As-rigid-as-possible surface modeling
Modeling tasks, such as surface deformation and editing, can be analyzed by observing the local behavior of the surface. We argue that defining a modeling operation by asking for rigidity of the local transformations is useful in various settings. Such formulation leads to a non-linear, yet conceptually simple energy formulation, which is to be minimized by the deformed surface under particular...
متن کاملAs-rigid-as-possible spherical parametrization
In this paper, we present an efficient approach for parameterizing a genus-zero triangular mesh onto the sphere with an optimal radius in an as-rigid-as-possible (ARAP) manner, which is an extension of planar ARAP parametrization approach to spherical domain. We analyze the smooth and discrete ARAP energy and formulate our spherical parametrization energy from the discrete ARAP energy. The solu...
متن کاملAs-Rigid-AsPossible Distance Field Metamorphosis
Widely used for morphing between objects with arbitrary topology, distance field interpolation (DFI) handles topological transition naturally without the need for correspondence or remeshing, unlike surface-based interpolation approaches. However, lack of correspondence in DFI also leads to ineffective control over the morphing process. In particular, unless the user specifies a dense set of la...
متن کاملShape-aware as rigid as possible deformation
We propose a formulation capable of deforming meshes in a shape-sensible way. We explain how to adapt the original space-deforming algorithm [2] into a skeleton-driven deformation scheme, where more sensitivity to the mesh geometry is achieved. The more natural results make it possible to use the technique for character animation.
متن کاملSkeleton Based As-Rigid-As-Possible Volume Modeling
Shape deformation and editing are important for animation and game design. Based on as-rigid-aspossible (ARAP) surface modeling, an efficient approach is proposed to approximately preserve the volume of an object with large-scale deformations. The classical ARAP surface modeling uses twostage iterations to recover rotations and preserve edge lengths. However, there is no volume preserving const...
