Member Function Documentation

◆ GetClosestCorner()

template<class TYPE >
C3DTPoint< TYPE > C3DTBBox< TYPE >::GetClosestCorner ( const C3DTPoint< TYPE > &  pt) const
inline

<

Returns the closes point of the bbox to the given point

◆ GetGreaterUniformBBox()

template<class TYPE >
C3DTBBox< TYPE > C3DTBBox< TYPE >::GetGreaterUniformBBox ( ) const
inline

<

Returns a bbox with same sizes on X,Y,Z axys. This bbox contains the referenced bbox

◆ GetRadius()

template<class TYPE >
double C3DTBBox< TYPE >::GetRadius ( ) const
inline

<

Returns the radius of the sphere that contains the whole bbox

◆ IsInBox()

template<class TYPE >
bool C3DTBBox< TYPE >::IsInBox ( const C3DTPoint< TYPE > &  pt,
bool  strictlyInside = false 
) const
inline

<

Returns false if box is invalid or NULL, as it is considered as void box. If strictlyInside, the point cannot be on the box plane

◆ IsInitialized()

template<class TYPE >
bool C3DTBBox< TYPE >::IsInitialized ( ) const
inline

<

Useful to know if the bounding box has been computed

◆ IsValid()

template<class TYPE >
bool C3DTBBox< TYPE >::IsValid ( ) const
inline

Invalid bounding box, means that min is greater than max.

If init = false, this only means that bounding box is empty, but it is valid. If min == max, then it is valid but null

◆ RayIntersect()

template<class TYPE >
bool C3DTBBox< TYPE >::RayIntersect ( const C3DTPoint< TYPE > &  orig,
const C3DTVector< TYPE > &  dir,
double &  t 
)
inline

Return true only if ray intersect the bbox which is in front (otherwise dist < 0).

We can know the contact point using point = orig+dir*t Note: RayIntersect might be called with the negation of a vector. In that case, 0.0 value is supposed to be always position 0 (+0.0), otherwise we can miss an intersection and t will be negative and it should be positive
