Water in a Glass
For simulating water im a glass, we need a transparent material with an index of refraction ior = 1.33.
material{
  texture{
    pigment{ rgbf<.93,.95,.98,0.825>*0.99}
    finish { ambient 0.0 diffuse 0.15
             reflection{0.1,0.1 fresnel_on}
             specular 0.6 roughness 0.005
             conserve_energy
           } // end finish
  } // end of texture

  interior{ ior 1.33
             fade_power 1001
             fade_distance 0.5
             fade_color <0.8,0.8,0.8>
             caustics 0.16
   } // end of interior
 } // end of material
//-----------------------------------------


Water in a Glass
A material for water
To get this shape with a wavy top side, we intersect the above shape with the same shape, but somewhat wider and lower with this material and the additional normal in texture:
     normal{ ripples 1.15
             scale 0.0125
             turbulence 0.3
             translate<-0.05,0,0>
             rotate<0,-20,0>
           } // end normal

//-----------------------------------------





Water in a Glass
A material for water with wavy top side
All we got to do now: Adding this to a simple glass!
(Glass material has an higher IOR (~1.5) and a little bit different color).
