In this article, we present an approach for employing a particular procedural modeling technique, L-systems, to produce a tree resembling one occurring in a set of input photographs. Our approach involves reconstructing the 3D volume occupied by the tree, constructing a plausible skeleton of the tree - its trunk and major branches - for this volume, and finally growing the remainder of the tree with an L-system. This approach retains the plausibility of output from a procedural model while providing a high degree of control over the final shape, resulting in efficient realistic reconstruction.
