The embodiment of the invention discloses a three-dimensional modeling method, a three-dimensional modeling device, three-dimensional modeling equipment, and a computer readable storage medium. The method comprises the steps of generating a two-dimensional contour line of an object to be modeled according to the operation that a user clicks a coordinate point in a three-dimensional coordinate system, wherein a one-dimensional coordinate in each coordinate point is set to be 0; and then according to upwards and downwards displacement information of a contact of the user on a plane perpendicularto the two-dimensional contour line, adjusting the height of the two-dimensional contour line on the plane, so as to convert a two-dimensional pattern into a three-dimensional pattern, thus generating a three-dimensional model of the object to be modeled. According to the technical scheme provided by the invention, a three-dimensional model of the object to be modeled is drawn in a human-computerinteraction manner, the user can dynamically add, modify and delete the three-dimensional model via an interface interaction mode according to own needs, so that the timely and quick building of thethree-dimensional model is achieved, the operation is convenient and quick, the three-dimensional modeling efficiency is enhanced, and the large-scale virtual scene building requirement is met.
