Loading method, device and electronic device for expression resource

Abstract

The present invention provides a method, device, and electronic device for loading expression resources; wherein, the method includes: obtaining the expression resources of the virtual character in the target animation; the facial expression of the virtual character is composed of at least one expression mixed shape; according to the virtual The degree of influence of the expression blend shape in the character's facial expression on the image of the target animation, determine the expression blend shape that needs to be loaded from the expression resource; load the expression blend shape determined from the expression resource. In this method, according to the degree of influence of the expression blend shape on the target animation, the expression blend shape is selectively loaded, and only the expression blend shape that has a greater impact on the image quality of the target animation can be loaded, and there is no need to load the image that has a greater impact on the target animation. The small expression blend shape not only ensures the playback effect of the animation screen, but also reduces the consumption of memory resources and computing resources of the device, which is conducive to the real-time rendering of high-quality facial expressions.

Description

technical field [0001] The present invention relates to the technical field of resource processing, in particular to a method, device and electronic equipment for loading emoticon resources. Background technique [0002] In film and television animation or game animation, the rendering effect of the facial expression of the virtual character plays an important role in the portrayal of the virtual character. In the related art, the blend shape provided by FACS (Facial Action Coding System) is usually used, and the auxiliary blend shape extended based on the blend shape is used for linear combination to obtain the facial expression of the virtual character. Usually, it is necessary to combine many kinds of blend shapes to obtain a facial expression of a virtual character; when there are a large number of virtual characters in the animation screen, or when high-quality or high-complexity facial expressions need to be displayed, it may be necessary to simultaneously Loading hun...
