Spherical Piecewise Constant Basis Functions for All-Frequency Precomputed Radiance Transfer
This paper presents a novel basis function, called spherical piecewise constant basis function (SPCBF), for precomputed radiance transfer. SPCBFs have several desirable properties:...

A logical analysis of aliasing in imperative higher-order functions
We present a compositional program logic for call-by-value imperative higher-order functions with general forms of aliasing, which can arise from the use of reference names as fun...
