Demonstration system based on dynamic geometry technology

Abstract

The invention discloses a demonstration system based on a dynamic geometry technology. The demonstration system comprises a material library which stores materials and provides a call interface, a material loading module which is used for serializing the materials, storing, analyzing and reconstructing serialized results into interactive material contents, switching events, constructing graphs andacquiring operation states, a material editing module which is used for embedding a material loading module, and calling the material loading module and a material library, a loose-leaf library whichis used for storing loose-leaf files, sharing the loose-leaf files and remotely calling the loose-leaf files, a loose-leaf editing module which is embedded with a material editing module, and is usedfor manufacturing loose-leaf files and storing the loose-leaf files into a loose-leaf library, and a demonstration module which remotely calls the loose leaves and the materials to form a demonstration material file so as to realize event switching of the currently demonstrated material file. According to the demonstration system based on a dynamic geometry technology, the dynamic geometric materials are reused, and an environment for selecting, combining and editing the dynamic geometric elements is provided for a user, and a plurality of material combinations can be conveniently used duringdemonstration, and interactivity is achieved during demonstration.

Description

technical field [0001] The invention relates to the technical field of dynamic geometry application, in particular, it is a demonstration system based on dynamic geometry technology. Background technique [0002] Dynamically drag the free points in the geometric figure to vividly obtain the dynamic process of the geometric figure maintaining the constraint relationship, so as to better understand the geometric properties contained in the geometric figure. The system with such characteristics is called dynamic geometry. Dynamic geometry software is a kind of dynamic mathematical digital resources that use mathematical logic and graphic geometric constraints to construct and draw graphics, and form interactive dynamic mathematical digital resources that can be used for independent exploration and demonstration. [0003] The prior art is often used in dynamic geometric drawing software to integrate paging and presentation functions. Users can set multiple pages in the dynamic ...
