VectorUtil::VectorCot

Fast cotangent of angle between two vectors (_do not have to be normalized unit vectors_).

Windows

MacOS

Linux

Syntax

namespace VectorUtil
{
    template<typename RealType>
    RealType VectorUtil::VectorCot
    (
        const FVector3< RealType > & V1,
        const FVector3< RealType > & V2
    )
}

Remarks

Fast cotangent of angle between two vectors (do not have to be normalized unit vectors). cot = cos/sin, both of which can be computed from vector identities

Returns

cotangent of angle between V1 and V2, or zero if result would be unstable (eg infinity)
