Description:
the om equivalant of the modalisp
(transform 'reflection sth-to-be-reflected normal-vector invariant-point),
!!!! the function is still a bit problematic, when the normal vector is not 1.. but sth strange like (6 2 1), it will scale the object not proportionally in each directions.. so please help to correct the formula in the function (point-reflection) if you know better about the modalys algorithm.!!!!
!!! 2D reflection works not normally.. Some point jumps quite strange.. should have an individual formula which is quite simple !!!
the first argument could be:
1. point of (list x y z)
2. list of points of (list x y z)
3. bpc (or in some case bpf)
4. bpc-lib (or in some case bpc-lib)
5. 3dc
6. 3dc-lib
