Embodiment Construction
[0051] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0052]As shown in the background art, due to the use of fake eyeball models in the prior art, the authenticity of eyeball rotation is reduced, which in turn leads to a decline in the effect and quality of the 3D face model.
[0053] In order to solve the above problems, the embodiment of this application proposes a method for realizing the eyeball rotation effect based on a 3D human face. By collecting the vertex information of the eye edges of a 3D human face, an eye model object and a corr...

The invention discloses a method and equipment for generating an eyeball rotation effect based on a three-dimensional face. The method comprises the steps that a new eye model object and a corresponding model file are generated according to vertex information of the edge of an eye area on the three-dimensional face; a to-be-copied UV map is generated according to an eyeball area in an original UVmap in the model file and a preset offset position; the UV map to be copied is copied to the model object by utilizing mapping resources, so that the model object comprises a set of built-in UV map and a set of offset UV map; and transition switching is carried out between the built-in UV map and the offset UV map to generate the eyeball rotation effect. By applying the method, the eyeball rotation effect is generated according to transition switching of the two UV chartlets, so that the authenticity of eyeball rotation is improved, the facial expression is more flexible and vivid, the qualityof a three-dimensional face is improved, and the user experience is improved.
Description
technical field [0001] The present application relates to the technical field of portrait processing, and more specifically, to a method and device for realizing an eye rolling effect based on a three-dimensional human face. Background technique [0002] At present, the application field of 3D face imaging is more and more extensive, and it has also been applied to film and television animation, medical graphics, face recognition, virtual social interaction, etc. During use, the 3D model can be changed, beautified, etc. This increases the fun of the experience. [0003] If the eye part of the 3D model uses the UV map of the real user's eye area, it is impossible to control and rotate the eyeball in the eye area, and it is impossible to synchronize the eyeball rotation of the model by capturing the user's eyeball rotation through the camera, because at this time The eyes are limited by a single picture, and it is impossible to collect the complete UV map of the pupil and whi...
