Benefits of technology

The present invention allows for easy creation of meshes with varying shapes using feathers models made from curved line segments. This makes it easier to create complex meshes without requiring complicated calculations or simulations.

Problems solved by technology

This patent describes how to use 3D scanners to generate highly accurate representations of complex shapes such as those found in virtual reality. However, existing methods cannot fully represent changes caused by external forceings like bending or stretching.

Embodiment Construction

[0040]Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

[0041]FIG. 1 is a diagram showing a geometrical curve model of a feather to which the present invention is applied.

[0042]As shown in FIG. 1, a geometrical curve model of a feather has a form where plurality of barbs are attached to a shaft.

[0043]In this case, the barbs are configured of a plurality of groups of barbs g1, g2, g3, g4, and g5 as shown in FIG. 1. The barbs included in each group of barbs faces a predetermined direction and each of the groups of barbs face different directions. In other words, since the barbs move in a unit of the groups of barbs, when the motion of barbs is represented by a computer, it is efficient to use the polygonal mesh models similar to the shape of the aggregation of the curved lines rather than representing the curve model of barbs.

[0044]Therefore, when the apparatus for generating the mesh models of the feathers according

Abstract

Provided are an apparatus and a method for generating mesh models of feathers. The apparatus for generating the mesh models of the feathers includes a geometrical model analyzing unit that analyzes groups of barbs included in a geometrical curve model of the feather; a calculating unit that calculates the number of grids for each of the groups of barbs by applying curve lengths of the barbs and an average length of the curve lengths included in each of the groups of barbs; and a mesh model generating unit that constructs the geometrical curve models as polygonal mesh models based on the number of grids. According to the present invention, it extracts curved points by using characteristics of a model of a feather and constructs polygonal meshes by using the extracted curved points, thereby making it possible to physically and realistically express the forced physical variation of the polygonal meshes.
