Method Detail

distance

public static float distance(LineParametric3D_F32 l0,
                             LineParametric3D_F32 l1)

Distance of the closest point between two lines. Parallel lines are correctly handled.

Parameters:

l0 - First line. Not modified.

l1 - Second line. Not modified.

Returns:

Distance between the closest point on both lines.

distance

public static float distance(LineParametric3D_F32 l,
                             Point3D_F32 p)

Distance from the point to the closest point on the line.

Parameters:

l - Line. Not modified.

p - Point. Not modified.

Returns:

distance.

distance

public static float distance(LineSegment3D_F32 l,
                             Point3D_F32 p)

Distance from the point to the closest point on the line segment.

Parameters:

l - Line. Not modified.

p - Point. Not modified.

Returns:

distance.

distance

public static float distance(PlaneGeneral3D_F32 plane,
                             Point3D_F32 point)

Distance between a plane and a point. A signed distance is returned, where a positive value is returned if the point is on the same side of the plane as the normal and the opposite if it's on the other.

Parameters:

plane - The plane

point - The point

Returns:

Signed distance

distance

public static float distance(Sphere3D_F32 sphere,
                             Point3D_F32 point)

Returns the signed distance a point is from the sphere's surface. If the point is outside of the sphere it's distance will be positive. If it is inside it will be negative.

distance = ||sphere.center - point|| - r

Parameters:

sphere - The sphere

point - The point

Returns:

Signed distance

distance

public static float distance(Cylinder3D_F32 cylinder,
                             Point3D_F32 point)

Returns the signed distance a point is from the cylinder's surface. If the point is outside of the cylinder it's distance will be positive. If it is inside it will be negative.

Parameters:

cylinder - The cylinder

point - The point

Returns:

Signed distance

distance

public static float distance(Triangle3D_F32 triangle,
                             Point3D_F32 point)

Signed distance from a 3D point to 3D triangle. The sign indicates which side of the triangle the point is on. See DistancePointTriangle3D_F32 for the details.

Parameters:

triangle - 3D triangle

point - Point for which the closest point on the triangle is found

Returns:

The closest point
