Abstract

The invention provides a stereoscopic graph display method and apparatus, and an electronic device. A stereoscopic graph outline comprises a bottom surface outline and an outline generatrix. The method comprises the steps of displaying a stereoscopic graph on a graphic user interface; receiving a rotating operation instruction for the stereoscopic graph; transforming a display view angle of the stereoscopic graph according to the rotating operation instruction; along with change of the display view angle of the stereoscopic graph, determining a visible part and an invisible part of the bottom surface outline at the current view angle and the position of the outline generatrix in real time; and displaying the outline generatrix according to the position of the outline generatrix, and differentially displaying the invisible part of the bottom surface outline and other parts of the stereoscopic graph outline. By applying the method and the apparatus, the visibility of the bottom surface outline and the position of the outline generatrix of the stereoscopic graph are determined in real time, and in a three-dimensional rotating operation process, the display of the outline generatix of the stereoscopic graph and the differential display of the invisible part of the bottom surface outline and other parts are realized, so that the display of the stereoscopic graph is more intuitive and the user experience is relatively good.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for displaying stereoscopic graphics. Background technique [0002] At present, in teaching, drawing and other scenarios, the display of three-dimensional graphic outlines is often involved. In the display process, for any viewing angle, the outline of the three-dimensional figure that we can see is usually displayed with a solid line, and the outline that we cannot see that is blocked by the three-dimensional figure is usually displayed with a dotted line. [0003] In the prior art, the above-mentioned display effect is usually achieved in a pseudo-3D manner, that is, at a specific viewing angle, the outline of the graphics at the viewing angle is manually drawn in a 2D drawing manner. by figure 1 Take the cylinder shown as an example. When looking down at the upper bottom of the cylinder at a specific angle in the figure, the arc ABCDEF of the ...
