Constructor Detail

RVector4d

public RVector4d()

Constructs and initializes a RVector4d to (0,0,0,0).

RVector4d

public RVector4d(RVector4d vector)

Constructs and initializes a RVector4d from the specified RVector4d.

Parameters:

vector - the RVector4d containing the initialization x y z w data

RVector4d

public RVector4d(javax.vecmath.Vector4d vector)

Constructs and initializes a RVector4d from the specified Vector4d.

Parameters:

vector - the Vector4d containing the initialization x y z w data

RVector4d

public RVector4d(double[] vector)

RVector4d

public RVector4d(double x,
                 double y,
                 double z,
                 double w)

Constructs and initializes a RVector4d from the specified xyzw coordinates.

Parameters:

x - the x coordinate

y - the y coordinate

z - the z coordinate

w - the w coordinate

Method Detail

printf

public void printf()

Prints to standard out

printf

public void printf(java.lang.String format)

Prints to standard out according to the format string.

The format specifiers for numeric types have the following syntax:

 %[width][.precision]conversion
 

• The optional width is a non-negative decimal integer indicating the minimum number of characters to be written to the output.
• The optional precision is a non-negative decimal integer usually used to restrict the number of characters. The specific behavior depends on the conversion.
• The required conversion is a character indicating how the argument should be formatted. The set of valid conversions for a given argument depends on the argument's data type.

Example:
v.printf("%5.3f");

Parameters:

format - The format string

See Also:

PrintStream.format(java.lang.String, java.lang.Object[])

printf

public void printf(java.io.PrintStream out)

Prints to PrintStream

Parameters:

out - The PrintStream object.

printf

public void printf(java.io.PrintStream out,
                   java.lang.String format)

Prints to PrintStream according to the format string

Parameters:

out - The PrintStream object.

format - The format string.

toString

public java.lang.String toString()

Returns a string that contains the values of this RVector.

Overrides:

toString in class javax.vecmath.Tuple4d

Returns:

The string.

toString

public java.lang.String toString(java.lang.String format)

Parameters:

format - The format string

Returns:

The string
