Daylighting simulations with BSDFs

Ocean 2016 Release 5 has been made available last week. It brings a new feature, the Igloo Matrix BRDF model, which allows using data from the LBNL WINDOW software (IGDB database). We have tested it on a 3D office model, with a double glazing unit (DGU) window comprising a high performance solar control coating. The […]

Ocean 2016 is available!

After a long development period, Eclat-Digital is glad to announce the release of Ocean 2016!

Ocean 2015 – FPD rendering

Ocean 2015 allows modelling highly complex light sources such as flat panel displays (FPD) from measured data

Ocean 2015 – Colorimetry

Ocean 2015 has several new groundbreaking features for working with colors XYZ color input It is now possible to set a material color to XYZ instead of RGB. This feature exists in other renderers, but implementations always suffer from either of these drawbacks: The XYZ value is converted to RGB and thus is always clipped […]

Ocean 2015 – Spectral imagery

Spectral rendering Ocean 2014 could already render spectral images with the “spectralbox” sensor type. In Ocean 2015, we added three powerful new features for working with spectral renders Spectral EXR file format When saving a spectral render to the EXR format, Ocean now embeds metadata so that the wavelength information is kept. This defines a […]

Ocean 2015 – Graphical User Interface

Ocean 2015 is now available. This major upgrade is packed with a lot of new features and improvements!

Brewster angle simulation

Brewster angle When a beam of light reflects on a dielectric material such as glass under a special angle of incidence, named the Brewster angle, the reflected beam is linearly polarized along the plane of incidence. If this beam hits a second glass sheet under the same angle, but rotated by 90° along the beam, […]

Ocean 2014

Eclat-Digital is pleased to announce the official release of Ocean 2014, after several months of intensive development!

Modelling the Memorial

A real project featuring highly complex glass structures, the Memorial to the Abolition of Slavery in Nantes, France, was modeled and simulated with Ocean.

Support for IES light sources

The light source system has been completely redesigned in Ocean 2014. It fully supports IES profiles, an industry standard for describing light sources

Complex Light Sources – Ocean 2014 feature

Introduction Ocean 2013 was developed mainly for outdoor scenes, with complex environment lighting models. It is able to use analytic polarized sky models, as well as high resolution, high dynamic range images, to light the scene, making it possible to simulate any outdoor weather conditions. Ocean 2013 is able to simulate artificial lighting as well, […]

Simulating the “Death Ray”

In this post, we tried to simulate the "Death Ray" effect happening with concave reflective facades, such as the 20th, Fenchurch street "Walkie Talkie" tower in London.

Birefringence of tempered glass

Ocean can simulate very complex optical phenomena, such as non-uniform birefringence in tempered architectural glass.

Comparing glazings

Using Ocean for building design The Ocean software can generate accurate images of complex materials such as coated glass. This makes it an interesting tool for building design, as it is possible to predict the aspect of the project depending on used materials, by doing virtual mock-ups, without any construction cost. Many questions can be […]

Support for integrated Thin Films

Starting from version 1.4, Ocean supports thin film calculations. This alternative to tabulated reflection/transmission data unlocks a lot of possibilities!

Color tolerances of car paints

Introduction Some industrial processes produce variable colors, that are adjusted to match a given target. The target is not only a single color value, it must provide tolerances for the color coordinates, in which the product can be considered as good. Choosing optimal color tolerances is a difficult task : if they are too large, […]

Daylighting simulation

In this example, we demonstrate the use of Ocean for performing precise simulation of building day-lighting designs

Audi R8

Images of an Audi R8, rendered with spectral measures of car paints

Visualization of car windshields

Custom materials with angle dependent tabulated spectra allow modelling complex materials such as car paints or athermic windshields

Featuring light polarization

Light polarization effects cannot be ignored without introducing significant errors in optical simulations and renderings

Spectral rendering

Full spectral light transfer calculations are mandatory for engineering light simulation tools, and especially for colorimetric predictions.

Rendering metamerism

Ocean computes exact colorimetry, thanks to its full spectral core. It is well suited for modelling complex colorimetry phenomena such as metamerism.

Simulating tempering distortions

A simple example on how to use Ocean for evaluating the visual impact of glass distortion in architecture, depending on glass type.
