Manipulating mesh gradient field is an important component of a poisson mesh editing system it is noted that it would be tedious to interactively define a local transform for every triangle of a mesh. The purpose of applying the poisson equation is to solve an un- 32 gradient field editing using local transforms known target mesh with known topology but unknown geometry (vertex coordinates.

Poisson image editing parallel method on mesh poisson based mesh editing mesh editing with poisson-based gradient field manipulation.
When two shapes to be morphed are different in shape and topology, a new method which combines shape deformation theory based on laplacian coordinate and mean value coordinate with distance field theory is proposed for the efficient treatment of vertex correspondence and path interpolation problems. This list is by no mean representative of all fields of computer graphics, i may have forgotten very important papers, included irrelevant ones or misclassed a few articles in each category, papers are in no particular order.

This paper presents a novel 2d shape deformation algorithm based on nonlinear least squares optimization the algorithm aims to preserve two local shape properties: the laplacian coordinates of the boundary curve and the local area of the shape interior, which are together represented in a non-quadratic energy function.
Poisson equation presented by : gagan bansal 3 ∆ f = div(w) , f is the unknown & w is the guidance field triangle mesh -not a regular grid approximate by discrete field and redefine divergence for discrete field. In the poisson-based mesh editing framework, the manipulation on the gradient ﬁelds of a mesh can be transformed back to the scalar ﬁelds of the mesh, ie the. Our mesh reconstruction part use gradient-based method  and  used , too so, we currently compare our method  for this study so, we currently compare our method  for this study other mesh reconstruction can be used instead such as volume-preserved method etc to preserve volume. This paper presents a novel inhomogeneous volumetric mesh deformation approach by gradient field manipulation, and uses it for maxillofacial surgery simulation.
Abstract it is a challenging problem of surface-based deformation to avoid apparent volumetric distortions around largely deformed areas in this paper, we propose a new rigidity constraint for gradient domain mesh deformation to address this problem.
