fast_normalize

Returns a vector in the same direction as p but with a length of 1. fast_normalize is computed as: p * rsqrt((half)(pow(p.x, 2) + pow(p.y, 2) + ...)).

return_t fast_normalize(F p)

1. Returns a vector in the same direction as p but with a length of 1. fast_normalize is computed as: `p * rsqrt((half)(pow(p.x, 2) + pow(p.y, 2) + ...))`.
   Parameters:
   • F p
