The application discloses an immersion interactive method and device for appreciating artifacts, and relates to the technical field of human-computer interaction. The method comprises the following steps: in an immersive digital experience cabin, the three-dimensional coordinates of the user's double pupils and the hand skeleton node coordinates are collected, the gesture instruction is analyzed, and the three-dimensional space viewpoint parameter set of the next moment is predicted; in a virtual engine scene, the UV texture coordinates are obtained by ray intersection, the three-dimensional region of interest is demarcated, the candidate tile set and the tile topology feature matrix are retrieved and generated; based on the pre-constructed fitness function, the improved tornado optimization algorithm is used for solving, and the global optimal tile loading sequence is output; the naked-eye light field rendering and the three-dimensional space multi-modal superposition are performed on the global optimal tile loading sequence, and the fusion picture of the artifacts and the suspended interpretation is presented on the naked-eye 3D cabin screen. The application solves the problems of viewpoint prediction lag, texture tile loading leading to video memory overflow or picture damage, and lack of spatial multi-modal fusion in the prior art.

Systems and methods for fast light field rendering from a three-dimensional (3D) representation of a scene. In at least one embodiment, fast light field rendering exploits cached color values of a plurality of color planes corresponding to a reference view and cached transmittance values of a plurality of transmittance planes corresponding to the reference view to composite a light field quilt via a single sweep through a plurality of sampling planes / volume chunks, thereby enhancing computational efficiency during rendering.
