Ocean Optics section.

Psunami Water has many parameters to control the behavior of water. The 'Ocean Optics' section controls how light in your scene will affect the water.

In real oceans, coloration is determined by two properties of light. One property is the direct light color reflecting from the surface.

The other property is 'upwelling', or light emanating from below the water surface. Psunami's 'Ocean Optics' control the color and intensity of that upwelling light.

An underwater scene colored with a blue 'Water Color'.

Primary Waves section.

In Psunami and the real world, waves are generated by wind. The 'Primary Waves' section lets you control the speed, direction, density, detail, smoothness, and scaling of the waves.

For instance, 'Ocean Complexity' and 'Grid Size' options let you choose the level of detail used to calculate the ocean surface. Higher detail will increase the realism.

'Wind' parameters control the direction of the wind in your scene. Because Psunami is based on real-world physics, the wind speed and direction determine its wave speed and direction. High 'Wind Speed' values generate faster-moving, more violent waves (below, left). Lower 'Wind Speed' produces slow, gentler waves. (below, right)

Gee, that's Swells section.

Swells are very large and more stable waves. In real life, they're caused by distant phenomena like storms and earthquakes.

In Psunami, the 'Swells' section works separately from other wave controls, like the 'Primary Waves'. You can add two 'Swell' groups to your ocean surface. Use the 'Swell' parameters control their direction, height, length, roughness and periodicity.

A default Swell, with Primary Waves turned off.		'Swell Height' increased to the swell, measured in meters.
'Swell Length' set low to create short, choppy swells.		A high 'Swell Roughness' adds noise and irregularity.
