OPTIS has been a Dassault Systèmes Software Partner since 2002 providing light and vision simulation capabilities fully based on a physical model to CATIA V5 users. Integration in CATIA V5 gives users of OPTIS solutions a : Highly user friendly interface Advanced light and optical simulation directly integrated in their overall product design process. Physically correct computer-generated images suitable for decision making Time savings of up to 80% Reduced need for physical prototypes The advanced functionalites needed to take their innovations further Direct import of material appearance into their simulation Ergonomics studies taking into account human visual perception visualisation of light, color and material effects in a 3D immersive environment OPTIS has benefited from the partnership in the following ways: - development of the automotive and aeronautic sectors - access to DS' international distribution network - marketing and communications synergies SPEOS 2012 is the core technology behind OPTIS’ family of light simulation software and is a stand-alone software package for users without a CAD platform. With twenty years of practical application, SPEOS is the most full featured and realistic tool to create, analyze, and virtually validate innovative lighting systems.
