Box AsymmetryΒΆ

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.
