Algodoo

Algodoo ( ) is a physics-based 2D freeware sandbox from Algoryx Simulation AB (known simply as Algoryx) as the successor to the popular physics application Phun. It was released on 31 August 2009 and is presented as a learning tool, an open-ended computer game, an animation tool, and an engineering tool. The software is functional with desktop and laptop computers, touch screen tablets, and interactive white board systems such as SMART Boards. The physics engine in Algodoo utilizes the SPOOK linear constraint solver by Claude Lacoursière and a modified version of the Smoothed-Particle Hydrodynamics (SPH) computational method. On the App Store, it costs US$7.99 and is only available for iPadOS. This program has been used by many people including educators, students, and children. Algodoo has remained as a popular choice from websites like List Of Freeware and Download Cloud for a physics sandbox program due to its complexity, simple GUI and free price.

Two notable changes include a new optics modeling engine and a snap-to-grid feature allowing for higher precision scene creation. The inclusion of the optics modeling engine granted much more freedom in terms of using Algodoo's scripting language, Thyme, as users were thereafter able to initiate events by hitting an object with a stream of laser light. Other notable changes include the addition of a velocity menu, which allows users to set a geometry's velocity to a set value; incompressible water, which allows for much more realistic fluid simulation; the plotting menu; vector visualization; and many other new features, bug fixes, and improvements. ==File sharing== Originally, the upload system for Phun was hosted by a small website at the Academic Computer Club from Umeå University. The upload system was later moved to a Phunland site in an upload subdirectory and then moved again to the Phunbox file sharing directory created by Zuriki and Lukas Wolf (which contained 16,874 user uploads ). After several more changes to the upload system, the directory was finally moved to the Algodoo website under the name Doobox. After a user suggested that Doobox might not be a good name for the file sharing system (it was also the name of a software company ), the name was then changed to Algobox, which was suggested by Chronos. Users of Algodoo can share the scenes they create via Algobox; the platform currently houses over 200,000 user-created scenes and is continuing to rise. Due to the decrease in the number of recent updates and Algodoo becoming free in 2013, many users have assumed that Algodoo is discontinued. After this, many long-time users abandoned the program, causing a sharp decline in scene submissions. However, in April 2024, Algoryx announced the beta for version 2.2.0. Afterwards, 2.2.1, 2.2.2, 2.2.3 released publicly, with Algodoo 2.2.4 being the latest version as of August 2026¹. ==References== ==External links== Algodoo website Algoryx website
