A three-dimensional modeling method based on a complex planar image

Abstract

The invention relates to a three-dimensional modeling method based on a complex planar image, which comprises the following steps of identifying the planar image after graying to obtain a vector diagram of an outer contour; discretizing and complementing the vector diagram of the outer contour to obtain a construction curve; obtaining a symmetric relationship of the complemented construction curvethrough a two-time comparison method, and adding an auxiliary curve and a symmetric plane; calculating the position of the construction curve in a three-dimensional space on the basis of the symmetric relationship; and performing three-dimensional modeling on the basis of the added auxiliary curve, and combining the models. The modeling steps are simple, the operation is easy and convenient, andthe modeling requirements of non-professionals can be better met.

Description

technical field [0001] The invention relates to computer three-dimensional modeling, in particular to a three-dimensional modeling method based on complex plane images. Background technique [0002] A 3D model is a very common way to express real objects or animated characters in a computer, and most objects in the real world can be represented by a 3D model. Using computer 3D modeling can theoretically create a 3D model of any shape. Compared with real objects, using a computer for 3D modeling can repeatedly modify and edit 3D models, while real object modeling will be limited by the relatively fixed shape of the model. Due to the difficulty of modification and other effects, the production of real objects has the disadvantages of consuming more materials and requiring a lot of manpower and material resources compared to computer 3D modeling. In the development of computer graphics, 3D modeling is also an important subject, and many related researches have been carried out...

AI Technical Summary

Problems solved by technology

[0003] (1) The modeling steps are cumbersome. It is undeniable that such modeling can create a more refined model, but a seemingly simple model may take a lot of time to create

[0004] (2) The operation is complicated, and users without a lot of experience are often stumped by the complex interface of this type of modeling software, and often spend a lot of time looking for an operation function

[0005] From the above shortcomings, it can be seen that it takes a long time to use this kind of 3D modeling software, and requires professional training, which is very unfriendly to people without relevant professional knowledge; in addition, 3D modeling based on WIMP The modeling method has high requirements on the equipment and needs a high-performance computer to run well, but the performance of ordinary mobile devices such as tablets and smart phones cannot run this kind of modeling software, and users will be limited by the equipment and location. Constraints make it impossible to convert design ideas into models at any time, resulting in design inspirations that cannot be saved anytime and anywhere, which is also unfriendly to designers
