Abstract

Disclosed are a method and apparatus for presenting an expansion process of a solid figure, and a device and a storage medium. The method comprises: displaying a solid figure in a current interface; determining a target expansion state of the solid figure and a target plane corresponding to the target expansion state according to a trigger instruction for the solid figure; and controlling the rotation of a ridge line of the solid figure, and presenting, in real time, an expansion form of the solid figure during the rotation process of the ridge line, so that the solid figure is finally expanded to be in the target expansion state on the target plane.

Description

technical field [0001] The present invention relates to the field of computer application technology, and in particular to a method, device, device and storage medium for displaying a three-dimensional graphic unfolding process. Background technique [0002] In the teaching of three-dimensional graphics, it is often necessary to show students the unfolded shapes of three-dimensional graphics (such as cubes, cylinders, and cones, etc.). At present, in most electronic devices with teaching demonstration software, generally only the expanded graphics of the three-dimensional graphics can be directly presented to the learners. [0003] This way of directly displaying the unfolded graphics is not conducive to learners knowing the process of converting from three-dimensional graphics to expanded graphics. Learners cannot understand the corresponding relationship between expanded graphics and three-dimensional graphics, which affects the experience of the teaching demonstration fun...
