|
Modifier and Type | Method | 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.
|
Vector |
subtract(Vector v) |
Computes the difference between this vector and the specified vector
|
String |
toString() |
