chroma/fileio, branch master

File reorganization to move toward standard python package layout

2011-09-16T18:27:46+00:00

add chroma-sim script. get rid of GPU class; contexts should now be created with create_cuda_context().

2011-09-12T20:41:17+00:00

update event structure. break gpu.GPU class into separate smaller independent classes.

2011-09-02T16:12:38+00:00

Add a RootReader class that also functions as an iterator, also create

2011-08-23T23:28:36+00:00

a simple unit test for event reading and writing.  There were several
minor I/O bugs that are now fixed!  Always test your code, kids!

Missing import from fileio.root

import chroma modules from subpackages with import chroma.module_name

Refactor sim.py into a reusable Simulation class that is called by the

2011-08-16T21:10:58+00:00

main function().  Also cleanup more event data structure names and add
an nphoton value that is preserved even if you prune off all the
actual photon vertices.

Epic restructuring of code to switch to a generator-based style of

2011-08-16T17:52:00+00:00

event creation.

Now we have vertex generators (that produce initial particles), photon
generators (that create photons to propagate), and a standard data
structure using Python class containers and numpy arrays to hand
around the code.

Also cleaned up some naming of things before they become conventions.

Add a helper function to the ROOT Channel class that will populate 3

2011-08-15T01:00:36+00:00

arrays with hit information: hit or not, time and charge.  Handy for
fetching all the hits in an event into numpy arrays.

G4Generator and sim.py can now generate boosted pi0 decays.

2011-08-12T17:58:52+00:00

The ROOT data structure has been extended to allow storage
of the individual gamma rays as subtracks.
