Ocean 2015 – Spectral imagery

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 new HDR spectral image format.
We are in contact with companies and academic labs working with spectral images, to establish a standard with this format. It is fully compatible with the OpenEXR open source library for reading and writing, and we will issue a detailed article on how to use it in your code. In the mean time, feel free to ask us for information on how to implement it.

Spectral renders can be displayed in gray scale by selecting an individual wavelength

Easy selection of wavelength channels

Each rendered wavelength channel is now displayed in a user friendly form, rather than in a cryptic channel name.

Spectrometry toolbox

This new toolbox is dedicated to spectral renders, and works similarly to the photometry and colorimetry tools. The pipet allows selecting a single pixel or a rectangular region. Then, the corresponding spectrum is displayed in a table and graphically. Tabulated data can be copied to the clipboard, or saved to a text file.

Spectral image input

The new spectral EXR image format can be used as regular images in Ocean objects, such as materials. This allows a wide range of applications, such as spectral textures, environments and emitter distribution, and much more.

Other Ocean 2015 features

New features will be presented this fall in a weekly “feature higlight” update. In the meantime, you may discover them by downloading Ocean 2015
