Modelling optical performance of devices in conventional CAD packages has proved either impossible or extremely time-consuming. However, managing light and lit appearance are crucial for lighting systems, style signature and human machine interfaces.

OPTIS has announced that its 3D Textures application will soon be available into SPEOS CAA V5 Based, the CATIA V5 integrated version of OPTIS’s SPEOS light simulation software. SPEOS enables engineering designers to model complex integrated mechanical and optical engineering tasks seamlessly within CATIA V5.

Using 3D Textures For SPEOS CAA V5 Based, a designer can easily create tens of millions of modelled points on surfaces, directly inside CATIA V5, in view to manage the way light is propagated and comes to the final user’s eye.

With the integration of LED sources in more and more systems such automotive tail lamps, luminaire design, lit buttons and backlights in electronics including PDAs and mobile phones, it becomes necessary to generate 3D Textures motifs applied on complex compound surfaces.

SPEOS 3D Textures enables a 3D model to include tens of millions of patterns thanks to a memory requirement optimization (150Mb needed for 1 million patterns), a rapid loading time and fast simulation time (16min for 4 million patterns). It also offers fully optimised multithreaded and 64bit operation, which other packages cannot match.

3D Textures For SPEOS CAA V5 Based will offer advanced optical design capabilities, including modelling CAD patterns onto any possible CAD shape and surface and modelling based on mixing diverse materials of construction.

With this unique 3D Textures function, SPEOS CAA V5 Based will enable both improved design functionality and time-saving in challenging applications such as modelling backlit displays, and the latest designs of automotive lights.
