Title: Adaptive enumeration of implicit surfaces with affine arithmetic
Author: deFigueiredo, LH
Stolfi, J
Abstract: We discuss adaptive enumeration and rendering methods for implicit surfaces, using octrees computed with affine arithmetic, a new tool for range analysis. Affine arithmetic is similar to standard interval arithmetic, brit takes into account correlations between operands and sub-formulas, generally providing much tighter bounds for the computed quantities. The resulting octrees are accordingly much smaller, and the rendering faster.
