const

Returns: true if at lease one coordinate is not zero and no coordinates are unset or nans.

IsUnset()

bool ON_3dPoint::IsUnset

(

)

const

Returns: True if any coordinate is ON_UNSET_VALUE or ON_UNSET_POSITIVE_VALUE

IsUnsetOrNan()

bool ON_3dPoint::IsUnsetOrNan

(

)

const

Returns: False if any coordinate is infinite, a nan, or ON_UNSET_VALUE.

IsZero()

bool ON_3dPoint::IsZero
