The input data is a surface originally represented by a dense polygonal mesh. The hierarchical adaptive structure is constructed by an iterative a simplification process that concomitantly generates a hierarchical parametrization of the mesh. The coarsest level of the representation defines the base domain which stores the original geometry via a local parameterization process. We apply local modifications to this base domain according to predefined functions (i.e. Perlin noise, Gabor Noise or a specific localized deformation) and propagate it to the original mesh. The decimation process and the local parameterization are done simultaneously using stellar operations. Our main contribution is a method that explores the power of adaptive hierarchical structures to generate detail with a greater degree of control. Also, the proposed method preserves the characteristics of the original mesh with more intensity through a process of decimation sensitive to features. The same detected features are used along with information of the discrete geometry to guide the generation and mapping of the noise. \^defgܺzeN9'9#h>%B*CJOJQJ^JaJph""")h"]Gh"]GB*CJOJQJ^JaJph""",h>%h"]G5B*CJOJQJ^JaJph""")h>%h"]GB*CJOJQJ^JaJph""":h>%h"]GB*CJOJQJ^JaJfHph"""q Bh>%h>%B*CJOJQJ^JaJfHmHph"""q sHBh>%h"]GB*CJOJQJ^JaJfHmHph"""q sHEh>%h"]G5B*CJOJQJ^JaJfHmHph"""q sH ^f $d7$8$H$a$gd>%gd>%$a$gd>% g6 > v w !
