epsilonEquals

public boolean epsilonEquals(Polygon3d poly,
                             double eps)

Returns true if this polygon is equal to another polygon within a prescribed tolerance eps. The two polyons are considered to be equal if their vertex lists are equal (within the specified tolerance) except for possibly being shifted with respect to each other.

Parameters:

poly - polygon to be compared with

eps - tolerance value

Returns:

true if the polygons are equal

epsilonEquals(maspack.geometry.Polygon3d, double)

equals

public boolean equals(Polygon3d poly)

Returns true if this polygon is equal to another polygon. The two polyons are considered to be equal if their vertex lists are equal except for possibly being shifted with respect to each other.

Parameters:

poly - polygon to be compared with

Returns:

true if the polygons are equal

Applies a affine transformation to the vertices of this polygon.

Parameters:

X - affine transformation

inverseTransform

public void inverseTransform(AffineTransform3dBase X)

Applies an inverse affine transformation to the vertices of this polygon.
