Function Synopsis

s = vrml_PointLight (...)

Help text

  s = vrml_PointLight (...)   - Vrml PointLight node

  s is a string of the form :
  ------------------------------------------------------------------
  PointLight { 
    exposedField SFFloat ambientIntensity  0       ## [0,1]
    exposedField SFVec3f attenuation       1 0 0   ## [0,inf)
    exposedField SFColor color             1 1 1   ## [0,1]
    exposedField SFFloat intensity         1       ## [0,1]
    exposedField SFVec3f location          0 0 0   ## (-inf,inf)
    exposedField SFBool  on                TRUE 
    exposedField SFFloat radius            100     ## [0,inf)
  }
