摘要： Skin-attached features are placed on a computer generated character by defining a set of placement points on at least a portion of a skin surface of the computer generated character. For each placement point, a radius is defined for the placement point. For each placement point, a density value is determined for the placement point. The density value is a sum of weighted overlaps with neighboring placement points within the radius of the placement point. The weighted overlaps are functions of the radius of the placement point. The number of placement points in the set of placement points is reduced based on the density values.

摘要： A system and process for digitally representing a plurality of surface-attached geometric objects on a model. The system and process comprises generating a plurality of particles and placing the plurality of particles on a surface of the model. A first plurality of curves are generated and placed at locations on the model. Characteristics are defined for the first plurality of curves. A second plurality of curves is interpolated from the first plurality of curves at locations of the particles. A plurality of surface-attached geometric objects is generated that replaces all of the particles and the second plurality of curves.

摘要： A computer generated character is decorated with skin-attached features in computer graphics by defining a skin surface of the computer generated character. The skin surface is defined using a set of one or more connected parametric surfaces. Feature locations for the features are placed on the defined skin surface. Guide locations for guides are placed on the defined skin surface. The skin surface is partitioned into a plurality of cells. Each cell has a set of vertices. The set of vertices for each cell is a set of the guide locations. Interpolation weights are determined for the feature locations using the guide locations and the plurality of cells.
