Scene description file generation method and device

The embodiment of the invention provides a scene description file generation method and device, and relates to the technical field of video processing. Comprising the steps of determining a tactile media accessor associated with a target action node when a to-be-rendered three-dimensional scene executes a target tactile action; the tactile media accessor is an accessor used for accessing tactile rendering data of a tactile media file declared in the MPEG media description module associated with the target action node when executing the target tactile action; generating a target tactile object description module according to the tactile media accessor, and adding the target tactile object description module into the MPEG tactile description module; and generating a target tactile action node array according to the index value of the node description module corresponding to the target action node and the index value of the target tactile object description module, and adding the target tactile action node array
