Spotted: Image-based reconstruction and synthesis of dense foliage

It's hard to model plants with polygons. This looks like a promising approach: image based statistics.

Image-based reconstruction and synthesis of dense foliage

Derek Bradley, Derek Nowrouzezahrai, Paul Beardsley

Flora is an element in many computer-generated scenes. But trees, bushes and plants have complex geometry and appearance, and are difficult to model manually. One way to address this is to capture models directly from the real world. Existing techniques have focused on extracting macro structure such as the branching structure of trees, or the structure of broad-leaved plants with a relatively small number of surfaces. This paper presents a finer scale technique to demonstrate for the first time the processing of densely leaved foliage - computation of 3D structure, plus extraction of statistics for leaf shape and the configuration of neighboring leaves.
