Embodiment Construction

[0031] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as figure 1 as shown, figure 1 The texture-based three-dimensional mesh model deformation method in the embodiment of the present invention is shown, and the method mainly includes the following steps:

[0033] S101: Extract grid vertex positions from an existing grid model;

[0034] S102: Construct a deformation texture according to the grid vertex position and the skeleton model corresponding to the network model and its local frame information;

[0035] S103: Apply the deformed texture to the specified model to generate a deformed effect.

[0036] Specifically, the deformation texture in the method of the present invention is a feature description method applied to deformation. When computing the deformed texture, two important definitions are used: the initial pose and the constrained pose. The initial pose is generally a pose in w...

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a texture-based three-dimensional grid model deformation method and system. Background technique [0002] Nowadays, mesh model deformation is still an important means of 3D model modeling, and deformation transfer, which can transfer the deformation carefully constructed by an artist on one mesh model to another model, is also one of the hot spots in recent years. [0003] Mesh model deformation is an important means of 3D model modeling, one of which is the use of skin technology. This technology obtains the approximate pose of the model through skeleton adjustment in advance, and then realizes the deformation of the entire model by skinning the skeleton. In recent years, many researchers have done a lot of research on graphics skinning, graphics deformation, deformation transfer, etc., and have obtained a lot of results. However, due to the complexi...
