Abstract

Provided are a line segment attraction method, apparatus, device, and storage medium, said method comprising: determining line point projection information of each three-dimensional element displayed on a drawing canvas (S101); in response to receiving a selection operation acting on any line segment element in the drawing canvas, obtaining line point information of the selected line segment (S102); in response to receiving a movement operation acting on the selected line segment, determining a movement vector corresponding to a line segment to be attracted (S103); according to the line point information, the movement vector, and the line point projection information of each three-dimensional element, determining a target three-dimensional element to be attracted on the selected line segment (S104); controlling the selected line segment to be attracted to the target three-dimensional element (S105); displaying the combined three-dimensional element formed after attraction (S106).

Description

technical field [0001] The invention relates to the technical field of interactive smart panels, in particular to a line segment adsorption method, device, equipment and storage medium. Background technique [0002] Interactive smart tablet is one of the more important applications in interactive smart devices, widely used in various application scenarios, greatly improving people's work and study efficiency. For example, in educational scenarios, teachers can draw various elements such as plane or three-dimensional geometric diagrams and structural diagrams on the interactive smart tablet, so that teachers can explain teaching content with illustrations. [0003] When teaching three-dimensional elements based on an interactive smart tablet, it is usually necessary to drag a certain linear element onto the three-dimensional element. For example, the teacher can use the ruler tool of the interactive smart tablet to draw a line segment on the canvas, and then drag the line se...
