Local deformers

• Variety of interactive local and parametric deformers in 3D modeling softwares

• Example: Applying a translation \(t\) only locally around \(c\)
• • \(q = p + w(p_i) \,t\;\) , \(\;\;\;w_i = \exp(-\|p_i-c\|^2/\sigma^2)\)

• • \(t\) can be controled interactively
  • • and other parameters (rotation axis, angle, etc) as well.
