Garment deformation method based on human body Laplace deformation

Abstract

The invention discloses a garment deformation method based on human body Laplace deformation, which comprises the following steps of (1) inputting a human body grid model and a garment grid model intoa space, and respectively performing discretization processing to obtain a discrete human body vertex set and a discrete garment vertex set; (2) respectively clustering the discrete human body vertexset and the discrete garment vertex set to form a uniform discrete human body vertex set and a uniform discrete garment vertex set; (3) defining a set of all vertexes in the uniform discrete human body vertex set and the uniform discrete garment vertex set as a vertex set V, and constructing a Laplacian matrix; (4) controlling the vertexes of the discretized and clustered human body grid model, and driving the discretized and clustered clothes grid model to perform real-time smooth deformation; and (5) mapping the deformed human body grid model and the clothing grid model back to the space inthe step (1) to complete the garment grid deformation based on the human body Laplace deformation.

Description

technical field [0001] The invention relates to the technical field of three-dimensional mesh deformation, in particular to a clothing deformation method based on human body Laplace deformation. Background technique [0002] The existing virtual fitting applications mainly include virtual fitting websites, virtual fitting mirrors and mobile virtual fitting systems. Among them, the more common is the three-dimensional virtual fitting mirror. The "Fitting Magic Mirror" developed by AR DOOR Technology Company in Russia and the "Active Lab" fully interactive virtual fitting mirror invented by Digital Fashion Company in Japan are typical cases of the practical application of virtual fitting mirrors. [0003] The advantage of the virtual fitting website is that it is easy to operate, and the threshold for equipment requirements is low; the disadvantage is that it is impossible to achieve the effect that is completely consistent with the user's figure through simple parameter adju...
