Progress

Use hg-month n to review commits for the numbered month, negative n eg -12 for December of last year.

May

• start bringing materials to GPU via textures
• introduce the geocache
• material code translation in Lookup
• adopt ImGui

June

• develop highly compressed photon records
• ViewNPY machinery for OpenGL uploading
• get animation working
• add GOpticalSurface, for transporting surface props thru Assimp/AssimpWrap into GGeo
• learning Thrust
• OptiX 3.8 , CUDA 7.0 update

July

• photon indexing with Thrust
• verifying ThrustIndex by comparison against the much slower SequenceNPY
• auto-finding repeated geometry assemblies by progeny transform/mesh-index digests in GTreeCheck
• interim Linux compatibility working with Tao
• 4-GPU machine testing with Tao
• OpenGL instancing
• trying to get JUNO geometry to work
• computeTest timings for Juno Scintillation as vary CUDA core counts

Aug

• OptiX instancing
• intro BBox standins
• Thrust interop

Sept

• use interop Thrust/CUDA/OptiX to make photons fully GPU resident, eliminating overheads
• add Torch for testing
• investigate bad material for upwards going photons, find cause is bad geometry
• integrate OpenMesh to enable mesh fixing

October

• vertex deduping as standard
• IAV and OAV mesh surgery
• sensor handling
• identity with instancing
• analytic geometry description of DYB PMT via detdesc parsing and geometrical partitioning
• flexible boundary creation

November

• overhaul material/surface/boundary handling to allow dynamic boundary creation post geocache
• implement dynamic test geometry creation controlled by commandline argument, using “–test” option
• npy analysis for Fresnel reflection testing
• adopt more rational PMT partitioning surfaces (not a direct translation)

December

• prism test with Plankian light source using GPU texture
• rainbow comparisons against expectation
• cfg4 : new package for comparison against standalone geant4
• cfg4 G4StepPoint recording : creating opticks format photon/step/history records with cfg4-
• Opticks/Geant4 rainbow scatter matching achieved
• enable loading of photons/records into ggv, in pricipal enables visualizing both Opticks and G4 cfg4- generated/propagated events on non-CUDA machines
• begin revival of compute mode

January

• rework Bookmarks, split off state handling into NState
• add InterpolatedView for viewpoint animation
• JUNO meeting presentation
• PSROC meeting presentation

February

• create analytic geometry description of Dayabay PMT
• PMTInBox debugging
• compositing OptiX raytrace with OpenGL rasterized

March

• resolved PMT skimmer BR BR vs BR BT issue : turned out to be Opticks TIR bug
• PmtInBox step-by-step record distribution chi2 comparison
• rejig material/surface/boundary buffer layout to match OptiX tex2d float4 textures, with wavelength samples and float4 at the tip of the array serialization
• Dayabay presentation
• screen capture movie making
• GTC presentation

April

• GTC
• factoring usage of OptiX to provide functionality on non-CUDA/OptiX capable nodes
• CMake superbuild with CTests
• external get/build/install scripts
• prep for spawning Opticks repository

May

• shifts
• getting more CTests to pass
