Displacement Map Using Spectral Operators
نویسندگان
چکیده
Displacement map is a modeling technique that creates shape by mapping the height field of the complicated shape feature on the surface of the target shape, which is preferable in describing sophisticated feature details. This paper investigates the techniques for fast creation of the displacement map based on the rich research achievements of shape analysis and digital signal processing. The possibility that fuses multi-discipline knowledge with that of shape modeling is explored. A generalized shape synthesis operation in frequency domain is formulated, as well as shape controls to achievement specific mapping effects, such as spherical mapping, cylindrical mapping and normal field mapping. The proposed approach provides comprehensive yet flexible control in shape modeling. Some shape models are provided to demonstrate the effectiveness of the proposed approach.

Strategies in localization proofs for one-dimensional random Schrödinger operators
Recent results on localization, both exponential and dynamical, for various models of one-dimensional, continuum, random Schrödinger operators are reviewed. This includes Anderson models with indefinite single site potentials, the Bernoulli– Anderson model, the Poisson model, and the random displacement model. Among the tools which are used to analyse these models are generalized spectral avera...
متن کاملSpectral Operators for the Manipulation of Point Sampled Geometry
In recent years, research on simple geometric primitive-based modeling techniques has attracted more and more attention from researchers worldwide. Point sampled geometry with the simplest form of representation is capable to provide the most flexible shape descriptions. It becomes, therefore, the hot spot in the study of shape modeling. However, interactive modification of the point cloud is a...
متن کاملNonlinear Finite Element Analysis of Bending of Straight Beams Using hp-Spectral Approximations
Displacement finite element models of various beam theories have been developed using traditional finite element interpolations (i.e., Hermite cubic or equi-spaced Lagrange functions). Various finite element models of beams differ from each other in the choice of the interpolation functions used for the transverse deflection w, total rotation φ and/or shear strain γxz, or in the integral form u...

Let $$(Lv)(t)=sum^{n} _{i,j=1} (-1)^{j} d_{j} left( s^{2alpha}(t) b_{ij}(t) mu(t) d_{i}v(t)right),$$ be a non-selfadjoint differential operator on the Hilbert space $L_{2}(Omega)$ with Dirichlet-type boundary conditions. In continuing of papers [10-12], let the conditions made on the operator $ L$ be sufficiently more general than [11] and [12] as defined in Section $1$. In this paper, we estim...
