> URL: https://issues.apache.org/jira/browse/GEOMETRY-26
> Project: Apache Commons Geometry
> Issue Type: Wish
> Reporter: Matt Juntunen
> Priority: Minor
>
> I propose adding a {{safeNormalize}} method to the {{Vector}} classes that
> will return null instead throwing an exception when attempting to normalize.
> The rationale for this is that
> in some algorithms, different actions may need to be taken depending on
> whether or not a vector can be normalized. It is inefficient to calculate the
> norm, determine if it is valid (zero, NaN, or infinite), and then calculate
> it again in the {{normalize}} method to perform the normalization. One
> approach to avoid this is to simply call {{normalize}} and then catch any
> exceptions that are thrown on failure (this is what
> {{QuaternionRotation.getAxis()}} does). However, I think having a null check
> will produce cleaner code.
