Point Entity is usually defined as simply an entity that is not a brush entity i.e. entity that is created by Hammer Entity Tool on specific point on a grid instead of tying brushes to an entity. More meaningful definition for a point entity is an entity that doesn't render a 3D model and its position in the world affects its functionality. It still may have a visual component (env_sprite, keyframe_rope) or create a visual component (infodecal, info_particle_system) but most of them are without one (ambient_generic, info_target, point_hurt, info_teleport_destination, info_elevator_floor). Other types of entities that are also created on a specific point and are usually referred to as point entity are model entities and logical entities. Point entities by these standards are most of the time subclasses of CPointEntity.
