Garment design method based on three-dimensional sketch in any sight

The invention discloses a garment design method based on a three-dimensional sketch in any sight. The technical scheme is as follows: putting forward three-dimensional sketch interaction in any sight direction based on the human body distance field and octree structure storage technology, directly drawing the three-dimensional sketch lines of the garment on the surface of a three-dimensional mannequin, establishing three-dimensional style lines through de-noising, resampling and approximating and editing the style lines by utilizing the curve modeling technology to obtain a style drawing; obtaining a point in the garment piece area by utilizing an interpolation method according to the three-dimensional style drawing, generating three-dimensional garment piece meshes by utilizing a triangulation method and splicing the garment piece meshes to obtain the three-dimensional garment; and establishing a three-dimensional style template, generating fit style lines according to user input to obtain ...
