A new optimization toolbox in SPEOS CAA V5 Based to improve lit appearance simulations

OPTIS, the world leading 3D lighting technology provider announced for 2006 some major new product capabilities. After having being the first to include the lit appearance in its simulation process and to integrate CAD software, OPTIS has now added the possibility of optimizing design through the use of several very innovative tools.

Here the optimization of a car tail-lamp design clearly illustrates the advantages of these new SPEOS technology tools. Thanks to the fact that the software is integrated in CATIA V5, optics and mechanics can be treated together. Thus opto-mechanics can be optimized at the same time. Moreover new developments allow designers to improve the optics parts of a system using very efficient tools. It is possible to automatically generate optical shapes (parabola, conics…) and to create assemblies made of several optical elements.

The software is able to generate and to automatically position a set of optics. For instance a car tail-lamp is made of more than 100 optical pillows. The optical feature used by SPEOS CAA V5 Based will drive, in only one run, the generation of these 100 pillows taking into account all the optical requirements. Position and orientation will automatically follow the propagation rules the designer sets. Thus, optical knowledge is encapsulated in this optical feature and can be applied to complex system design.

In this way, photometric simulations (SPEOS Light Modeling - photometry) can be performed very rapidly. Then the analysis of the light propagation in the system and the photo-realism simulation taking into account human vision properties (SPEOS Visual Ergonomics) can be done from the optimized design.

Moreover calculations can now be launched on a PC cluster. This drastically reduces the calculation time. In this way lit appearance of a tail-lamp for instance can be obtained very rapidly with a high level of realism. As a final result, a tail lamp can be simulated to give both lit and unlit appearance. All the small optical pillows of the tail-lamp (see below) have been very easily designed and optimized thanks to these very innovative tools. Moreover, exterior conditions such as night, day and weather can be included in the simulation to increase the level of realism.

It is also possible to easily modify the kind of bulbs and lenses to multiply "what-if" scenarios. For example you can easily change the kind of lenses or bulbs as below.

Design process using automatic features.

Many benefits come with these unique SPEOS Technology capabilities. Firstly, automatic "optical features" bring high value to the design product process. If you consider a 100-pillow tail-lamp, without the automatic optical feature, you needed to design each pillow one after one. It meant that you spent a lot of time doing repetitive tasks and adjusting optical elements.

With the new automatic "optical features", the design and the product development lifecycle are drastically shortened. Time to market is improved. Moreover optical "features" allows know-how to be encapsulated in automatic routines. Then they can be saved and diffused into the company. Not only will optical specialists save a lot of engineering time but they will also share their expertise internally.

Secondly, distributed calculation (PC cluster) divides the simulation time. It offers more power to use the optimization tools such as the "optical features" because more and more calculations can be run. SPEOS software can compute more and more complex systems and Amber Bulb Lens Silver Bulb increase the degree of realism of the simulations. It becomes easier to virtually validate prototypes without building physical ones.

OPTIS is the first company to provide light simulation solutions fully based on a physical model inside CAD/CAM software. Specialized in optics and software development, OPTIS has developed innovative solutions since it was founded in 1989. SPEOS, SOLSTIS and LIGHT cater to the needs of industry, research and architecture and are used in more than 35 countries throughout the world.

SPEOS addresses industrial markets and integrates photometry, colorimetry, lighting and photo-realism capabilities fully based on physics. Its live-measured library of material, sources and sensors provides highly realistic virtual prototypes, giving light information. Its unique eye-vision model provides answers about the perception of a 3D environment often needed for ergonomics and safety applications. SOLSTIS is dedicated to research laboratories in the fields of lasers, telecommunications and optics. LIGHT computes the illumination level inside any 3D architecture scene and brings it exact light levels, aspects and colours. OPTIS is the first company in the world to fully provide solutions for industrial needs for light information.

Its unique colorimetry, ergonomics, and lighting solutions set a new precedent in digital mock-up. In 2002, OPTIS was awarded Gold Product status by SolidWorks Corporation for its integrated light simulation, OPTISWORKS.
