float4::AngleBetween4

Syntax

float float4::AngleBetween4(const float4 &other) const; [10 lines of code]

Returns the angle between this vector and the specified vector, in radians.

Note
This function takes into account that this vector or the other vector can be unnormalized, and normalizes the computations.
