Box Asymmetry =================== PmtInBox shows almost no scatters in two directions, whereas expecting symmetry:: ggv-pmt-test * Switching from analytic box to analytic sphere shows no asymmetry * Switching off analytic also shows no asymmetry, but currently the analytic applies to the PMT too (which is too unrealistic to pursue) Retreat to single box, can see the scatter asymmetry by flipping the analytic switch:: ggv-box-test(){ type $FUNCNAME local torch_config=( type=disclin photons=500000 wavelength=380 frame=1 source=0,0,300 target=0,0,0 radius=100 zenithazimuth=0,1,0,1 material=Vacuum ) local test_config=( mode=BoxInBox shape=box analytic=1 boundary=Rock//perfectAbsorbSurface/MineralOil parameters=0,0,0,300 ) ggv \ --test --testconfig "$(join _ ${test_config[@]})" \ --torch --torchconfig "$(join _ ${torch_config[@]})" \ --animtimemax 10 \ --cat BoxInBox \ --eye 0.5,0.5,0.0 \ $* } Issue apparent for "TO SC SA" but thats probably coincidental and its just a geometry issue ? Fixed issue with *intersect_box* was wrongly to conflating the slightly enlarged aabb with the contained box.
