Bone handle generation

In a digital medium environment, a system for enabling efficient deformation of vector graphics objects in a way that preserves local coherence of portions of the vector graphics objects affected by the deformation, the system comprising:

• a mesh module, implemented at least partially by a processor of a computing device executing computer-readable instructions stored in memory, to generate a two-dimensional (2D) mesh corresponding to a vector graphics object based on an outline of the vector graphics object, the mesh module further configured to sample portions of the vector graphics object to identify whether sampled portions correspond to the outline or an interior of the vector graphics object and determine the outline of the vector graphics object based on the sampled portions;
• a mesh contraction module, implemented at least partially by the processor of the computing device executing the computer-readable instructions, to contract the 2D mesh to form a contracted mesh;
• an edge collapsing module, implemented at least partially by the processor of the computing device executing the computer-readable instructions, to generate a set of connected line segments forming a skeleton of the vector graphics object by collapsing edges of the contracted mesh;
• and
• a segment reduction module, implemented at least partially by the processor of the computing device executing the computer-readable instructions, to obtain bone handles for the vector graphics object by reducing a number of the connected line segments, the bone handles being controllable with user input to deform corresponding portions of the vector graphics object.

One or more non-transitory computer-readable storage media having instructions stored thereon that are executable by one or more processors to perform operations comprising:

• determining, by the at least one computing device, an outline of a vector graphics object by sampling portions of the vector graphics object to identify whether sampled portions correspond to the outline or to an interior of the vector graphics object;
• generating, by the at least one computing device, a two-dimensional (2D) mesh corresponding to the vector graphics object based on the outline;
• contracting, by the at least one computing device, the 2D mesh to form a contracted mesh;
• generating, by the at least one computing device, a set of connected line segments forming a skeleton of the vector graphics object by collapsing edges of the contracted mesh;
• and
• obtaining, by the at least one computing device, bone handles for the vector graphics object by reducing the set of connected line segments, the bone handles being controllable with user input to deform corresponding portions of the vector graphics object.
