Abstract

The embodiment of the invention discloses a composite three-dimensional figure display state regulating and controlling method and device and computer equipment. The method comprises the steps that acomposite three-dimensional figure which is about to be regulated and controlled in a canvas is determined, and the composite operation position of the composite three-dimensional figure in the canvasis determined; based on the composite operation position, a regulating operation ball corresponding to the composite three-dimensional figure is formed in the canvas; a dragging event acting on the regulating operation ball is monitored, and according to the dragging event, the display state of the composite three-dimensional figure in the canvas is regulated and controlled. By means of the method, a teacher can dynamically regulate and control the composite three-dimensional figure so as to show display states of the composite three-dimensional figure at different visual angles to students,the students are helped to comprehensively observe and understand the composite three-dimensional figure, and the solid geometry teaching experience is further improved.

Description

technical field

[0001] The invention relates to the field of computer application technology, in particular to a control method, device and computer equipment for a combined three-dimensional graphic display state. Background technique

[0002] In the process of solid geometry teaching, it is often necessary to show students the spatial effects of the combination of multiple solid figures. The above-mentioned combined solid figure mainly refers to a three-dimensional figure formed by combining multiple geometric objects in three-dimensional space.

[0003] In the current traditional teaching demonstration, the combined three-dimensional graphics constructed are often statically displayed on the teaching screen. Generally, they can be shown to students through perspective drawing and three-view methods, but the combined three-dimensional graphics cannot be dynamically adjusted to show students. Showing the display status of the combined three-dimensional graphics under differ...
