Abstract

The embodiment of the invention discloses an information processing method and device for image rendering, and the method comprises the steps: determining a viewpoint group of a three-dimensional model diagram based on the coordinates of all vertexes in the three-dimensional model diagram; in response to a received request for rendering the three-dimensional model diagram, for each viewpoint in the viewpoint group, judging whether the normal direction of any vertex in the viewpoint range points to the viewpoint or not; and if the normal direction of the vertex does not point to the viewpoint, reversing the normal. By establishing the viewpoint group capable of covering all the points of the model and uniformly detecting and correcting a large number of normal lines in the model, batch detection and correction of the normal lines are realized, the rendering correctness is improved, and the problem of missing surfaces in rendering is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to an information processing method and device for image rendering. Background technique [0002] In the model modified by manual intervention, because of the different tools used, the problem of model normal reversal will occur. This problem will lead to the phenomenon of missing faces in the single-sided rendering. [0003] In related technologies, for complex models, it is impossible to accurately correct defects in complex areas of the model on a large scale. Contents of the invention [0004] The main purpose of the present disclosure is to provide an information processing method and device for image rendering. [0005] In order to achieve the above object, according to the first aspect of the present disclosure, an information processing method for image rendering is provided, including: determining the viewpoint group of the 3D model graph based on th...
