Could you please tell about vector cross & dot products too, then? :o)
I've read the Pov docs, and 2 webpages explaining their use in Pov, and I've
searched on math pages, but still don't understand.. I don't have a higher
mathematical education and until recently I didn't know how important the
origin <0,0,0> is regarding to vector functions.. Now I do know that
everything involves origin, but I still can't SEE in my mind the picture of
cross & dots.. The examples in Pov with 3 cylinders pointing in each their
way, doesn't help.. I tried animating them too but..
You could argue that I should take a further education, but I don't have
time for this (I have work, and would have to change my life drastically)
and I'd prefer to learn in my sparetime.. Any clear and throughfull
explanation in simple english will be appriciated! :o) When you have
time..
Regards,
Hugo
