Description
A toolkit is presented that takes a set of reconstructed particle tracks as its
input and produces reconstructed interaction vertices as its output. It deals
both with finding (pattern recognition) and with fitting (statistical
estimation) of the interaction vertices. Its main design goals are ease of use,
high integratability in existing software projects, extensibility, and
generality. To this end the API is defined in an as simple as possible way.
The various algorithms, and optionally, their parameter settings, are
referenced by a simple string. This guarantees that the user code decouples
completely from the toolkit internals. Also, maintaining backwards
compatibility should become a trivial task. The Rave Toolkit is complemented
by a simple standalone framework, called ”Vertigo”. Implementation,
verification, and performance analysis of reconstruction algorithms should
thus be possible in a very fast and straightforward manner. Rave has its
roots in the CMS vertex reconstruction community. The current algorithmic
parts of the toolkit are source code compatible with the original CMS
software, but contributions from ”outside” are highly welcome. The toolkit is
written in C++, but interfaces for other languages (Java, Python) have been
implemented via ”SWIG”. Applications outside the high energy physics
community (e.g. in astrophysics, or nuclear physics) are highly desirable. An
online demonstration of the toolkit with 3d graphics based on coin3d can be
arranged. Thanks to the CMS Track and Vertex Reconstruction group, whose
code is reused heavily in this project.
