Abstract

The invention discloses an in-place direction algorithm, a terminal and a storage medium. The method comprises: obtaining a crown mesh plane and a center point of the denture mesh model in a denture mesh model; dividing the tooth crown mesh surface into multiple A first region; select any point in the first region as the first vertex of the first region, and use the direction from the first vertex to the center point of the denture mesh model as the first candidate in-position direction; according to the first vertex, the denture mesh The center point of the grid model and the crown grid surface are used to obtain the first undercut area of ​​the crown grid surface in the first candidate seating direction; the smallest first undercut area among the first undercut areas of the crown grid surface The first candidate seating direction corresponding to the area is set as the final positioning direction of the denture mesh model. The invention solves the problem of low accuracy of the in-position direction of the denture generated in the existing denture design software.

Description

Technical field [0001] The present invention relates to the field of computer-aided design, and more particularly to a in-place directional algorithm, a terminal, and a computer readable storage medium. Background technique [0002] The dentures generated in the existing denture design software are often equivalent to the direction of the teeth long axis or simply utilize the outer edge of the denture of the teeth and the center point of the bite line as the position direction, but this generation The direction of denture is often insufficient enough, not the optimal inlet direction, and the denture edge is inserted into the preparation to cause the denture and the preparatory body. Inventive content [0003] The primary object of the present invention is to propose a problem that the in-position direction algorithm, terminal, and computer readable storage medium is intended to solve the accuracy of the denture in the existing denture design software. [0004] In order to achiev...
