puts "Visualization - improve selection mechanism"
# tests performance of selection algorithm. Creates a grid of spheres with
# size DISCRETISATION * DISCRETISATION. To get representative performance
# test results, increase the size of grid in DISCRETISATION and check time
# measurments in comparsion to previous OCCT versions. You may also check
# the time of selection when all BVH trees are built via uncommenting
# the code in "Start building all trees" section.
