1. A displaying method for a three-dimensional object, comprising steps of:
acquiring a plurality of pieces of original position information of a plurality of associated three-dimensional points in a target object model, acquiring human eye position information of human eye, and acquiring display position information of a preset picture display region in a picture display device;
determining a plurality of pieces of projection position information of the plurality of associated three-dimensional points on the preset picture display region according to the plurality of pieces of the original position information, the human eye position information, and the display position information, wherein the projection position information is projection position information points of the plurality of associated three-dimensional points that are viewed according to the human eye position information and projected onto the preset picture display region when transferred in a sight line light path; and
generating and rendering a projection picture of the target object model in the preset picture display region according to the plurality of pieces of projection position information,
wherein determining the plurality of pieces of projection position information of the plurality of associated three-dimensional points on the preset picture display region according to the plurality of pieces of original position information, the human eye position information, and the display position information comprises:
constructing connecting straight lines of the human eye position information and each piece of original position information; and
determining intersection points of the connecting straight lines of the plurality of pieces of original position information and the display position information as the plurality of pieces of projection position information.
