Abstract

The invention relates to the field of computer mapping, and provides a dynamic geometry software achieving method based on variables and mathematical expressions. The problems that few dynamic geometry software construction methods exist in the prior art and application limitations are large is solved. The method mainly comprises the steps of building a dynamically-added variable library, constructing a constraint relationship, designating the influence relation between related variables and geometrical elements or sliding rods, and adjusting actual variable values. According to the technical scheme, a certain variable of the geometrical elements can be precisely controlled instead of using a free point as a basic unit, and therefore the application range is enlarged.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a realization method of dynamic geometry software based on variables and mathematical expressions. Background technique [0002] At present, the popular dynamic geometry software on the market is based on a directed acyclic graph to store geometric objects and their relationships. When the user actively changes a geometric object, the system will first determine the position of the geometric object in the directed acyclic graph. If the current geometric object has no parent node, it will directly move the object and traverse the descendant elements in the graph, according to The corresponding geometric relationship moves to complete the dynamic change of geometric elements; if the current geometric object has a parent node, search upward until an element without a parent node is found to move, and traverse the descendant elements in the graph, and then move according to the corre...
