Hi,
I need information if HullAccumulator works well with PointCloud and if is based on https://en.wikipedia.org/wiki/Alpha_shape
Question
What kind of the algorithm for Alpha Value is implemented in HullAccumulator?

HullAccumulator creates 2D hulls, Z values will be ignored during the hull creation. FME HullAccumulator uses the same algorithm as described on the referenced wikipedia page, although we've enhanced it to also accept lines and areas. HullAccumulator only returns the bounds of a Point Cloud. To generate a hull you need to use the PointCloudCoercer to create points or multi-points and then pass those into the HullAccumulator.
