Example Embodiment

[0048] According to an embodiment of the present invention, determining that a two-dimensional geometric figure obtained after dimensionality reduction processing of a three-dimensional model contains a closed geometric figure may include:

[0049] If all vertices of a closed geometric figure are contained in the two-dimensional geometric figure in the two-dimensional geometric figure obtained after the dimensionality reduction processing of a three-dimensional model, it is determined that the two-dimensional geometric figure contains a closed geometric figure .

[0050] For example, such as Figure 2A As shown, the four vertices of a closed geometric figure ABCD are all located in the first two-dimensional geometric figure E1, it is determined that the first two-dimensional geometric figure E1 contains the closed geometric figure ABCD; Figure 2B If the vertex K of the five vertices of another closed geometric figure HIJKL is not in the second two-dimensional geometric figure E2, ...

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.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a processing method, device, electronic equipment and storage medium for three-dimensional model data. Background technique [0002] With the rapid development of computer graphics and image technology, developers have ushered in a period of rapid development in the development and application of 3D technology in order to better present users with more complex graphics and image presentation forms that conform to people's cognition. [0003] In the process of realizing the present invention, the inventor discovered that the prior art has at least the following problems: with the wide application of three-dimensional technology, while providing people with more three-dimensional, more intuitive and expressive presentation forms, due to the computer Limited by many conditions such as software and equipment hardware, the problem of slow rendering of 3D models often occurs....
