Method and system for realizing ten-million-level instance retrieval interaction based on real-time 3D (three-dimensional) engine

The invention discloses a ten-million-level instance retrieval interaction implementation method and system based on an instant 3D engine, and the method comprises the steps: making a plurality of independent instances in DCC (Digital Content Creation) software, and independently storing instance data; combining a plurality of instances into a set instance, importing the set instance into a 3D engine, and creating a three-dimensional data tree; a certain local part of the set instance is selected, the UV coordinates of the local part are read, the local UV axis number is obtained, namely the XY value of the local UV axis number in the three-dimensional data tree, and instance data contained in the Z value of the local part in the three-dimensional data tree are read according to the XY value of the local part. The method can be applied to data retrieval and positioning of huge instances, data positions are directly and accurately positioned in a three-dimensional data tree, and data are efficiently read; in t
