Detailed Description

AbstractVolume is an abstract class for Volumetric data (can be parametric or discrete, with dense or sparse storage).

Note: Right now the encoded function \(f\) is dimension 1, ie. \(f:\Re^3->\Re\). If needed, the class can be templated so the built-in typedef ValueType is replaced by a parameter.; This class could also be modified to encode n-dimensionnal textures. See this for an implementation of n-dimensionnal grids with neighbhorood queries (compile-time loop unrolling): http://github.com/STORM-IRIT/OpenGR/blob/master/src/gr/accelerators/normalset.h
