Subdivision Curve Primitives: a New Solution for Interactive Implicit Modeling
To remain an attractive model, skeleton-based implicit surfaces
have to allow the design and display of shapes at interactive rates.
This paper focuses on surfaces whose skeletons are graphs of interconnected
curves. We present subdivision-curve primitives that rely on
convolution for generating bulge-free and crease-free implicit surfaces.
These surfaces are efficiently yet correctly displayed using local meshes
around each curve that locally overlap in blending regions.
Subdivision-curve primitives offer a practical solution to the
unwanted-blending problem that ensures $C^1$ continuity everywhere.
Moreover, they can be used to generate representations
at different levels of detail, enabling the interactive display of
at least a coarse version of the objects, whatever the performance of the
workstation.
