  julia_fractal { 4D_VECTOR [JF_ITEMS] [OBJECT_MODIFIERS] }

JF_ITEMS:
  [ALGEBRA_ITEM] & [max_iteration INT] & [precision FLOAT] 
    & [slice V4_NORMAL, F_DISTANCE]

ALGEBRA_ITEM:
  quaternion [QUATER_FUNCTION] | hypercomplex [HYPER_FUNCTION]

QUATER_FUNCTION:
  sqr | cube

HYPER_FUNCTION:
  sqr | cube | exp | reciprocal | sin | asin | sinh | asinh 
    | cos | acos | cosh | acosh | tan | atan | tanh | atanh 
    | ln | pwr (FLOAT,FLOAT)
