Optical simulations using ray tracing technology

light quantification eclat digital

Lighting simulation

Ocean™ provides high-accuracy illumination calculations combined with state-of-the-art algorithms that enable high computation speed and efficient memory use. It allows the use of fully detailed CAD models with several million polygons, reducing the need to make simplified models for light engineering.

color prediction ocean

Color prediction

Unlike most computer graphics programs, Ocean™ features a polarised full-spectral lighting algorithm, enabling the highest level of accuracy for lighting simulations. Computing interactions between materials and light is performed by retaining all the information which could have an impact on final product colors.

complex light sources oceanTM

Material & light modeling

Ocean™ models a very broad range of surfaces and light sources just by using your lab measurements. Metallic car paint, coated glass, brushed metals, dyed plastics, LCD screens and LED lamps are just a few examples of objects which are traditionally difficult to model with classical 3D software, and easy with Ocean™.

Q&A

You need a full-spectral solution like Ocean™ when you need to accurately simulate materials or products or to quantify the light repartition. The software allows the integration of all the complexity of various data: fluorescence spectra, spiked data, IR/UV spectra …
Not at all. Even if Ocean™ is said to be “by engineers, for engineers”, the interface is meant to be open and user-friendly for any user profile, scientific or not. Moreover, Eclat Digital provides software training when acquiring an Ocean™ licence.
Ocean™ has been designed and optimised for very fast computing times: from a few minutes to a few hours, depending on the complexity and the computer.
Ocean™ can be fully utilised on a simple laptop or on a computer farm. Bigger is faster!

No, Ocean™ is a CPU-based solution, the software runs on any computer, because they all have a processor.

Ocean™ is a stand-alone software that manages all aspects of the simulation : data, organizations, rendering engine and analysis. As for the data preparation (3D, tabulated data, …) must be prepared upstream in specialized software. We have developed connectors to facilitate communication with certain software.
