We describe a new approach for creating concise high-level gener-
ative models from range images or other approximate representa-
tions of real objects. Using data from a variety of acquisition tech-
niques and a user-defined class of models, our method produces a
compact object representation that is intuitive and easy to edit. The
algorithm has two inter-related phases: recognition, which chooses
an appropriate model within a user-specified hierarchy, and param-
eter estimation, which adjusts the model to best fit the data. Since
the approach is model-based, it is relatively insensitive to noise and
missing data. We describe practical heuristics for automatically
making tradeoffs between simplicity and accuracy to select the best
model in a given hierarchy. We also describe a general and efficient
