The invention discloses an achievement method for virtualizing three-dimensional glass breaking animations. The achievement method comprises the following steps of S1, utilizing an image of an entity with cracks to obtain a glass breaking data model; S2, virtualizing a striking object mode; S3, breaking the established glass breaking data model; S4, virtualizing the breaking animations. The achievement method for virtualizing the three-dimensional glass breaking animations comprehensively utilizes a three-dimensional software breaking program, an extrusion program and the like and can achieve production of the vivid and accurate breaking animations, the process is simple and clear, and the technical problems of inaccuracy, poor effect and complicated operation in the prior art are well overcome. Compared with the prior art, the achievement method is good in effect and simple and convenient to operate.
