In France, Optis Group of La Farlède, a software editor and scientific simulator of light and human vision within virtual reality, has acquired SimplySim SAS of Sophia Antipolis, a software provider for rendering, simulation and robotics. The SimplySim technology will enable Optis to integrate its real-time product portfolio into a 3-D platform that is compatible with multiphysics engines, providing greater realism in global simulation. Adding physics-based rendering to a user-friendly platform will allow engineers and designers to make quick, accurate decisions while inside a virtual environment around a fully digital mock-up, according to Optis. The SimplySims SimplyCube software is used to develop virtual environments by applying physics behavior to each entity, generating the realistic behavior of an object.
