Member Function Documentation

static float csSquaredDist::PointLine ( const csVector3 p,
const csVector3 l1,
const csVector3 l2 
) [static]

Returns the squared distance between a point and a line.

static float csSquaredDist::PointPlane ( const csVector3 p,
const csPlane3 plane 
) [inline, static]

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

Definition at line 243 of file math3d.h.

static float csSquaredDist::PointPoint ( const csVector3 p1,
const csVector3 p2 
) [inline, static]

Returns the squared distance between two points.

Definition at line 232 of file math3d.h.

static float csSquaredDist::PointPoly ( const csVector3 p,
csVector3 V,
int  n,
const csPlane3 plane,
float  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.
