double PointPoint (const csDVector3 &p1, const csDVector3 &p2)

Returns the squared distance between two points.

double PointLine (const csDVector3 &p, const csDVector3 &l1, const csDVector3 &l2)

Returns the squared distance between a point and a line.

double PointPlane (const csDVector3 &p, const csDPlane &plane)

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

Detailed Description

Some functions to perform squared distance calculations.

This is a static class and contains only static member functions.

Member Function Documentation

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.
