We present a novel sparse sampling and reconstruction method for many-light rendering of participating media. We formulate the gathering of many lights as a matrix problem, and propose an adaptive matrix column sampling and completion algorithm to efficiently reconstruct the matrix by only sampling a small number of elements. Our approach greatly improves the performance, and obtains up to one order of magnitude speedup comparing to the state-of-the-art work.
