Open Source Objective C Scientific/Engineering Software

Skim is a PDF reader and note-taker for OS X. It is designed to help you read and annotate scientific papers in PDF, but is also great for viewing any PDF file. Skim requires OS X 10.10 or higher.

Video Projector/Monitor Calibration Software orginally developed as ColorHCFR. This code base is based off version 2.1 and will aim for a more open development process. The opensource version integrates an ArgyllCMS interface for continued meter support and development. If you feel the program has been of value to you since I started working on it about 3 years ago please consider a contribution via the link below. Thanks! -zoyd https://www.paypal.me/zoyd

Lynkeos is a Cocoa® application dedicated to the processing of astronomical digital images taken through a telescope. It is optimized for SSE vectorized instructions sets, multi-processor and multi-core machines.

A multiplatform C++ library for dynamic generation of Excel .xls files containing multiple worksheets. Unlike .csv files, these can be directly opened by Excel and thus provide an excellent way to output large data sets that require further analysis. To see the latest changes, select "Files" and view the README text displayed at the bottom of that pane. IMPORTANT: Major changes are contained in the current SVN source. If you have time please try to use it or the xlslib-package-2.4.0b1.zip archive, and enter bug reports on any problems! Changes: - library specific strings now in their own namespace - iOS Objective-C library - most project files updated (MSVS etc) - C bridge now supports formulas Note: there is a related SF project, libxls, to read Excel files.

Darling is a free and open source runtime compatibility layer—akin to Wine—for Linux that allows native macOS (Darwin) applications to run directly without hardware emulation. It implements macOS libraries and frameworks, enabling macOS binaries to execute on Linux. Darling has support for DPREFIXes, which are very similar to WINEPREFIXes. They are virtual “chroot” environments with an macOS-like filesystem structure, where you can install software safely. The default DPREFIX location is ~/.darling, but this can be changed by exporting an identically named environment variable. A prefix is automatically created and initialized on first use. Please note that we use overlayfs for creating prefixes, and so we cannot support putting prefix on a filesystem like NFS or eCryptfs. In particular, the default prefix location won't work if you have an encrypted home directory.

DarwiinRemote is a tiny program & library which reads data from and sends data to Nintendo Wii Remote (Wiimote), nunchuk, & classic controller.

FastEasyMapping is a lightweight and high-performance framework designed for mapping JSON or other data formats into native Objective-C objects on iOS. It simplifies the process of converting raw data into models and is built with a focus on speed and efficiency, making it suitable for apps dealing with large datasets or frequent network responses.

A native Macintosh front-end and distribution for the GAP computer algebra system. It provides a Mac-like command editing environment and save/load, while making available graphical libraries compatible with xgap.

N.B. SuperCollider is now hosted at GitHub, and the most recent versions can be downloaded from there. http://supercollider.github.io A real time audio synthesis engine, and an object-oriented programming language specialised for music. SuperCollider was created in 1996 by James McCartney, now (since version 3) released as free software.

RSM (Radiation Spectrum Method) is a 2D rigorous tool to solve the Maxwell equations for the propagation of light in integrated optics or photonics devices. It makes use of an EigenMode Expansion method (EME) to solve the electromagnetic problem. This software running on Windows and MacOS comes with a GUI that permits to define with the aid of files or scripts the arbitrary and complex geometry of the waveguide. Of that way any waveguide geometry can be handled. Several plots are available : refractive index plot, field propagation plot and modes spectrum plot. This permits, with the interpretation of the guided and radiation modes spectrum, a physical understanding of the propagation mechanisms in the integrated optical device under evaluation. The complex geometry of the component is discretized in a stack of multilayer dielectric waveguides. For Windows, download "RSM_visit_update2.zip" , this file needs the last version of the software be first installed : "RSM VisitSetup2.ex

ArchiScale is an easy-to-use Mac OS X software that converts distances using a user-defined scale. It is also able to determine which scale is the best to draw something on a given paper format. This software is useful for students in first years of architecture schools, when you work without CAD-softwares, and for people using non-numerised documents with uncommon scales.
