Method and device for enlarging navigation map based on three-dimensional scene interactive platform

Abstract

The invention discloses a three-dimensional scene interaction platform-based guide map amplification method and apparatus. The method comprises the steps of presetting a global guide map and local guide maps of rooms; loading a triggering condition; when a user places an interactive module for performing interactive operation, obtaining position information of the placed interactive module, and judging whether the triggering condition is met; if yes, calling out the local guide map of the room where the interactive module is located, amplifying the local guide map, performing full screen display on a three-dimensional scene interaction platform, and executing the next step; otherwise, continuing to stay on the global guide map; and returning to the global guide map or continuing to stay on the current local guide map. According to the method and the apparatus, sufficient operation space can be provided; the operation is simple and convenient; and the user experience is improved.

Description

technical field [0001] The invention relates to the field of three-dimensional scene human-computer interaction, in particular to a method and device for enlarging a guide map based on a three-dimensional scene interactive platform. Background technique [0002] In human-computer interaction in 3D scenes, multiple interaction blocks are generally used, such as main perspective block, sofa block, chair block, cabinet block, table block, etc. When the furniture that needs to be placed in a room is diverse, the size of the existing guide map is limited, and the rooms on the guide map cannot accommodate more than one interactive cube. According to the display scale of the guide map in the traditional technology, when multiple interactive blocks are operated in a room, they are crowded together, making it difficult or even impossible to place them. At this time, the guide map needs to be enlarged. In the traditional technology, by using a multi-touch touch screen, the user uses ...

AI Technical Summary

Problems solved by technology

If the display scale of the guide map in the traditional technology is used, when multiple interactive blocks are operated in a room, they are crowded together, making it difficult or even impossible to place them. At this time, the guide map needs to be enlarged.

In the traditional technology, by using the multi-touch touch screen, the user uses two fingers to pull apart or approach to realize the enlargement or reduction of the navigation map. The disadvantage is that the touch screen is required, and the user operation is complicated.
