Description

<p>We propose an intuitive and quick hair modeling system that uses a 3D canvas of any shape, including a head enclosure, flat surface, and hand-drawn outlines of hair bunches. The existing method of generating a bundle of hair using a single line as an axis is intuitive. Still, it isn't easy to reflect the user's intention in detail because it only adjusts the shape and automatically determines the thickness of the line as an axis. This method proposes a system that allows users to specify detailed figures more freely and intuitively by modeling a hair bundle from two contour lines, as in hand-drawn illustrations. The 3D canvas used in this process can be flexibly specified by isosurfaces covering the head, arbitrary planes and 3D models, and a function for creating a canvas by sweeping and interpolating input lines. In addition, the entire hair is quickly generated by duplicating the created hair bundle. The resulting images created by this system and subject experiments demonstrate the usefulness of the UI for hair modeling with intuitive operations similar to drawing on paper.</p>
