Member Function Documentation

zuint CPolygon::ClipToPlane (  const CPlane &    p )

polygon clipping

CVector3 CPolygon::ClosestPointOnPoly (  const CVector3 &    p )  const

returns the the nearest point to the polygon perimeter

zfloat CPolygon::Dist (  const CVector3 &    v )  const

returns the minimum distance between one vertex and the vector

CPlane CPolygon::GetPlane (    )  const

returns the plane in which lays the polygon

bool CPolygon::IsInside (  const CVector3 &    v )  const

test if the vector v is inside the polygon This code applies only to convex polygons. Dim: Given a line segment between P0 (x0,y0) and P1 (x1,y1), another point P (x,y) has the following relationship to the line segment. Compute (y - y0) (x1 - x0) - (x - x0) (y1 - y0) if it is less than 0 then P is to the right of the line segment, if greater than 0 it is to the left, if equal to 0 then it lies on the line segment.

zuint CPolygon::MaxNormCoord (    )  const

returns what is the biggest coord of the polygons normal

zfloat CPolygon::MaxX (    )  const
