Abstract

The invention discloses an unfolding and displaying method and apparatus of solid figures, an electronic device and a storage medium. The unfolding and displaying method of solid figures includes the steps: determining a solid figure to be unfolded, and acquiring the to-be-unfolded state of the solid figure; looking for the hinged relation group corresponding to the to-be-unfolded state in a preset multi-level information relation table; according to the hinged relation group and a preset unfolding rule base, determining the target unfolding rule of each target surface plane on the solid figure; and controlling the target surface plane to be unfolded in the set rate, based on the corresponding target unfolding rule, and displaying the unfolding process in real time. The unfolding and displaying method of solid figures can dynamically display an unfolding process of the solid figure for a learner so as to enable the learner to deeply understand the forming process from the solid figure to the selected unfolded state so as to preferably improve the user experience of the teaching demonstration function of the electronic device.

Description

technical field [0001] The present invention relates to the field of computer application technology, in particular to a method, device, electronic equipment and storage medium for unfolding and presenting three-dimensional graphics. 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] The direct presentation of the three-dimensional graphics to the expanded graphics is not conducive to learners' deep understanding of the formation process of the expanded graphics, thus affecting the experience of the teaching demonstration function. Contents of the invention [0004] Embodiments of the present invention provide a method...
