- Parameters:
min
- the lowest value in this tuple after clampingmax
- the highest value in this tuple after clamping
public final void clamp(float min, float max, Tuple3f t)

- the highest value in the tuple after clampingt
- the source tuple, which will not be modified
public final void clampMax(float max)
Clamps the maximum value of this tuple to the max parameter.
- Parameters:
max
- the highest value in the tuple after clamping
public final void clampMax(float max, Tuple3f t)
Clamps the maximum value of the tuple parameter to the max parameter and places the values into this tuple.
- Parameters:

- Parameters:
min
- the lowest value in the tuple after clamping
public boolean epsilonEquals(Tuple3f t1, float 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)].
- Parameters:
t1
- the tuple to be compared to this tupleepsilon
- the threshold value
public boolean equals(Tuple3f t1)
Returns true if all of the data members of Tuple3f t1 are equal to the corresponding data members in this
- Parameters:
t1
- the vector with which the comparison is made.
public final void get(Tuple3f t)
Gets the value of this tuple and copies the values into the Tuple3f.
- Parameters:
t
- Tuple3f 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[].
- Parameters:
public int hashCode()
Returns a hash number based on the data values in this object. Two different Tuple3f objects with identical data values (ie, returns true for equals(Tuple3f) ) will return the same hash number. Two vectors with different data members may return the same hash value, although this is not likely.
