adjustForSidednessAgreement()

void ph::lta::SidednessAgreement::adjustForSidednessAgreement ( SurfaceHit & X ) const

inline

isBackHemisphere()

bool ph::lta::SidednessAgreement::isBackHemisphere ( const SurfaceHit & X, const math::Vector3R & vec ) const

inline

Returns

Whether vec is under the back facing hemisphere given current policy.

Note

isFrontHemisphere() == !isBackHemisphere() is not necessary true. Consider the case where one of the vectors is perpendicular to the normal, it could theoretically belong to both hemisphere; to eliminate the ambiguity, the test is exclusive and returns false in this case.

isFrontHemisphere()

bool ph::lta::SidednessAgreement::isFrontHemisphere ( const SurfaceHit & X, const math::Vector3R & vec ) const

inline

Returns

Whether vec is under the front facing hemisphere given current policy.

Note

isFrontHemisphere() == !isBackHemisphere() is not necessary true. Consider the case where one of the vectors is perpendicular to the normal, it could theoretically belong to both hemisphere; to eliminate the ambiguity, the test is exclusive and returns false in this case.

isOppositeHemisphere()

bool ph::lta::SidednessAgreement::isOppositeHemisphere ( const SurfaceHit & X, const math::Vector3R & vecA, const math::Vector3R & vecB ) const

inline

Returns

Whether vecA and vecB are under the opposite hemisphere given current policy.

Note

isOppositeHemisphere() == !isSameHemisphere() is not necessary true. Consider the case where one of the vectors is perpendicular to the normal, it could theoretically belong to both hemisphere; to eliminate the ambiguity, the test is exclusive and returns false in this case.

isSameHemisphere()

bool ph::lta::SidednessAgreement::isSameHemisphere ( const SurfaceHit & X, const math::Vector3R & vecA, const math::Vector3R & vecB ) const

inline

Returns

Whether vecA and vecB are under the same hemisphere given current policy.

Note

isSameHemisphere() == !isOppositeHemisphere() is not necessary true. Consider the case where one of the vectors is perpendicular to the normal, it could theoretically belong to both hemisphere; to eliminate the ambiguity, the test is exclusive and returns false in this case.
