| 2011-08-08 | speedup Geometry.build() | Anthony LaTorre | |
| 2011-08-08 | Oops. The generator is a process, not a thread. | Stan Seibert | |
| 2011-08-08 | Merge Tony's changes. | Stan Seibert | |
| 2011-08-08 | Modify data structure to hold photon start and stop vertices separately. | Stan Seibert | |
| Add --save-photon-start and --save-photon-stop options to sim.py to save these vertices. Otherwise, only hit information is recorded. | |||
| 2011-08-08 | toggle fullscreen mode with f11 key. use matplotlib colors maps defined in ↵ | Anthony LaTorre | |
| matplotlib.cm. | |||
| 2011-08-08 | Switch sim.py to spawn a separate process for GEANT4 and start it generating | Stan Seibert | |
| photons while the detector geometry is being built. | |||
| 2011-08-08 | merge heads | Anthony LaTorre | |
| 2011-08-08 | add a simple event viewer. view events by running ./camera.py ↵ | Anthony LaTorre | |
| <detector_name> -i <name_of_io_file>. | |||
| 2011-08-08 | Ignore root files and .lprof files produces by kernprof. | Stan Seibert | |
| 2011-08-08 | Bug fixes when retrieving and rerunning photon lists through propagate. | Stan Seibert | |
| 2011-08-05 | Cut off the index of refraction for water below 260 nm, which can't | Stan Seibert | |
| be observed anyway. Speed increase of 20% in full size LBNE. | |||
| 2011-08-05 | Run a short dummy GEANT4 event to force it to load the tables before | Stan Seibert | |
| the timer starts on the real events. | |||
| 2011-08-05 | merge heads | Anthony LaTorre | |
| 2011-08-05 | update bounding box construction for nodes to determine each bound in a ↵ | Anthony LaTorre | |
| single call by calling np.min() and np.max() along an axis | |||
| 2011-08-05 | Fix typo in setting direction of particle from sim.py command line. | Stan Seibert | |
| 2011-08-05 | Remove the unused load() function from Geometry class. | Stan Seibert | |
| 2011-08-05 | Tony discovered that Inf is not a good value for a scattering length. :) | Stan Seibert | |
| 2011-08-05 | merge with tony | Stan Seibert | |
| 2011-08-05 | Warn user if for some reason the default BVH quantization is used because | Stan Seibert | |
| they didn't build the geometry before loading it on the GPU. | |||
| 2011-08-05 | --spnav option to camera.py enables camera control with a | Stan Seibert | |
| locally-attached Space Navigator 3D mouse. Assumes you have the open source spacenavd and libspnav installed. (Both included in Ubuntu now.) | |||
| 2011-08-05 | merge heads | Anthony LaTorre | |
| 2011-08-05 | speedup bounding volume construction of leaf nodes by taking the min and max ↵ | Anthony LaTorre | |
| of ungrouped instead of grouped vertices from a mesh | |||
| 2011-08-05 | add a pi0 decay generator | Anthony LaTorre | |
| 2011-08-04 | ctypes module for using libspnav from python | Stan Seibert | |
| 2011-08-04 | First attempt at a simulation program using Chroma. | Stan Seibert | |
| Loads a geometry specified on the command line, uses GEANT4 to create initial photon vertices, propagates with Chroma, then writes the DAQ-level hit information out to a ROOT file. | |||
| 2011-08-04 | A rootlogon.C file to load the Event dictionary when running root | Stan Seibert | |
| inside the Chroma directory. Put this in your home directory or other work directory to access Chroma ROOT files. | |||
| 2011-08-04 | Import the fill_event() method from ROOT into the root.py namespace. | Stan Seibert | |
| 2011-08-04 | Use the clear() method on Event to reset for filling. | Stan Seibert | |
| 2011-08-04 | Implement propagate and daq functions in gpu module. | Stan Seibert | |
| 2011-08-04 | Don't draw a random time delta in the daq kernel unless it is necessary. | Stan Seibert | |
| 2011-08-04 | Add method to detectors module to locate a detector build function | Stan Seibert | |
| using the same string decorators as in camera and view. | |||
| 2011-08-03 | Merge Tony | Stan Seibert | |
| 2011-08-03 | ROOT data structure for holding particle, photon, and hit information. | Stan Seibert | |
| 2011-08-03 | Ignore shared library files produced by ROOT and Boost::Python. | Stan Seibert | |
| 2011-08-03 | merge heads | Anthony LaTorre | |
| 2011-08-03 | add a GPU class to handle both the gpu context and module; since the ↵ | Anthony LaTorre | |
| geometry requires global device pointers, there should be a one to one correspondence between modules and contexts. the current plan is to perform all gpu operations within this class. also add a simple color map to display hit pmt charge and timing information. | |||
| 2011-08-03 | GEANT4-based photon vertex generator. | Stan Seibert | |
| Propagates a particle through a huge volume of some material and harvest the photon vertices that are created for propagation with Chroma. Relies on a patched version of g4py, plus a local boost.python module that is built at import time if needed. (Does not detect changes to rebuild, however.) Chroma materials can now have a density set, as well as an elemental composition (by weight) that is used by this generator. | |||

| 2011-07-30 | reduce number of lookup calls. | Anthony LaTorre | |
| 2011-07-30 | you can rotate just the camera by holding the control key and take movies by ↵ | Anthony LaTorre | |
| pressing the m key. | |||
| 2011-07-30 | when throwing photons from the light source out onto the scene, photons are ↵ | Anthony LaTorre | |
| now thrown randomly across each triangle instead of only at the center of each triangle. all of the rendering kernels have been rewritten so that they operate additively; for example, you may now throw photons from the light source onto the scene, render from the camera to the scene, then throw more photons and render again. | |||
| 2011-07-29 | Add SNO acrylic and LAB+PPO scintillator to detector model. | Stan Seibert | |
| 2011-07-28 | Alternate "real_sno" detector configuration using the CAD model of the | Stan Seibert | |
| acrylic vessel. There are serious issues with this model which probably make it unsuitable for photon propagation at the moment. (Example: Why do you need to traverse 8 surfaces to cross the acrylic vessel? There should only be 4.) | |||
| 2011-07-28 | Oops, forgot to include the reduced 8" PMT profile. | Stan Seibert | |
| 2011-07-28 | Increase alpha depth for complex models. Remove intermediate rounding | Stan Seibert | |
| to integers in alpha blending until the last step. | |||
| 2011-07-28 | Support for reading bz2 compressed STL files. | Stan Seibert | |
| 2011-07-27 | Merge changes | Stan Seibert | |
| 2011-07-27 | Use the more realistic SNO database and add PMT concentrators. | Stan Seibert | |
| 2011-07-27 | camera automatically increases render quality when it is not being moved | Anthony LaTorre | |
| 2011-07-26 | Preliminary SNO detector. | Stan Seibert | |
| PMTs in the right place and acrylic vessel. No new material properties yet. | |||
