Member Function Documentation

static double csDSquaredDist::PointLine ( const csDVector3 p,
const csDVector3 l1,
const csDVector3 l2 
) [static]

Returns the squared distance between a point and a line.

static double csDSquaredDist::PointPlane ( const csDVector3 p,
const csDPlane plane 
) [inline, static]

Returns the squared distance between a point and a normalized plane.

Definition at line 581 of file math3d_d.h.

static double csDSquaredDist::PointPoint ( const csDVector3 p1,
const csDVector3 p2 
) [inline, static]

Returns the squared distance between two points.

Definition at line 573 of file math3d_d.h.

static double csDSquaredDist::PointPoly ( const csDVector3 p,
csDVector3 V,
int  n,
const csDPlane plane,
double  sqdist = -1 
) [static]

Returns the squared distance between a point and a polygon.

If sqdist is >= 0, then it is used as the pre-calculated point to plane distance. V is an array of vertices, n is the number of vertices, and plane is the polygon plane.
