 Description  « Hide
Vec4, Matrix and Quaternion cache certain computations (e.g. length, normal, inverse). This behavior violates the immutability contract (these classes are immutable), and causes a bottleneck in the constructor (cached values are initialized).

Vec4, Quaternion and Matrix now place the responsibility of caching computations on the client. The only remaining "cached" value in each class is the hash-code.
