abstract = "We present an efficient stratified sampling technique
for an ellipse. Our technique provides extensions of
previous work for sampling a disk with low distortion;
it works for both polar and concentric maps between a
square and an ellipse. The mapping preserves adjacency
and fractional area, and does not require any numerical
computation. As in the previous work, the concentric
map demonstrates better performance. Our technique has
proven useful in realistic image synthesis using Monte
Carlo direct lighting and Monte Carlo path tracing. In
conclusion, the proposed technique is stratified,
efficient, and feasible for the computer graphics
community. Source code is available online.",
