Field of the Invention The present invention relates to a laser processing apparatus, a laser processing method, and a program product. 2. Description of the Related Art A stereolithography apparatus is used to manufacture a three-dimensional object by irradiating a liquid resin, which is resin dissolved in a light-transmitting liquid, on a powder material (hereinafter referred to as a powder resin) contained in a lower vessel. The liquid resin is irradiated on the powder resin by using a laser beam generated by a laser oscillator that is a light source. The resin is polymerized, cured and hardened by the irradiation of the laser beam. After the polymerization, the powder resin is moved upward in the lower vessel by the force of its own weight. Thereafter, the powder resin is discharged from an opening portion of the lower vessel. Then, the powder resin discharged from the opening portion is cured in a heating furnace. The cured powder resin is again moved upward in the lower vessel and removed from the opening portion of the lower vessel. The above process is repeated to manufacture a desired object. When the resin is polymerized, cured and hardened by the irradiation of the laser beam, the powder resin is heated to high temperature and a large amount of heat energy is generated. It is necessary to quickly cool the powder resin to prevent deformation and distortion of the object. Therefore, a heat exchanger for rapidly cooling the powder resin is provided to the lower vessel. The powder resin heated by the laser beam is cooled by using the heat exchanger. The light irradiation of the laser beam is performed by moving a mask having a predetermined shape in a direction orthogonal to the longitudinal direction of a scanning region, in which the laser beam is scanned, or in the direction parallel to the longitudinal direction of the scanning region, for each layer. The direction of the scanning region is the direction in which the powder resin is moved in the lower vessel. In the conventional laser processing apparatus, the scan region, in which the laser beam is scanned, is fixed to the lower vessel. Therefore, a powder resin discharged from the upper opening portion of the lower vessel is scanned by the laser beam along a straight line, which is parallel to the direction of the scan region, and is moved in the direction orthogonal to the direction of the scan region, thereby forming the
