Open Source UML Tools

The embedded Finite State Machine (FSM) Facility that can be used to model and control a reactive or stateful system. The system can be represented by any number of states. State transitions are driven by a number of events. eFSM is written in C.

Our goal is to develop a full working solver for ATA (with 1 clock) in Python, with MTL to ATA support. The decidability for the emptiness problem was proposed by Lasota and Walukiewicz. The MTL to ATA was proposed by Ouaknine and Worrell.

That project aims at providing a clean API, and the corresponding C++ implementation, for the basis of Airline IT Business Object Model (BOM), ie, to be used by several other Open Source projects, such as RMOL, Air-Sched, Travel-CCM, OpenTREP, etc.

EasyCP is a modern, user-friendly C++ library that lets you use constraint programming in a very natural way, taking advantage of its expressive power. Just model and let the CSP (Constraint Satisfaction Problem) solver do the job !

Japrosim is a java library for both discrete event and continuous simulation. GUI for modeling and automatic code generation are offered. An explanation module is integrated. Models are described in XML and owl for interoperability.

JUMLStateMachine is a Java library implementing a state machine by the UML standard. The purpose for the library is to be easily usable for small state machines, yet extendable and scalable for larger and more complex ones.

Briefly said, PetriNetExec is an open-source Java library which allows you to embed Petri Nets into your Java application. Using PetriNetExec you can define places and transitions, connect them using arcs and inhibitors, define the initial marking and then fire events and see how tokens flow into the network. * PetriNetExec does not provide a GUI for editing the network nor will it provide in the near future. That is not really a feature :-) but to those of you able to cope with this news I suggest to read further; * Petri Nets are created with PetriNetExec by writing Java code and using the provided API; * PetriNetExec provides a simple yet powerful callback mechanism allowing you to actually do something when events are fired and the network status is changing. * PetriNetExec is embeddable into your Java application. This means that you can build your own application and add Petri Nets into it. * PetriNetExec is open-source.

This is an entity relationship diagram visualization widget programmed on QT4. With this tool you can draw objects (computers, people, whatever), and the relationship between them.

GLOB allows OpenGL programmers to create a variety of 3D meshes ranging from spheres, cubes and cyliders to NURBS and extrusions. GLOB compiles under Windows, Linux-based OSs and MAC. The library is compatible with OpenGL 4.0+ and doesn't use any deprecated features. 4 attrributes: 4D color, 3D normal, 3D position and 2D texture coordinate are stored per vertex in VAO (Vertex Array Objects). GLOB doesn't do any rendering to the screen and only builds the attributes for the mesh. Thus, the user must provide his own shader programs. However, if there is no current shader program registered, a default one is used which will depict the mesh under simple lighting and texture map. The GLOB API is very simple and intuitive to use, providing opportunities for customization, including that of normal and texture mapping.

instantFSM is a header-only C++ state machine library. Its goal is to make state machine declaration and use easy enough that it can be integrated into your projects painlessly. Have a look atp the wiki where you will find a tutorial, samples, and a cheatsheet to get accustomed with instantFSM. The only instantFSM header file is downloadable from the files section or you can check it out from the git repository.

Clothes - sewing CAD for creation of models of clothes. Based on the new concept of the automated designing of clothes with use of parametrical model. Creates a base design of model of clothes and allows to change it depending on necessity of updating.
