Embodiment Construction

[0033] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0034] An interactive 3D relief method and implementation method suitable for 3D printing, which can be divided into importing model files and image files, selecting regions of interest, mapping from 2D images to 3D models, exporting mesh models and performing 3D printing. The main steps:

[0035] (1) Select the area of ​​interest

[0036] (1.1) Construct the cutting surface

[0037] Taking M model and P image as an example, based on OpenGL, Assimp and OpenCV import M model file and P image respectively. The order of vertex selection is clockwise as an example. The first step is to select two vertices v in turn on the M model through mouse input a , v b . The cutting plane is:

[0038]

[0039] where v a =(x 1 ,y 1 ,z 1 ), v b =(x 2 ,y 2 ,z 2 ).

[0040] (1.2) Construct cutting path

Abstract

The invention belongs to the technical field of computer aided design and industrial design and manufacturing, and provides an interactive 3D embossment method suitable for 3D printing. The method comprises the steps: loading a 3D model file and a two-dimensional image file; mapping the two-dimensional image to a region of interest specified by a model user to form a 3D embossment; and finally, printing the embossment model through a 3D printer. The method for obtaining the 3D embossment model is suitable for non-professionals to design the 3D embossment suitable for 3D printing. The method has the characteristics of simplicity, high interactivity and the like. Compared with a traditional embossment generation method, the method has the advantages of being high in interactivity, easy and convenient to operate and the like.

Description

technical field [0001] The invention belongs to the technical fields of computer-aided design and industrial design and manufacture, and relates to an interactive 3D relief method, which is suitable for the design and manufacture of general model 3D reliefs. Background technique [0002] Relief technology can theoretically be designed using relief design software such as Jingdiao and ArtCAM, but such relief software is complex to operate and requires trained professionals to operate proficiently, so it cannot be widely used, and it is difficult for non-professionals to use it proficiently. The interactive 3D relief method of the present invention has many advantages such as simplicity and strong interactivity, and is suitable for non-professionals to design 3D reliefs that can be used for 3D printing. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a simple and easy-to-operate interactive 3D relief system implementati...
