Frisken, 2000. Adaptively Sampled Distance Fields: A General Representation of Shape for Computer Graphics
comments: An octree representation of volumetric shapes. But unlike octree, the cells split only when the variation of the points in this cell is larger than a bilinear or trilinear interpolation of it's boundary points.
comments: Can we modify this representation for manifold?
Another way to think about it is that whether this representation can be extended beyond scalar field (distance field in the paper) to high dimensional field?
