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

Returns the squared distance between a point and a line.

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

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

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

Returns the squared distance between two points.

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.
