Abstract: Disclosed is a three-dimensional projection binding point rendering method, which comprises: obtaining a 3D coordinate of a binding point in a three-dimensional character model, and calculating a 2D coordinate of the binding point in a 2D picture which is projected in the same projection manner as the three-dimensional character model according to the 3D coordinate of the binding point; calculating a binding point coordinate for each frame of a 2D projection picture in a character animation series to obtain all binding point coordinates corresponding to the character animation series; judging all the binding point coordinates in the character animation series and modifying a binding point coordinate with position mutation; and outputting all the binding point coordinates in a textual manner to obtain a binding point information text corresponding to the character animation series. Also disclosed is a three-dimensional projection binding point rendering device.
