Rapid hair modeling method based on surface grids

Abstract

The invention discloses a rapid hair modeling method based on surface grids. In the invention, through simple surface shape grid control on the target hair style, the hair modeling process is simplified, and the same high-quality modeling result is obtained. According to the invention, the hair modeling result completely conforming to the shape grid can be produced simply by creating a rough surface grid approximately representing the hair shape with a common grid modeling method by a user, and then obtaining sparse hair track lines corresponding to the shape grid through a full-automatic track line extraction method and based on the track lines and a hair attachment grid designated by the user. Based on the modeling result, the stylization effect can be further obtained through a stylization method easily controlled by user while keeping the modeling shape. The hair modeling mentioned in the specification refers to a process of modeling the target hair objects into a set of abundant superfine hairline geometries.

Description

technical field [0001] The invention relates to the field of computer animation character modeling and physical simulation, in particular to a hair object modeling and simulation method. Background technique [0002] Hair is an important feature that reflects the character's personality. The modeling of hair objects for various virtual characters in computer animation and games is a key step in character modeling. An accurate, efficient, convenient and easy-to-use interactive hair modeling method is very important for Character modeling is critical. However, due to the extremely complex geometric structure and ever-changing style effects of hair, it is difficult for users to skip the cumbersome and abstract interactive means to intuitively control the final hair shape. For example, modeling software such as Maya and Blender are currently widely used, although combing tools can And methods such as guiding hair strands to control the appearance of hair, but it is still imposs...

Problems solved by technology

Although these methods can simulate the hair structure globally in a more convenient way, the results are usually simple and blunt, and the final shape of the hair cannot be directly controlled

[0005] Since the existing hair modeling methods either require a lot of tedious user interaction to achieve the desired hair shape, or can only automatically obtain simple and unpredictable modeling results, and these methods are only for the special case of hair modeling, Difficult to reuse other modeling techniques, so often difficult to master and apply
