Ocean™ 2022 is now available !

This 2022 Ocean™ version integrates new features and improvements regarding user experience and operating tools. Moreover, this version marks a turning point in the development of the software due to a refactoring of the Ocean™ architecture, to bring more flexibility in future developments.

As the licensing system has been impacted by these changes, some user actions are required to detect the licence dongle. Find out the basic steps to follow in the documentation.

New features :

  • Refactoring
  • Human vision
  • Abbe Number
  • Spectral to Custom
  • Rhino Plugin

Refactoring

Ocean™ has been completely reshaped compared to its 2021 version. If the rendering core code has not been rewritten, the software architecture itself has been completely redesigned.

The main reason for this code refactoring is to bring a more modular approach allowing more flexibility in our future development, this means facilitate the creation of new plugins while making it easier to maintain the software. This modular approach is already being tested internally for one of our customers and will soon be the subject of a full blog post.

Human Vision

Human vision module is an Ocean™ 2022 brand-new feature. This module, available as a bunch of post-processing filters, can reproduce several properties of the human eyes. It can be used for projects in automotive to evaluate the perception of interior and exterior light sources such as screens, dashboard lights or streetlights (example below).

The first Human vision post-processing filter, is Drago filter, a log-based tone-mapping. It aims at reinforcing the realistic aspect of a given scene that would appear differently in real life compared to a simulation displayed on a screen.

More advanced features on Human Vision are in development, such as :

  • Difference between night (grey) and day (color) vision
  • Eye sensitivity that changes with age
  • Time adaptation to change of luminosity
  • Glare effect due to pupil and cornea (example bellow)

Abbe Number

We have added a new type of spectrum: “Abbe Number Spectrum”.

This new node is particularly intended for those who wish to be able to define a type of glass, without having a measurement of the refractive index. Thanks to the parameters and Ocean™ will calculate the variation of the refractive index with the wavelength. This node is mainly used in the definition of the ‘n’ spectrum of dielectric functions.

Spectral to Custom

We introduce here a new node “Spectral to Custom” that can change the workflow of the most advanced Ocean™ users by bringing real flexibility on the formats of the results.

As Ocean™ is a spectral simulation software, whatever the format of your simulation result, the core calculation is done on the continuous spectrum. By default, the OCRAW format is defined by the ‘Sensor’ (CIE XYZ, Energy, Spectral boxes, …) and the analysis will be done in RGB Image or Channel Image. Thanks to the “Spectral to Custom” post-processing node combined with a “Spectral boxes” sensor, you can perform the conversion in post-processing, on the fly, without modification : Spectral to “what you need” : CIE XYZ, Energy, Custom functions, …

No need to run the simulations again by changing the type of sensor to condition your output format, a single spectral simulation is enough, the conversion is done in post-processing.

For example, it is possible to switch from an aesthetic rendering (CIE XYZ) to an energy quantization (Energy), or to vary the ‘Y’ function to reproduce the behavior of human vision: age, scotopic/mesopic/photopic vision, color blindness or other.

Rhino Plugin

In Ocean™ 2022, the Rhino plugin has been updated with bugfixes and new features. The plugin is compatible with Rhino 6 and 7 (support for Rhino 5 has ended).

Once installed, you’ll be able to retrieve the “Ocean™ Exporter” to ease the process of getting a scene from Rhinoceros 3D to Ocean™.

Moreover, a new panel is now available as a beta version, allowing to manage the translation between Rhino views and Ocean™ instruments
