Problems solved by technology

from figure 1 It can be seen that since there are no line elements, when displaying the ridges of 3D graphics, the same ridges will have different thicknesses and there will be gaps at the ridge interface
At the same time, due to lighting, the brightness of the same ridge line will be inconsistent
Therefore, the existing display scheme cannot accurately display three-dimensional graphics

Abstract

The invention discloses a three-dimensional graph display method and apparatus, a device and a storage medium. The display method comprises the steps of obtaining display data of a set display layer of a to-be-displayed three-dimensional graph in a display screen, wherein the set display layer comprises a real line layer and an imaginary line layer, and the real line layer covers the imaginary line layer; and according to the display data, displaying edge lines facing a user in the real line layer, and displaying edge lines deviating from the user in the imaginary line layer, thereby displaying the three-dimensional graph in the display screen. By adopting the method, an existing three-dimensional graph display scheme can be optimized to achieve the technical effect of accurately displaying the edge lines of the three-dimensional graph in the display screen.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional imaging, in particular to a display method, device, equipment and storage medium of three-dimensional graphics. Background technique [0002] With the rapid development of computer software and hardware, the application of computer graphics in various industries has also been rapidly popularized and deepened. At present, computer graphics has entered the three-dimensional era, and three-dimensional graphics are ubiquitous around people. For example, in the cognitive teaching of solid geometry based on multimedia, it is usually necessary to show students the shapes of vertices, ridges and surfaces of three-dimensional graphics. [0003] In the prior art, when using a 3D engine to draw 3D graphics, since there is no "line" element in the 3D engine, it is necessary to use cylinders or surfaces to simulate lines during the drawing process. in, figure 1 For 3D graphics drawn using ...
