Subject [jira] [Updated] (GEOMETRY-9) New Euclidean Vector Methods
Date Mon, 03 Sep 2018 04:19:00 GMT
```
[ https://issues.apache.org/jira/browse/GEOMETRY-9?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Matt Juntunen updated GEOMETRY-9:
---------------------------------
Description:
We should add some more methods to the Euclidean vector classes for user convenience and algorithm
clarity.
# length() – more intuitive alias for getNorm()
# project(Vector) – returns the current vector projected onto the given vector
# static project(Vector, Vector) – static version of project
# reject(Vector) – returns the current vector projected onto the plane whose normal is
passed to the method (vec equals vec.project(v) + vec.reject(v))
# static reject(Vector, Vector) – static version of reject
# lerp(Vector, double) – linear interpolation between the current vector and the given
one
# static lerp(Vector, Vector, double) – static version of lerp
# withLength(double) – returns the current vector with the given length. This is equivalent
to vector.normalize().scalarMultiply(x) but without the intermediate vector.
