By finding attachment points between the mesh and skeleton, we enable con gurable skeleton and surface-based deformations, and avoid common skinning artifacts. Use of sketch-based interfaces and graphics hardware make both skeletal and mesh deformation simple to control and fast enough for interactive use.Computing methodologies AnimationShape modelingMesh geometry modelsshape controldeformationskinninganimation10.1145/3099564.3108161Nick Toothman and Michael Neff-Computing methodologies Animation; Shape modeling; Mesh geometry models; shape control, deformation, skinning, animation
