Subdivision for Modeling
and Animation
Subdivision is an algorithmic technique for
generating smooth surfaces as a sequence of successively refined polyhedral meshes. Its algorithms are exceptionally simple. They work for arbitrary control meshes, and they produce globally smooth surfaces. Subdivisionbased representations of complex geometry can be manipulated and rendered very efficiently, which makes it a highly suitable tool for interactive animation and modeling systems. This course covered the basic ideas of subdivision, a variety of subdivision schemes, and their properties, their suitability for particular applications, and their relative merits.
Prerequisites
No prior knowledge
of subdivision. Prior exposure to parametric representations of curves and surfaces, basic linear algebra, and introductory calculus required.
Topics
The basic ideas of subdivision for curves and surfaces, subdivision methods for surfaces,
a variety of subdivisionbased algorithms for modeling and animation, levelofdetail rendering, and manipulation.
