Displaced Subdivision Surfaces
To Appear in ACM SIGGRAPH 2000
Project Description
In this paper we introduce a new surface representation, the displaced
subdivision surface. It represents a detailed surface model as a
scalar-valued displacement over a smooth domain surface. Our representation
defines both the domain surface and the displacement function using a
unified subdivision framework, allowing for simple and efficient evaluation
of analytic surface properties. We present a simple, automatic scheme for
converting detailed geometric models into such a representation. The
challenge in this conversion process is to find a simple subdivision surface
that still faithfully expresses the detailed model as its offset. We
demonstrate that displaced subdivision surfaces offer a number of benefits,
including geometry compression, editing, animation, scalability, and
adaptive rendering. In particular, the encoding of fine detail as a scalar
function makes the representation extremely compact.
