Member Function Documentation

void LSS::ComputeOBB

(

OBB &

box)

Computes an OBB surrounding the LSS.

Parameters

box	[out] the OBB

inline_ bool LSS::Contains ( const Point &  pt) const

inline

Tests if a point is contained within the LSS.

Parameters

pt	[in] the point to test

Returns

true if inside the LSS

Warning

point and LSS must be in same space

Definition at line 41 of file IceLSS.h.

{ return SquareDistance(pt) <= mRadius*mRadius; }

inline_ bool LSS::Contains ( const Sphere &  sphere)

inline

Tests if a sphere is contained within the LSS.

Parameters

sphere

[in] the sphere to test

Returns

true if inside the LSS

Warning

sphere and LSS must be in same space

Definition at line 51 of file IceLSS.h.

                        {
                            float d = mRadius - sphere.mRadius;
                            if(d>=0.0f) return SquareDistance(sphere.mCenter) <= d*d;
                            else        return false;
                        }

inline_ bool LSS::Contains ( const LSS &  lss)

inline

Tests if an LSS is contained within the LSS.

Parameters

lss	[in] the LSS to test

Returns

true if inside the LSS

Warning

both LSS must be in same space

Definition at line 66 of file IceLSS.h.

                        {
                            // We check the LSS contains the two spheres at the start and end of the sweep
                            return Contains(Sphere(lss.mP0, lss.mRadius)) && Contains(Sphere(lss.mP0, lss.mRadius));
                        }
