LEDAS launches Academic licensing program for its variational geometric solvers LGS 2D/3D
LEDAS Ltd. (www.ledas.com), an independent software provider of computational components for PLM and ERP, announces launch of new licensing policy of its 2D and 3D geometric solvers for non-commercial Academic and Educational organizations. The new policy is based on issuing free LGS License in exchange to academic publications, which researchers publish. Free Academic Licensing approach gives unique opportunity for researches and students to access parameterization technology.
The first team to exploit benefits of new licensing policy is PRECISE (Purdue Research and Education Center for Information Sciences in Engineering), in the School Mechanical Engineering and also a part of the Discovery Park of Purdue University, Indiana, USA.
«As a part of my ongoing research, I need to develop a simple sketcher that uses a geometric constraint solver. I recently came across one of you products, the LGS 2D solver, we are unable to purchase the LGS 2D at the listed commercial rates, so an Academic License is good opportunity for us» says Srikanth Devanathan, PhD student in Mechanical Engineering at Purdue University.
About the LGS family solvers
LGS 2D/3D is a cross-platform software. It is set of libraries that runs under all Windows, Linux, *BSD, AIX and other OS. Being written itself in C++, LGS has a C-based API that allows one to integrate it into a broad range of software applications (even written not in C/C++).
A sample test application for LGS called Lege’n’d is also available as part of the Evaluation version of LGS 2D/3D. They were created with the Open CASCADE open-source framework. The Lege’n’d 2D and 3D applications can be used to test the entire functionality of the LGS 3D without the need to integrate the solver into other software packages. A set of representative examples for Lege’n’d 2D/3D is also supplied.
LEDAS Geometric Solvers 2D/3D support creation and modification of the geometric models by means of (explicit or implicit) constraints. Typical geometric objects are points, lines, circles, planes, cylinders, spheres, arbitrary curves, surfaces and swept surfaces. Objects can be fixed in an absolute coordinate system or relative to each other (the latter feature is provided by the so-called rigid sets of objects). Set of geometric constraints includes logical constraints between geometric entities (like coincidence, parallelism, tangency, etc.) and dimensional constraints (that specify the required values for given distances, angles or radii). LGS moves and rotates objects to the positions where all constraints are satisfied by performing minimal transformations of initial configuration. It also renders standard CAD functions - ‘move under constraints’ and diagnostics of over- and under-defined parts of a model.
LGS 2D/3D are based on the Ledas’ state-of-the-art engine provide affordable solution for those who need a strong variational and constraint-based functionality in CAD, modeling, or engineering software. Through the scalable architecture of LGS, variational and parametric techniques become available in a wide range of the products including desktop CAD/CAM/CAE, and object modeling tools, assembly design and analysis and others.
PRECISE Team research works lie at the intersection of design, shape analysis, and information sciences. The increase in 3D data in engineering, biology and medicine has given rise to many new problems for 3D content based shape search. We focus on developing new representations for (3d and 2d) shapes for engineering and proteomics. We also develop new interaction paradigms, interfaces for querying, interacting, orienteering, and navigating intelligently. Another area of focus is computer support for early design and configuration. PRECISE web site is http://engineering.purdue.edu/precise.
