Abstract

The invention relates to a method using three-dimensional modeling to continuously and automatically convert graphs into two-dimensional cartoon characters. The method includes the steps of firstly, reading a three-dimensional model, and acquiring the normal vector, principal curvature, Gaussian curvature and principal curvature direction of the apex of the three-dimensional model; secondly, placing the three-dimensional model into a three-dimensional space, drawing the edge contour line, which can have three-axis rotation around rotary points and rotary shafts, of the three-dimensional model,and performing three-axis regulation; thirdly, acquiring characteristic lines related to viewing points, and projecting the three-dimensional model into a two-dimensional cartoon scene to obtain thetwo-dimensional cartoon characters.

Description

technical field [0001] The invention relates to a method for continuously and automatically transforming graphics into two-dimensional comic characters by three-dimensional modeling, and belongs to the technical field of comic production. Background technique [0002] As a form of popular culture and art painting, two-dimensional comics have the artistic characteristics of low threshold, low technical content, exaggerated artistic shapes, concise colors and beautiful lines. However, this art form is restricted in the creation and production of animation companies due to the many procedures, huge workload, large number of producers, and limitations in technology and creation mode in the traditional creation mode, especially in scene processing. It is time-consuming and labor-intensive to draw images from different angles and positions separately. Contents of the invention [0003] The present invention provides a method for continuously and automatically converting graphic...
