Object types

Various object types are editable in the Ocean graphical user interface. They can be selected and created in the Objects toolbox



Instruments are the “probes” in your scene. They gather light and generate the result images. No simulation can be run without an instrument.

You may define multiple instruments, for instance several cameras. The active instrument for the simulation may be chosen in the render settings.

Materials control the optical properties of geometry surfaces, such as reflectance, glossiness, roughness, transparency or light emittance.

When exporting the scene from a CAD software, each surface is given a material name. Some basic materials (generally diffuse) with the matching names are created in the process. After loading the scene in Ocean, you can edit these materials, to give them more realistic properties. You can also link them to existing materials, or import previously exported Ocean materials.

Environments are light sources located at infinity. They describe light coming from outside your scene, such as daylight. The other type of light source in Ocean is a geometry object whose material has light emission properties.

You may define multiple environments, for instance several weather conditions for daylight. The active environment for the simulation may be chosen in the render settings.

Media control the optical properties of volumes, such as refractive index and light extinction.

To fill a closed geometry volume with a medium, the geometry must be assigned a material, and this material must define that the surface marks the entrance to a different medium. Please read modelling volumes for more details

BSDF A BSDF or Bidirectional scattering distribution function is a general representation of the reflective and transmissive optical properties of surfaces.

The terms BRDF and BTDF are often used for reflection and transmission. BSDF is a generic term for both.

Spectrum A spectrum element describes a wavelength-dependent parameter. They are used for describing light sources, material properties, instrument sensivities, …

Images allow loading image files for used in various object properties, such as surface textures.

A Setup is an object which defines the main simulation parameters.

Defining multiple setup objects allows storing various simulation scenarii and recalling them quickly.

Layer sets

Layer set

A Layer set is an object which stores layer visibility and materials overrides.

Defining multiple layer set objects allows storing various scene configurations and recalling them quickly.
