This is a physically accurate procedural water shader for Blender that includes:

• Both refracted and reflected caustics, including dispersion for refracted calculated using Snell's Law, that is generated by the actual displacement and undulation of the water surface.

  
  

  
  

• Foam with adjustable coverage and scale that also interacts with objects, plus a toggle for thin film interference using the pioneering work of Doctor Robert Moerland.

• Volumetric absorption and scattering that scales in world space meters with the size of the object along the global Z axis (deeper objects show greater absorption and extinction of light with respect to red, green, and blue attenuation rates, for instance).

  
  

• Surface refracted dispersion using the Sellmeier Equation to calculate the IOR for water per wavelength of light.

  
  

  
  

• Multilayered displacement that blends a number of different procedural frequencies for realistic wave and swell generation.
