plane definition class

Constructor & Destructor Documentation

CPlane::CPlane (    )  [inline]
 

constructor

CPlane::CPlane (  zfloat    a,
zfloat    b,
zfloat    c,
zfloat    d
)  [inline]
 

constructor

CPlane::CPlane (  const CVector3 &    v1,
const CVector3 &    v2,
const CVector3 &    v3
)  [inline]
 

constructor

CPlane::CPlane (  const CVector3 &    v,
const CVector3 &    n
)  [inline]
 

constructor

v is plane origin and n is the normal

CPlane::CPlane (  const CPlane &    p,
zfloat    dist
)  [inline]
 

constructor

dist is the distance respect plane p

Member Function Documentation

zfloat CPlane::Dist (  const CVector3 &    v )  const [inline]
 

returns the distance between a point and the plane

bool CPlane::IntersectPlanes (  const CPlane &    P2,
const CPlane &    P3,
CVector3 &    inter
)  const [inline]
 

returns the intersection between the plane and other two planes

returns false if there is no solution.

zuint CPlane::MaxNormCoord (    )  const [inline]
 

returns which is the maxiest coord of the normal to the plane

CVector3 CPlane::Norm (    )  const [inline]
 

Returns the plane normal.

CVector3 CPlane::NormUnit (    )  const [inline]
 

returns the normalized plane normal

zuint CPlane::RayIntersection (  const CVector3 &    v1,
const CVector3 &    v2,
CVector3 &    result
)  const [inline]
 

return the intersection between the plane and the segment (v1,v2)

returns the following values:

  • INT_COINCIDENT (0) if the segment (v1,v2) lays on the plane.
    in this case result assumes the value of v1.
  • INT_ALLIN (1) if the segment (v1,v2) is inside the plane.
  • INT_ALLOUT (2) if the segment (v1,v2) is outside the plane.
  • INT_OK (3) if the segment (v1,v2) crosses the plane.
    In this case the intersection vertex is stored in result
