Method Details

isInsideOut

public static boolean isInsideOut(Vec3Arg scale)

Test whether the specified scale turns 3-D normals inside-out.

Parameters:

scale - the scale vector to test (not null, unaffected)

Returns:

true if it turns normals inside-out, otherwise false

isNotScaled

public static boolean isNotScaled(Vec3Arg scale)

Test whether the specified scale is close to identity.

Parameters:

scale - the scale vector to test (not null, unaffected)

Returns:

true if identity, otherwise false
