  spheresize = 1000,
  material = diffuse(color = "#ccff00")
)

Arguments

depth

Default '-1'. Depth of the surface.

spheresize

Default '1000'. Radius of the sphere representing the surface.

material

Default diffuse with 'color= "#ccff00"'.The material, called from one of the material functions diffuse, metal, or dielectric.

color

Default '#ccff00'. The color of the sphere. Can be either a hexadecimal code, or a numeric rgb vector listing three intensities between '0' and '1'.

Value
