Method and device for processing three-dimensional model data, electronic device and storage medium

Abstract

The invention discloses a method and device for processing three-dimensional model data, an electronic device and a storage medium, and relates to the technical field of computers, and contributes toincreasing the rendering speed of a three-dimensional model. The processing method includes: extracting the three-dimensional coordinate values of the contour key points of a plurality of three-dimensional models; performing dimensionality reduction on the three-dimensional coordinate values of the contour key points in the same dimensionality direction to obtain corresponding two-dimensional coordinate values, wherein the connecting lines of the points determined by the two-dimensional coordinate values obtained after the dimensionality reduction of each three-dimensional model define a closed two-dimensional geometric figure; when it is determined that the two-dimensional geometric figure obtained after the dimensionality reduction of a certain three-dimensional model contains a closed geometric figure, deleting the two-dimensional coordinate values corresponding to the key points of the contained closed geometric figure from the two-dimensional coordinate values of the two-dimensional geometric figure obtained after the dimensionality reduction of the three-dimensional model. The method and device can be used in three-dimensional image display.
