SafeNormalize

template<typename T>
inline T SafeNormalize(

const T &v,

const T &fallback = T(),

)

Safely normalizes a vector with fallback for zero-length vectors.

Template Parameters:

T – Vector type that supports LengthSq(), multiplication, and InvSqrt()

Parameters:

• v – [in] Vector to normalize

• fallback – [in] Fallback vector to return if v has zero length (default: default-constructed T)

Returns:

Normalized vector if length > 0, fallback vector otherwise
