- Digital ink allows for fluid and direct input without formalization.
- Digital ink can be modified after drawing, unlike traditional pen and paper.
- Deforming ink strokes involves changing their shape, which can be manual or dynamic.
- Vector graphics tools allow for easy deformation but lack the fluidity of hand-drawn ink.
- The challenge is to maintain the fluidity of hand-drawn ink while enabling dynamic manipulation.
- Ink deformation can be broken down into three steps: control structure, mapping, and deformation.
- Simplified geometry approaches convert ink strokes into vector graphics for deformation.
- Nudging, pushing, and pulling techniques allow for direct deformation with minimal control structure.
- Scale, stretch, and warp techniques provide simple ways to deform ink.
- Skeletal deformation uses bones to influence the position of points in the geometry.
- Free-form deformation generalizes cage shapes to arbitrary polygons for deformation.
- Physically accurate deformation techniques simulate material properties but are computationally expensive.
