application is a Qt frontend for pfcalc, a CLI pipe friction calculator. It is similar to gpfcalc, the GTK+ frontend for pfcalc. There are two versions of qpfcalc, one for Windows and one for Linux. The Linux version should be easy to compile and run on any Unix-like operating system with few minor modifications. For the application to function properly the pfcalc backend must be installed. For the Windows version, this is not needed as qpfcalc is distributed along with all the files needed to run, including pfcalc and Qt libraries.
GêBR is a simple graphical interface that facilitates geophysical data processing. While it is not a package for processing, it is designed to integrate a large variety of free processing packages. It can handle Projects and Lines, assemble and run processing sequences, and act as an interface to many freely-available seismic-processing packages (such as Seismic Unix, Madagascar, etc.)
