Detailed Description

A boundingbox encloses the object's surface. The whole surface is inside the box between boxmin and boxmax. Boundingboxes are in upper-level space and always axis-aligned.

Constructor & Destructor Documentation

BoundingBox::BoundingBox (  Vector3  edgemin, Vector3  edgemax )  [inline]

Generates a bounding box from two edge points. All components of edgemin have to be smaller than the corresponding components of edgemax.

Member Function Documentation

Vector3 BoundingBox::getBoxMax (   )  const [inline]

Returns: Maximum edge point of the box.

Vector3 BoundingBox::getBoxMin (   )  const [inline]

Returns: Minimum edge point of the box.

DBL BoundingBox::intersect (  const Ray &  r, DBL  tmax )  const

Intersect Box with Ray limited to maximum time. Parameters: r  the Ray tmax  Maximum intersection time. Returns: -1 if no intersection, INTERSECTION_TIME_EPSILON if Ray's origin is inside the box otherwise the time of first intersection.

DBL BoundingBox::intersect (  const Ray &  r  )  const

Intersect Box with Ray. Parameters: r  the Ray Returns: -1 if no intersection, INTERSECTION_TIME_EPSILON if Ray's origin is inside the box otherwise the time of first intersection.

bool BoundingBox::isInsideAt (  const Vector3 &  a  )  const

Test point for box insidness. Parameters: a  the point Returns: true if the point is inside the box else false

void BoundingBox::transformate (  const TransparentTransformatable &  t  )

Transformate the box the same way as the given Transformatable. Parameters: t  the Transformatable
