waypoint markers that are 4-point stars are non-compulsory/compulsory airspace fixes. non-compulsory are white and compulsory are shaded black. The one's that have circles around them are fly-over airspace fixes. You'll find these prior to a turn. Once you overfly the waypoint, you can initiate an intercept maneuver to the next flight segment.
