Abstract

The invention discloses a dynamic texture modeling method and system, and the method comprises the following steps: obtaining a first texture change value when an object is static and a second texturechange value when the object is in key motion; and processing the first texture change value and the second texture change value by using a motion similarity measurement method to obtain a dynamic texture under any motion. According to the method provided by the embodiment of the invention, the texture of the object changing along with the movement is expressed through the group of linear bases,so that the three-dimensional model has a better expression effect.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a dynamic texture modeling method and system. Background technique [0002] The representation and reconstruction of 3D objects has a wide range of applications in many fields such as games, animation, and movies. The 3D model of an object should contain the geometry and texture information of the object, that is, model the geometry and texture. In many cases, the texture of an object is not static, but changes with the movement of the object. For example, dark wrinkles appear on the human face when making various expressions, but it is difficult to reproduce small geometric changes such as wrinkles in geometry, so it is more difficult to express using static texture and lighting models. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, an object ...
