|
Constructor and Description |
---|
Vector(float x, float y, float z)
Creates a new Vector
|
Modifier and Type | Method and Description |
---|---|
Vector |
cross(Matrix by)
Computes the cross product of this vector and the specified matrix
|
Vector |
cross(Vector with)
Computes the cross product of this vector and the specified vector
|
float |
dot(Vector with)
Computes the dot product of this vector with the specified vector
|
boolean |
equals(Object obj) |
float |
get(int index)
Gets the value from a coordinate of the vector
|
int |
hashCode()
Calculates the hashcode using the values.
|
float |
length()
Computes the length of this vector
Note: If you are working with raw vectors from PDF, be careful - the Z axis will generally be set to 1. |
float |
lengthSquared()
Computes the length squared of this vector.
|
Vector |
multiply(float by)
Multiplies the vector by a scalar
|
Vector |
normalize()
Normalizes the vector (i.e. returns the unit vector in the same orientation as this vector)
|
Vector |
subtract(Vector v)
Computes the difference between this vector and the specified vector
|
String |
toString() |
