Detailed Description

Policy to keep normals unnormalized.

Using this policy will keep direction vectors and normals at their original length. You can do this for precision reasons, for speed issues, or any other reason that is yours. However, the maths will still be correct, because the implementations will know of this unnormalized vectors, and will correct with extra factors where necessary. But, these corrections can sometimes be faster than using normalized vectors for start, because they often can avoid the square root.

Don't normalize normals we want to keep unnormalized!

:) this is a noop.

divideByNorm()

template<typename ValueType, typename VectorType>

static ValueType lass::prim::Unnormalized::divideByNorm ( ValueType iValue, const VectorType & iNormObject )

inlinestatic

Returns

iValue divided by the norm of iNormObject

divideBySquaredNorm()

template<typename ValueType, typename VectorType>

static ValueType lass::prim::Unnormalized::divideBySquaredNorm ( ValueType iValue, const VectorType & iNormObject )

inlinestatic

Returns

iValue divided by the squared norm of iNormObject
