Optimised vector and quaternion normalisations adding fast inverse square root (!32015) · Merge requests · Rafał Mikrut / godot

Rafał Mikrut requested to merge github/fork/puthre/fast_inv_sqrt2 into master Sep 06, 2019

Created by: puthre

I've added Math::fast_inv_sqrt that computes 1/sqrt(x) almost 5 times faster and modified the Vector2, Vector3 and Quat classes to make use of it for normalization. Normalizations should be now A LOT faster. See https://en.wikipedia.org/wiki/Fast_inverse_square_root
