Building model presentation and interaction method based on virtual reality technology

Abstract

The invention discloses a building model presentation and interaction method based on a virtual reality technology, and the method comprises the steps: carrying out the processing of a building modelin an Skp format, exporting the building model in an fbx format which can be used in Unity software, and importing a generated file in the fbx format into the Unity software; in Unity software, building a displayed scene, and according to the complexity degree of building design, arranging and dividing all components in the building model into a plurality of sub-parts; writing a gesture action script file, designing more than three gesture actions for displaying a scene, and operating the building model, so as to observe the building model from multiple angles; and deploying a built scene in the HoloLens to realize virtual reality display of the building model. According to the invention, various conversions such as scaling, rotation, movement and the like can be randomly carried out on the model in an unlimited virtual space through operation; when model observation is carried out, various gesture actions can be carried out very skillfully, and the difficulty of gesture operation doesnot exist.

Description

technical field [0001] The invention relates to a building model human-computer interaction technology. In particular, it relates to a method for presenting and interacting with architectural models based on virtual reality technology. Background technique [0002] In the field of architectural design, there are currently three main ways to visualize the model: one is to create a real sand table model according to the actual scale. This method is the most used in real estate real estate display. The sand table model is manufactured in a 1:1 ratio based on the architectural model designed by the architect, and can observe the style and style of the building as a whole. For example, in the design, construction, and sales of actual buildings, the developer will always make the model determined by the designer for discussion or display. This method is the most primitive and direct, and is the basic method used in all architectural designs at present. [0003] There are three...

AI Technical Summary

Problems solved by technology

First of all, in the design stage, as long as a small change is made to the architectural model design, a new sand table needs to be recreated, which is very inconvenient and timely effect check

Second, the production of sand tables also requires a certain cost, and it is not recommended to carry out large-scale and repeated production

But the high cost of 3D printers is still a problem

Third, although the sand table model is made in equal proportions according to the design, it still contains very little information

Except for professionals engaged in design, it is difficult for ordinary users to master it in a short time

Second, this method must be carried out on a computer with design software installed, and the model cannot be displayed anytime and anywhere, and the scene is limited

It can effectively solve the cost problem of making sand table or video and the effect problem that cannot be displayed in all directions in the traditional display method
