Generation of a 3D model of tufted hair from a line illustration
Details
In 3DCG, a hair model is important to represent a human model. However, modeling of hair models requires advanced modeling skills and time. We present a method of 3D modeling for easy creation of tufted hair models from a line illustration. First, the user selects points that belong to closed regions of hair. Secondly, we decide the back-or-front relationship of tufted hair shapes based on the line crossing information, which is then used to add depth offsets between back and front tufted shapes. The depth offsets are integrated into the global depth map calculated based on a rounded head shape. Lastly, we obtain a 3D hair model with a smooth shape by applying the smoothing process to the depth map. The user can obtain a 3D tufted hair model without complicated user input.
