public boolean epsilonEquals(Tuple4d t1, double epsilon)
Returns true if the L-infinite distance between this tuple and tuple t1 is less than or equal to the epsilon parameter, otherwise returns false. The L-infinite distance is equal to MAX[abs(x1-x2), abs(y1-y2), abs(z1-z2), abs(w1-w2)].
- Parameters:
t1
- the tuple to be compared to this tupleepsilon
- the threshold value
public boolean equals(Tuple4d t1)
Returns true if all of the data members of Tuple4d t1 are equal to the corresponding data members in this

t1
- the vector with which the comparison is made.
public final void get(Tuple4d t)
Gets the value of this tuple and copies the values into the Tuple4d.
- Parameters:
t
- Tuple4d object into which that values of this object are copied
public final void get(t[] )
Copies the value of the elements of this tuple into the array t[].
