Embodiment Construction

[0025] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] The technical terms mentioned in the present invention are explained as follows:

[0027] Knowledge Forest: It is a brand-new fragmented knowledge aggregation model. The fragmented knowledge aggregation process is regarded as a three-stage knowledge forest generation process of "knowledge subject facet tree generation-fragmented knowledge assembly-cognitive relationship mining", which can Aggregate multi-source, one-sided, and disordered fragmented knowledge such as Chinese and English texts, pictures, videos and other multimedia resources into a model that conforms to the characteristics of multidimensionality, relevance, and integration of human cognitive learning.

[0028] Knowledge topic facet tree: refers to a hierarchical structure tree describing the organizational structure of a certain knowledge topic. ...

Abstract

The invention discloses a Unity3D-based knowledge forest virtual reality system realization method. The method comprises the steps of obtaining data, wherein the data comprises multiple knowledge domain topics, a cognitive relation among the knowledge domain topics, facets corresponding to the knowledge domain topics and knowledge fragments corresponding to the facets; establishing a knowledge domain topic facet tree; generating coordinate data of each knowledge domain topic through a hierarchical layout algorithm; on the coordinate data, generating coordinate data of points on each side through a numerical differentiation method; establishing a knowledge forest virtual scene; and customizing interaction of a virtual display controller. According to the method, the limitations of a two-dimensional visualization technology in forest scale, layout and interaction are broken through; a strong real sense is brought for users; and the method can be mastered by the users more easily.

Description

technical field [0001] The invention belongs to the field of virtual reality, and in particular relates to a method for realizing a virtual reality system based on a Unity3D knowledge forest. Background technique [0002] The rapid development of science and technology has led to an increasingly serious phenomenon of knowledge explosion. Multi-source, one-sided and disordered knowledge fragments have exacerbated the problem of human cognitive overload and learning lost. Knowledge forest is a brand-new knowledge aggregation model, which can aggregate knowledge fragments into a form that conforms to the characteristics of human cognition, and alleviate the above problems. However, the knowledge forest has a huge amount of data and complex structure, and it is difficult for users to directly understand it. It is necessary to apply data visualization related technologies to realize its visual display. [0003] As a relatively fast-growing technology in data visualization techno...
