Gnuplot is a portable multi-platform command-line driven graphing utility. It was originally created to allow scientists and students to visualize mathematical functions and data interactively, but has grown to support many non-interactive uses such as web scripting. It is also used as a plotting engine by third-party applications like Octave. Gnuplot has been supported and under active development since 1986. This port installs extra files for TeX terminals (latex, epslatex, Tikz, etc).

FaCiLe is a constraint programming library on integer and integer set finite domains written in OCaml. It offers all usual facilities to create and manipulate finite domain variables, arithmetic expressions and constraints, built-in global constraints and search and optimization goals. FaCiLe allows as well to build easily user-defined constraints and goals, making pervasive use of OCaml higher-order functionals to provide a simple and flexible interface for the user.

PDAL is a BSD licensed library for translating and manipulating point cloud data of various formats. It is a library that is analogous to the GDAL raster library. PDAL is focussed on reading, writing, and translating point cloud data from the ever-growing constellation of data formats that are being developed for working with multi-dimensional emitted-pulse scanning systems. While PDAL is not explicitly limited to working with LiDAR data formats, its initial rollout is focused in that area.

A class of units of physical quantities for Ruby. This class covers most functionality of UNIDATA's UDUNITS Library, however, with a more sophisticated handling of string expressions. UDUNITS always decomposes units into the four base units and discards the original string expressions. Therefore, 'hPa' always becomes '100 kg.m-1.sec-1', and 'day' always becomes '86400 sec'. On the other hand, this library tries to keep the original expressions as much as possible by default, while allowing partial to complete decompositions if needed.

sfft is a library to compute discrete Fourier transforms of signals with a sparse frequency domain, using an algorithm that is more efficient than other known FFT algorithms. It was developed by Haitham Hassanieh, Piotr Indyk, Dina Katabi, and Eric Price at the Computer Science and Artifical Intelligence Lab at MIT. Performance optimizations were developed by J. Schumacher at the Computer Science Department of ETH Zurich in 2013.

The utility allows you to download firmware into and upload firmware from the memory of a Cypress EZ-USB/FX2/FX3 chips. It is a de facto standard for programming this family of devices. This port is based on original fxload(8) program available from Linux Hotplug Project. Libusb support has been provided to correctly work on FreeBSD and patches for the FX3 have been merged in.

gtkfind is the program to use when you don't want to have to remember all the options to find(1). It is a graphical program that allows you to search for files and (optionally) perform operations on them. You can search for files by using wildcards, by matching file types and/or permissions, etc. gtkfind requires X and the GTK+ toolkit. It is still under development, but has reached a stage where it is actually useful.

Fxtv is an X11-based FreeBSD app that provides TV-in-a-window and image/audio/video capture capabilities for Brooktree Bt848/849/878/879 and Pinnacle PCTV tuner/capture cards. To use this app, you need a capture card supported by the bktr(4) driver. Examples include the Hauppauge Wincast/TV, the STB TV PCI, and the Intel Smart Video Recorder III. See the 'bktr' man page for more information.

libfame is a video encoding library. It can currently encode MPEG-1 and MPEG-4 rectangular video, as well as MPEG-4 video with arbitrary shape. Objectives - Compliance : Provide bitstreams compliant to the MPEG-1, MPEG-2 and MPEG-4 video standards. - Speed : Provide a fast implementation of the techniques used in MPEG standards. - Flexibility : Allow the user to choose between different options for speed, compression ratio and quality. - Portability : Support many different platforms and architectures.

From the README: MPEG Video Software Statistics Gatherer (Version 2.2; Feb 1, 1995) Lawrence A. Rowe, Steve Smoot, Ketan Patel, and Brian Smith Computer Science Division-EECS, Univ. of Calif. at Berkeley This directory contains a public domain MPEG video statistics gatherer. The decoder implements the standard described in the Committee Draft ISO/IEC CD 11172 dated December 6, 1991 which is sometimes referred to as "Paris Format." eric. erich@FreeBSD.org
